Top Fuel cracked, big up Trek who gave me a Superfly for a nominal cost as replacement, bits all sold, built up with lighter bits.
Looks like this:
Gave it a good 4 hour blast round the Surrey Hills with Gee yesterday, tis good. Impressed with the 29er-ness, didn't miss the rear suspension at all, bags of grip, would've been sliding around a bit more on 26" Rons. Was long enough to scuff the paint in various places though, much helicopter tape was applied earlier.
Light Bicycle hookless rims seem good, tyres went up perfectly, and I didn't suffer an ignominious death of exploding tyres and latex at the first corner. Running about 25psi.
XX1 just worked. More chain noise on the stand than I'd expected, but outside it was flawless, Grip Shift was a bit odd after 5 years of triggers, but the shift is really positive. 32t ring seems about right. Left the chain long so I can go for a bigger ring.
Got a new Mt Zoom flat bar on order to get the front end a bit lower, probably combine with a shorter (90mm) stem. Ought to get it below 19lbs somehow, perhaps with Thunder Burt tyres in the summer!
