This autumn/winter, I planned to refurbish my 2010 Cervelo P3. Over the last year or two, I’d gone from 9 speed to 11 speed Dura-Ace, so that I could swap wheels with my main time trial bike, a Cervelo P5, which is presently equipped with SRAM eTap kit and concealed Magura RT8 hydraulic brakes.

The main intention of the remodelling was to reduce the amount of cabling exposed to airflow on the P3, and generally make the bike a bit sleeker. The P3 is quite a bit bit lighter than my P5 bike, so I have the intention of using it on rather more undulating courses where its monstrous top gear is rather useful on long descents.

I realise I haven’t blogged too often about time trialling (and cycling in general) this year. That reflects considerable personal and work-related things getting in the way of (a) training, (b) racing, (c) cycle touring and (d) blogging.

At this point, I could note that our summer cycle tour had been planned to include many Outer Hebrides. It went seriously awry when a road accident delayed us while driving to Oban for the first ferry, which we subsequently missed by seconds. As it turned out, this was a good thing as Storm Hector blew in later that day, closing down the ferries we’d planned to use in the tour. So that was that.

So now I've started, I'll continue!

This event was held on a spectacularly sunny and warm afternoon. I rode over to the HQ in Lidlington. This was a pleasant ride marred only by a puncture  just after riding through Ridgmont. I only got a little mucky while changing the inner tube, but of course the little mini-pump only gets the tyre pumped up to a 'get you home' pressure, and it wasn't until I got to Lidlington that I could pump it up properly with the help of a borrowed track pump (thanks, Trevor).

The 2018 season has been pretty awful so far. I had not completed a single one of the NBRC events (which began in early March). Roughly speaking, these fell out as follows:

Sat 3rd March, Astwood - Event abandoned due to snow

I live and time trial in the London North District, where the flagship course over many years has been the F1, which uses the A1 dual carriageway (formerly the Great North Road). The Great North Road has been significant in the history of English time trialling over the years. Nowadays, events on the A1 in this area are restricted to the stretch of road between the Black Cat roundabout and the Baldock interchange, where the A1 becomes the A1(M) and beyond which bicycles aren't permitted. When I first moved down here, things were different, with time trials reaching thr Alconbury interchange - over the years, I've ridden a variety of course permutations - the majority of which are based on a start point near Tempsford (and usually using the Stuart Memorial Hall in Tempsford.I'd been aware of the F. T. Bidlake memorial near Sandy for some time, but until today hadn't actually visited. There's a brief biography of Frederick Thomas Bidlake (1867-1933) at wikipedia - put briefly, his role in English time trialling was significant.In the 1890s, cycle racing on roads was threatened following an incident between a couple of racing cyclists (Bidlake and a friend, pluse their pacers) and a lady with a horse which, startled by the cyclists, reared causing the cyclists to wind up in the ditch. Despite the fact that most damage was caused to the cyclists, complaints to the polices about cyclists' behaviour led to concerns that cycle riding on roads might be banned - at the time there was some pressure to amend to Highways Act. To forestall this, the National Cyclists Union banned racing on the road and insisted competitive cycling should only take place on tracks (known as 'paths' in those days).Not everyone agreed with the NCU's decision, and a rival organisation was set up - the Road Racing Council - and Bidlake organised a road race on 5th October 1895 which essentially used the time trial formula used to this day. Though it's not true to say Bidlake invented time trialling, he was one of those who codified the sport.Bidlake worked in a number of sports, including the Scheider Trophy for seaplanes in which he was timekeeper. Ultimately, Bidlake died three weeks after a fall on Barnet Hill due to collision with a car. The memorial was erected in 1934 after a public subscription. It's quite a modest affair, with a box hedge enclosing a triangular plot near the A1 at Sandy. Here's a Google Maps link that shows where it is.[caption id="attachment_4097" align="alignnone" width="1000"] The Bidlake memorial garden - in a rather inaccessible location[/caption]There's a stone pedestal that looks to have had something cut off - from the Wikipedia page, I think it formerly supported a sundial - with a legend "He measured time".[caption id="attachment_4096" align="aligncenter" width="563"] The pedestal that formerly held a sundial[/caption]Above a bench, there's a plaque inscribed

THIS GARDEN IS DEDICATED TOFREDERICK THOMAS BIDLAKEA GREAT CYCLISTA MAN OF SINGULAR CHARM & CHARACTERAN UNTIRING WORKER FOR CYCLISTS1867-1933

The bench itself is a commemoration of Bidlake's colleague George Herbert Stancer, and indeed Stancer's ashes were scattered in the the memorial.

Team Grumpy assemble for two regular events each season - aside from the Duo Normand in September, the team generally opens the season with a ride at the Port Talbot Wheelers 2-up '25' in early March. 2018 was no exception. This year (as last year), the event was shifted to the fast R25/3H instead of the more rolling course usually used, owing to roadworks.

The team had the usual preparation of curries, beers and crisps in the preceding days, and after a little worry about the weather (there was heavy rain the day before and on the day after the event), was more than a little relieved to have dry conditions. There was some wind, of which more later.

It's been a while since I updated this blog. After the 2017 season finished, I began my usual winter training programme - after a short break I started a build up towards the New Year's Day '10'. Unfortunately a series of events significantly more important than training impacted on me, and my training suffered, and I did not ride the New Year's Day '10' for the first time in many years.I'd been looking forward to the opening event of the North Bucks Road Club time trial series. This was a Saturday morning event to which we'd hoped to attract newcomers. Unfortunately we have had a modest snowfall, and the event got cancelled. So, not much of a blog entry. Perhaps there will be a bit more action next weekend!In the meantime I discovered that the left hand Speedplay pedal on my main time trial bike (which hasn't been ridden since the Duo Normand) has pretty much seized up. I've tried injecting copious grease but that doesn't seem to have sorted the situation, which is sufficiently serious that I have taken the extraordinary steps of resorting to eBay to buy a set of replacement bearings. Hopefully they will arrive in time to overhaul the pedals before next weekend's time trial (which is the first open event of 2018 for me -  a 25 mile 2-up).

After a couple of weeks without racing (and indeed a week off the bike), I turned out for the club '10' on a sunny evening at the end of May. I've been getting a little concerned about the downturn in my form lately, which is partly why I took a bit of a break from training, so I was keen to see how this evening's '10' would go.I was quite a late starter in the field, and it was clearly quite a nice evening for a '10'. The starting stretch was OK, I avoided overcooking it at the start. Sadly, once I turned left up the DC drag, things went a bit pear-shaped. I clipped the edge of a large pothole (the whole course suffers from too many road defects), which bounced out my bottle, and caused me to run into the grassy verge. I was rather exasperated, at this and decided to get off to retrieve the bottle and check the bike was OK. I noticed that the impact had loosened the ratchet on my left shoe! So, by the time I'd got sorted, given the bike a quick once-over, and tightened up my shoe, I'd lost about a minute and 20 seconds. Despite that, and the fact I was having to get going on an uphill stretch, I decided to complete the course.After my altercation with the pothole, I was acutely aware of the remaining numerous potholes, which I managed to avoid. Also, there were no traffic related holdups! I finished with 24:40, not too shabby given the disastrous ride!

Just a brief report here, drafted a month late. This event was run on a lovely spring afternoon, very warm and dry. A bit breezy, but no too bad. I'd travelled over with James, and we were about an warming up with plenty of time. Sadly, while James pulled off a 49:51 (I think he was 23rd, on a day when the third fastest '25' was recorded), all I could manage was 56:35, probably about a minute slower than I'd have expected. I have no idea why my form dipped so much (but I have some worries on that score). On the day, I just couldn't get comfy on the bike, and couldn't keep a steady effort. And getting slowed up at the turn wasn't a great morale-booster either. Oh well, onwards and upwards. I hope! 

Quite breezy for this morning's time trial on the F15/10. Having "missed out" on the previous weekend's Hardriders event (I marshalled in Woburn Sands), it was good to get the cobwebs blown off. From home it's only a few miles over to the Brogborough course, and about the right distance to make sure the legs are spinning well!Getting down the Brogborough hill was pretty good - not too twitchy as I passed the underpass. I did see one club mate walking back with a puncture near the Marston Moretaine RAB - no such misfortune for me fortunately. The direction of the prevailing breeze was mostly affecting the return leg and as is so common, the last few hundred metres to the line seemed to take an eternity!I finished in 23:11, not too bad, but I had hoped for a quicker ride, I guess.

I had reasonable hopes for this event - it's a nice DC course with a smooth turn at the Cambridge end. I travelled out with Katja, who's start was (as I recall) about 4 minutes after me. It was fairly breezy  on the day. In fact, when I went out to warm up it was obviously going to be quite hard on the return leg.Based in Cambourne, the F2D/10 starts on a minor road, but soon makes a sharp left turn at a roundabout to go down the slip road on the A428 in the Cambridge direction. There was a rather neat tailwind for much of the outbound leg, and it was good riding, with not too much traffic. Until, that is, when an enormous honking startled me just as I entered the slip road for the turn. It quickly became apparent that this was emanating from a correspondingly enormous truck, which came up the sliproad past me, though giving me plenty of space. Worryingly, it was followed by a line of at least 6 cars, and I feared I'd get held up at the turn. The turn is quite fast, with gentle and well-cambered curving turn to a roundabout - when I approached the roundabout, the entire train of traffic was in the left hand Cambridge-bound lane, and I had a clear run through to make my turn.As feared, the stiff headwind on return leg made things a bit difficult! On some of the rises, I was embarrassingly slow. I just grit my teeth and pressed on as best I could. The exit from the DC to finish is often a bit troublesome with traffic at the roundabout - today I had not real issues, and stamped on the pedals to record 22:32, about what I'd expect for the course and conditions. 

This was the first event of the season with a major effort required for placing warning signs.Nathan and I went round placing signs - the whole exercise took rather too long and left me with a bit of a dash to get back for the race itself (thanks to Carol for the lift). Without a proper warmup, I felt pretty sluggish to start with, but pulled through to finish with a 24:01, which I was reasonably pleased with given the time of year and the lack of a warmup. Actually, I ended up in such a rush that I failed to engage the Garmin effectively - missing the start of the race!

The Port Talbot Wheelers 2-up event is usually my first open event of the season, and the first of Team Grumpy's two regular 2-up events in the season (the other being the Duo Normand, of course). In recent years, the event has been run on a course that is half dual carriageway and half lumpy back roads - actually an excellent test of a 2-up team. This year, the organisers used one of the R25/3 variants, including the descent of Neath bank, a hill riders don't have to race back up. Consequently it's a course that delivers consistently fast performances. My view is that it's not so good as a test of 2-up skills, but it does make a change.My preparations for the event were somewhat hampered by a 4 day trip to the USA, followed by a mucoid cold I presumably picked up in my travels, so I didn't really have too much optimism for the event. But at least the cold was pretty mild other than having blocked airways - and who breathes through their nose when racing anyway!The version of the course started in an industrial estate near Rhigos. While we were 'warming up', the forecast rain started. It wasn't particularly cold though. We set off briskly and joined the main road into a relatively gentle headwind, but enough to make us look forward to the descent! Gerry felt the beginnings of his exercise-induced breathing issue at this point, but I think this eased as we began the descent. In the past, Gerry has had alarming moments on this fast descent, albeit in windier conditions, so he's often a bit nervous - not today, though.Once at the bottom, it was a matter of keeping up reasonably frequent changeovers. I think we rode well technically, though an inspection of my Garmin trace indicates our speed tended to fluctuate rather a bit. We did get slowed twice at roundabouts, once in the outbound leg by a car, and then on the return leg by what appeared to be a funfair (!) travelling up the course.We crossed the line in 56:18, I think giving us 27th place. Full results at the CTT website 

After the uncertainty around this event, it went off almost without a hitch and with a sizeable turnout of riders.I rode up to the BikeBus in time to see Tony setting out the signs around the start, and then went out with Bryan to place signs out on the course (at this point, there seemed to be about 5 or 6 riders). Out near Chicheley Hall, we found a car that had rolled off the road. Luckily, there didn't seem to be casualties, but police had been called and there was a copious amount of mud on the road. And the car seemed to be pretty badly bashed up.We returned to the BikeBus to alert riders to this hazard, and discovered well over 30 riders had turned out! At this point Ian Stokes offered to drive down to the scene of the crash to check it was still passable - in fact he remained there while the riders passed through and made sure the road was kept passable for us (when I came through as number 37, most of the mud had been removed).I finished with a modest 25:17. Full results are at the NBRC website.Apart from that, the event went very smoothly. I didn't feel particularly ready to race, what with being off the bike for 5 days for a trip to the USA. On the other hand, I felt pretty comfortable in an aero tuck, and it was good to confirm that the bike was fully functional again after the Blipbox failure of November-December.  

Just a brief update on my last posting about the SRAM eTap Aero kit. I now have a fully functional eTap set up on my main time trial bike, almost two months to the day that I first reported the defective blipbox to the mail order retailer.Since mid-December, I've periodically communicated with the retailer by email (though it's not been obvious who to email) and via Twitter direct messaging. I've also contacted SRAM via Twitter and then email, to try and get a handle on where the problem has been. As far as I can tell, there have been supply chain problems somewhere along the line, though there seem to be some startling communication problems within the retailer.Anyway on Tuesday I received an email telling me the replacement blipbox had been packed and posted for next day delivery. About half an hour later, I received a second email (from an other person at the retailer) saying that the blipbox had been listed as present in a consignment, but that it was missing, so a further delay was to be expected. I replied, querying this information, and got another email saying they'd got it wrong, and the blipbox was indeed out for delivery.And it arrived, first thing the following morning! That evening, I fitted it, paired the gear mechs, and all is now fine with my time trial bike. The whole sorry tale has been a bit of a saga, and I am at least rather pleased it happen out of the main racing season.

I guess I'm really a sucker for  this sort of thing: a miniature toolset that offers a portable torque wrench of 2-8Nm all packed in a quality pouch with a wide range of bits (2, 2.5, 3, 4, 5, 6 mm Hex key; T10, T20 and T25 Torx; and a PH2 Philips) and corresponding driver ratchet. A rather blingy tool probably useful as a portable toolkit. After perusing various online emporia, I decided to place the order directly with Silca in Indianapolis.

This is an event that's always a good start to the year, despite the generally cold weather: it's good to blow the cobwebs off, and it's a change from turbo training! The weather forecast was pretty appalling: heavy rain starting well before the event, and continuing all day. Despite this, we had 17 riders show up, along with two timekeepers, a marshal (and sign placer) and a pusher off - thanks, Steph, Tony, Bryan and Dick!Fortunately, the forecast rain wasn't in evidence as we all signed on and rode the event. For me, the race was a bit of an eye-opener. Quick at times, I found it pretty tough going a lot of the time. I have no idea why this was - there wasn't really much wind out there. Every time the road went gently up, my speed dropped away. At least I was reasonably comfortable on the bike. I finished in 4th place with a disappointing 25:24. Still, I was first NBRC rider (I think the other guys were on rod bikes!).The rain held off until I was setting off to ride home - it got pretty heavy, and I got home completely drenched and cold.Due to the problems I've been having with the eTap Aero setup on the P5, I had decided to ride the P3 today. It's current configuration has Powertap P1 pedals, with vintage wheels: Hed Stinger 90 front and Corima disc rear. I've recently upgraded this bike to 11-speed, to ensure interchangeability with the P5. This itself was a bit complicated as 9-speed freehubs won't take a Shimano 11-speed cassette.Full results at the NBRC website. Here's the Garmin trace:

This is a longer-term update: I've ridden with the eTap Aero group on my Cervelo P5 for pretty much the whole of the 2016 season, from mid-March through to my traditional season closing event, the Duo Normand in late September. During this period, the set has performed flawlessly. Until the end of the season, that is - see the end of this report for more on that.I did find that the old style Campagnolo Record chainset, which was 9-speed and with a pair of third party TA rings, wasn't ideally suited to the 11-speed transmission. In fact, I found that the chain tended to drop between the rings. So in the end, I decided to buy buy a newer model. I like the Campag Ultra-Torque system, so I stuck with Record - though the new four bolt rings seem to a bit more inflexible regarding third party chain rings. Still, 53 x 11 ought to be big enough for anyone!One of the particularly annoying things about the (frankly rather expensive) eTap Aero set was the lack of sensibly designed switches for the ends of the handlebar extensions. Initially, I mounted the blips on the underside of the extensions, just down from the ends of the bars. This has the effect of requiring a distinct movement of hands to effect a gear change, which wasn't ideal. So I mounted the blips by virtue of classic bodging into the ends of the extensions. This worked well, and served me well until the end of the season, by which time SRAM had finally brought out *proper* extension-end switches, called **clics**. Mind you, these are unreasonably expensive for components that by right ought to have been part of the group to start with.Above: modified blip switches, mounted in the ends of extensions. This bodge involves bits of bar plug, tub tape and black insulating tape!Below: The real McCoy - expensive SRAM clic switchesDuring use, I had no issues with batteries running out. The Garmin 520 I use links well with the eTap system, with display options such as current gear selection (which is surprisingly useful) and battery status. the Instruction leaflet cautions agains transporting the bike with batteries attached in case they discharge - the gear mechs are motion sensitive. In use, i didn't find this an issue for drives of up to an hour to an event, and even the 12h journey to Normandy for the Duo Normand.I do have a problem with the eTap system to report. In November, shortly after the racing season finished, I noticed that one of the inputs to the blipbox was no longer functioning. By switching blips between the inputs, I concluded that the input rather than the blips was at fault. I arranged a return to the mail order supplier in mid-November. At the end of December, I am still awaiting a replacement blipbox. This rather unsatisfactory turn of events somewhat reduces my enthusiasm for the eTap system. It's not clear whether the issue lies with the mail order supplier or with SRAM (who may have supply problems). More later on this.

Most of my ‘serious’ and focussed training is done in the garage on a turbo trainer - the time available to me for training is quite limited, and consequently I train before going to work, so usually around 6am. I therefore use the turbo trainer all year round. For the last few years, I’ve been using the iOS app Motivo to manage my turbo training sessions. Unfortunately, I’d recently been having trouble pairing my ANT HR strap to it (and occasionally this problem affected any of my devices). Whether this reflected a problem with my iPad ANT adapter, I’m not sure. In any event, TrainerRoad appeared a bit more robust in this regard. It hadn’t escaped me that TrainerRoad also features turbo trainer control via ANT_ FE-C.[caption id="attachment_3723" align="alignnone" width="234"] The venerable Cateye CS-1000 turbo trainer[/caption]My primary indoor turbo trainer over the last 20 years has been a Cateye Cycle Simulator CS1000. This is a pretty solid device which was very stable in use, and lasted me well. It got rather rusty, the head unit failed, the fan cover broke, the head unit fell off, the variable magnetic load got stuck, and finally the bearings sounded a bit shot (given the amount of use, this thing lasted very well indeed). So I figured I’d buy a new turbo trainer. Looking around, I had to decide whether I’d stick with a ‘dumb’ turbo, or upgrade to one of the increasingly ‘smart’ turbos now available. Also, whether I go for one of the newer ‘wheel-out’ turbos or stick with one that left the rear wheel in place with the tyre against a roller.After a bit of thought, I decided to go seriously upmarket. After all, I do spend a lot of time on the turbo and as I mentioned, it’s where I do most of my training. I therefore looked at trainers such as the Tacx Neo and the Wahoo Kickr and decided to go for the Tacx Neo, which was subject to a bit of a reduction at Wiggle (plus I got a further reduction as a frequent customer). I reckoned that if The Tacx lasts as long as the Cateye, it won’t have been a major expense. The DC Rainmaker blog was invaluable for this decision - see his latest review of indoor trainers, his detailed review of the Tacx Neo, and his explanation of ANT FE-C.In due course, a massive and very heavy box arrived from Wiggle. I humphed the thing into the garage and began to unpack it. As well as the turbo trainer itself, there’s a front wheel riser block, a power supply, a skewer and a cassette lock ring and spacer set. The bike I’m currently training on is an old retired steel TT frame, running 9 speed Shimano transmission, so I whipped off the cassette and installed that on the Tacx freehub, which is made by Edco and can take cassettes with Shimano or Campagnolo splines. It’s a little fiddly as the splines aren’t as obvious as on a true Shimano or Campagnolo freehub body, but it’s not difficult. I have both Shimano and Campagnolo lockring tools in my toolkit, so no problems there.[caption id="attachment_3729" align="alignnone" width="430"] The Tacx Neo Smart trainer. There's also a power brick not shown.[/caption]Once the side arms/wings are unfolded and locked into place, the turbo has a rather SF-style appearance, a bit like a TIE fighter designed by Batman. Its weird appearance is enhanced during use by the unearthly glow it emits from its underside - blue at light intensity, purple at intermediate intensity and deep red when you’re absolutely hammering it. Structurally, it seems very robust, though the outer shell is some kind of plastic.[caption id="attachment_3732" align="alignnone" width="796"] Here's a picture showing all the bits inside a Tacx Neo. No flywheel![/caption]Fitting a bike to the turbo is very easy though I find bikes with rear facing dropouts such as my Cervelos are more of a hassle and you can get a bit oily. For the most part, this isn’t an issue for me, since I leave the training bike mounted to the turbo, and I’m not going to cart the Neo off to races for warmups on anything like a regular basis. 22kg of turbo in and out of the car is likely to give me back issues! The supplied skewer works well, and the bike when mounted seems very secure. Interestingly, and in contrast to the traditional turbo trainers I’ve used in the past, the bike mounted on the Tacx Neo can lean a bit from side to side, which is a little disconcerting at first but eventually feels a bit more like riding a bike for real. The original model, which I have, has rather tight clearances against the more exotic carbon frames (typical of TT bikes), and the Neo has been modified for 2017 to give a bit more clearance, though the internals are unchanged. My Cervelo P5 does fit. Just. I know this because somewhat unbelievably I carted this behemoth of a turbo trainer all the way to Normandy to warm up prior to the 2016 Duo Normand!There are Android and iOS apps available on the respective app stores which enable firmware updates and so forth. The Tacx Neo doesn’t require calibration. In use, the Neo is very quiet, with most of the noise coming from the drive train. I have almost exclusively used it in Erg mode, with resistance controlled by TrainerRoad. I found this a bit disconcerting at first. I’m used to easing off a bit as I tire during a training session, but with the Neo, the cadence just drops away while the head is maintained. So, the first lesson is not to overface yourself with an over-ambitious interval session.Pros - very quiet; very heavy and stable; good feel; doesn’t require calibration; works with or without external power; ANT Fe-C and Bluetooth Smart compatibleCons - first generation casing doesn’t accomodate all frames (my P5 fits (just!); very heavy - at around 22kg, you need to think carefully about taking it with you for warmup!Things I’ve not explored: I haven’t tried Zwift, mostly because it doesn’t appeal to me; I haven’t tried using my Garmin 520 to replay a course previously ridden, mostly because I haven’t got around to it.Notes -

1. The turbo requires a cassette which isn’t supplied, you can use either Campagnolo or Shimano (I’ve used 9-speed and 11- speed Shimano cassettes) - it’s an Edco freehub that takes both. Fitting the cassette is pretty straightforward, though check you have the correct splined tool.
2. The Tacx Neo doesn’t come with software , but does have a discount voucher for the Tacx software. I downloaded the Android and iOS apps for managing firmware updates and so forth, but I didn’t download the Tacx software for using the turbo, as I intended to use TrainerRoad.
3. If you plan to use the Neo with a PC or Mac, you will probably need an ANT USB stick. TrainerRoad have released an beta Android version of their app, both my Samsung devices have built in ANT . iOS devices do not, so an external dongle will be needed, and I don’t know if there is one available for lightning connectors.

I’ve been something of a retro-Luddite when it comes to gear-shifting technology. Party this is because I had several 9 speed race wheels, and I wanted to maintain interchangeability between bikes, and (I am embarrassed to admit) I found it difficult to figure out which parts I'd need to buy to set up a TT bike with Shimano Di2.Enter SRAM’s new electronic gear system, eTap. For road bikes, this is a pretty straightforward system. Each brake lever has one gear change switch, and it operates the derailleurs wirelessly. Satellite shifting switches (the ‘’blips”) allow shifting from the top of the bars or clip-on aero bars. The right hand control shifts the rear mech up, the left control down. Pressing both controls at the same time changes the front mech either down or up, depending on which position the mech is currently in.This spring, SRAM released the eTap Aero, intended for use on TT and triathlon bikes. I decided it was time to (a) get modern, and (b) get 11 speed. So I set my Wiggle profile to email me when the eTap aero was available. Ages later, I got an email saying it was in stock. I popped over to the Wiggle website to find four sets were available. I ordered one, along with an 11-speed Dura-Ace cassette and an 11-speed SRAM chain.The box.A few days later a vast box arrived at work. The post room called saying they thought a wheel had arrived for me! Inside was the cassette and chain, and an enormous and very heavy black and red box that just exudes quality.[caption id="attachment_3638" align="alignnone" width="474"] This image shows the six smaller boxes (sourced from the Slowtwitch forum, and edited)[/caption]Inside that were six smaller but equally robust boxes containing:

1. USB battery charger. This comes with all sorts of wall socket adapters, and is for charging the derailleur batteries.
2. The rear derailleur,  with the battery detached. The red part covers and protects the attachment point of the battery: there's a complementary part to protect the battery - the front derailleur comes with identical parts.
3. The blipbox. This is quite small, and has a Garmin style twist mount, there are several included. Neither mount with self adhesive pads matches the curvature of the top plate of my aerobar, so I used the normal Garmin mount held in place with stretchy bands (but see below).
4.  One USB stick for firmware updates. Just the USB stick. Nothing else other than a few scraps of paper.
5.  The front derailleur. This has the battery detached for transport, and a buch of weird little wedgy things, about which more later. Also, it has a horribly alarming sticker saying you MUST read installation instructions before using it. You need to retrieve said instructions from the SRAM website.
6. Two sets of 'blips' (i.e. four blips in total). These are the switches that connect to the 'blipbox', which actually controls the derailleurs wirelessly. So, not much in that box.

Underneath these six boxes is a set of brake cables (inners and outers), the presence of which completely mystifies me. I assume that the eTap aero set would be bought either to upgrade a TT bike (as I did) or for a new build. Neither scenario would seem to require a set of brake cables to be supplied, though no doubt they will come in useful in due course for another bike project (my TT bike has hydraulic brakes).Sadly, no Haribo gummy sweets were present.InstallationI began by fully charging the derailleur batteries. Because the front and rear derailleurs use exactly the same type of battery, if the rear runs out of juice, you could always swap in the front mech battery. The instructions provided observe that when the battery is detached, both the battery and derailleur need to be protected by the plastic parts supplied to protect the connection parts. I believe the system is activated by motion sensors, and the recommendation when transporting the bike by car is to remove the batteries to avoid unintended discharge.Installation turned out to be stupidly straightforward. In fact, the biggest hassle was feeding the blip cables through the base bars, but a little ingenuity sorted that out. Pairing the three components (rear and front mech, and the blipbox) took less than 30 seconds. On my TT bike, the wires from the blips pass through handlebar setup internally, using the pre-existing slots cut for gear and brake cables (the P5's hydraulic hoses are entirely internal). Deciding where to place the blips on the base bars and aero extensions took a few minutes, before I taped the bars. And then a test. Well, the controls worked well, though the rear mech wasn't quite aligned with the sprockets. A quick perusal of the manual showed how to fine-tune that. Then all was done.You might be wondering about that alarming sticker on the front mech. I can only assume that refers to the funny little wedge pieces that apparently brace the mech against the seat tube of the frame. It's not obvious why these are needed, but I complied.UsageSo, I'm using a Campagnolo Record chainset with TA rings, SRAM mechs, SRAM chain and Dura-Ace cassette. Does that combination work? Well, on the basis of riding out to a 10 mile time trial, riding the event, and riding back, I'd say so. Shifting was very smooth (I might even suggest too smooth - I did miss the positive click of my old Dura-Ace levers), and I found the usage of the blip switches really very intuitive. I made no inadvertant gear changes, though to be frank I didn't do many changes with the front mech.Battery life presumably depends on the number of shifts you do. The blipbox uses a CR2032 cell, which i supposed to be good for over a year. Each derailleur has a rechargeable battery supposedly good for 1000km/60h of use. The system uses the same battery design for both mechs, so they are interchangeable.In the week following my first ride with the system, I revisited the mounting of the blipbox. Its garmin mount section is threaded for a screw, so I drilled the top plate of my aero bars, and fix it in place that way. It's a fair bit neater than the elastic bands!I rode the system in the NBRC Hardriders club '20', and did have some hassle with my mongrel transmission - the chain didn't want to seat properly on the inner ring. Hopefully I can sort this out without resorting to a new chainset.Worth it?Well, it's nice. It works well (faultlessly so far on my limited riding to date). I now have 11-speed on this TT bike. It doesn't require any guddling around persuading cables to pass through the frame. I am pleased with it. But does it represent a major performance improvement over the old style mechanical Dura-Ace it replaced? Well, I'm not sure, though I very much like having a second set of controls near the brake levers. I can say, though, that were I to spec out a new road bike, a SRAM eTap group would be high on my "to buy" list.Longer term, I'll do an update on performance (part 2!).
