We've been working on my son's hillclimb bike this evening. The seatpost has an annoying habit of going down; it's supposed to be for a 31.4 seat tube, but measures for a 30.8 despite what's printed on it. And no, we're
not using another as the seatpost weighs only 90g.
Tried tape. Didn't work. Tried non-slip tape. Too wide. So we used masking tape, which
has worked.
Then, as I'm putting the wheel covers on, a front spoke goes
. It needed a replacement front tub anyway, but it looks like the allloy spoke nipple's snapped. I
really hope it's not a bonded one as the wheels are 1100g.
I'll use the time it's out of storage to swap the shifter hoods for heat-shrink plastic (should save 40-50g) and remove the left Di2 shifter internals and non-brake levers (saving 20g or so), with the aim of bringing the bike down to 5.3kg.
The joys of working with an ultra-light bike
