Flies & Bikes is a website/blog that I started some years ago. Initially I was writing about my interests in Science and my hobbies which include cycling (touring and racing) and tech stuff. At the time I was a University academic, but as my time available to blog waned, the focus shifted towards cycling and tech, then eventually it entered a rather fallow period. 

Along the line, I transitioned the blog from Joomla to Wordpress. I've now reverted it back to Joomla - in doing so, I dropped various comments on blog articles (there weren't very many) as the transition, while automated, leaves quite a lot of manual rearrangement to be done.

I've been using Zwift regularly since April 2020, when I was building back from being an 'early adopter' of Covid-19. In all that time, I've not raced in Zwift, and I've only very occasionally ridden with friends on Zwift.

Until now.

Part 3 of this series is somewhat delayed by Christmas and associated shenanigans such as the traditional Christmas Cold, which really flattened me for a couple of weeks.

In Part 1 I described the hardware I use for cycle training indoors. In Part 2 I’ll describe the principal software package I use for indoor training, TrainerRoad. Part 3 will cover the other software I use, and Part4 the software I use for monitoring my progress (with some hardware comments).

There's a wide variety of apps out there for use with smart trainers. For some of these I'll only give a brief description in Part 3, while others I'll keep my comments very brief as I haven't used them extensively enough to form a valuable opinion.

This is the first in a short series of posts in which I discuss my approach to training for cycle time trials. I find road cycling to be unsuitable for structured training sessions other than extended endurance sessions, due to a combination of climbs and descents (albeit pretty small around here), junctions, traffic lights and of course motor traffic. The exception to that would be the evening 10 mile time trials the club offers through the season, which provided an opportunity for riding at a high sustained pace for 20+ minutes.

In part 1, I’ll give a bit of background to the kit I use.

Support for Joomla version 3 ceased in August this year, and I'd been working on ensuring the three Joomla sites I maintain were upgraded to version 4 in advance of that. What I realised in doing that was the enormous amount of cruft I'd accumulated over the years, especially with the North Bucks Road Club website. One of the issues is always that of finding a sympathetic template, particularly where user access on mobile devices is concerned.

In which I test (and implement) some alternative wiring possibilities for SRAM eTap gear shifters

The SRAM eTap Aero groupset was released in 2015 with a version aimed at road bikes where the gear change controls were switches in the brake levers, and which communicated with the front and rear derailleurs via a proprietary wireless signal. For time trial bikes, the eTap aero was released, where switches mounted on the aero bars were wired to a "blipbox", which wirelessly relayed commands to the gear mechs. Typically, one would set up a pair of switches (the "blips") on the base bar and a second pair of switches (the "clics") on the ends of the aero extensions. The blipbox has four sockets, two for upshift and two for downshift - each clic or blip switch is connected via one socket. The blipbox also has some buttons for shifting. The annoyance there is that the size of the blipbox makes it difficult to tuck it away in the time trial frame.

In which I do yet another bout of TT bike fettling, this time to address the front end clutter.

The (possibly mad) plan for the P3C handlebar

Some months ago, I’d bought a secondhand 3T Aduro base bar (the same as came with the P5-Six). The original intention had been to replace the base bar on the P5. Unfortunately the four bolts holding the low extension/armpad mount to the replacement base bar were themselves seized. This appears to be a bit of a problem with these bars - my P5 has a set of Aduro bars in the low position, and one of the four screws holding the stem top plate was seized and I was never able to extract it.

This book is a nicely presented tome all about the American cycle pioneer Jobst Brandt. I'd long been aware of Brandt not only because I bought a copy of his excellent book on the spoked bicycle wheel (The Bicycle Wheel), which includes guidance on wheelbuilding, but though reading his old USENET posts on matters pertaining to bicycle technology. Many of those old posts have been preserved at Sheldon Brown's website (itself maintained some years after Brown died in 2008). Brandt was strikingly forthright and not shy in making his views known through these early internet posts. However, I'm getting a little ahead of myself here.

Hed H3 wheels are  probably Team Grumpy’s go-to wheel - they are pretty close to being indestructable (but not invulnerable) - they aren’t likely to go out of true as there aren’t any spokes to break or lose tension. 

In use, I’ve always found them to handle well except in the windiest of conditions (see for example the 2018 edition of the Duo Normand when I ended up using a regular spoked wheel). In comparison to very deep rimmed spoked wheels, they seem to be more of an all-rounder aero wheel for time trialling.
