In which I grab the soldering iron and splice together wires and plugs to place the 'brains' of the eTap system deep in the bowels of my TT frame!

Earlier this year, I travelled to Wales for a Team Grumpy reunion of sorts, in the form of a 2-up team time trial. This was a ‘sporting course’, so I took along my Cervelo P3, currently equipped with 11-speed eTap Red gears. By the time the bike had been in and out of the car a few times, one of the blipbox ports had stopped working (this happened before, with the P5).
