Some envy here, running 30mm tyres on a standard reach bike with approximately zero clearance to spare. Anyway
Why not use a Deda seatpost too? And you could probably shed a few grams by using RG957 calipers (although i read that the VO would be phenomenal). What cables are you considering? They can cause a night and day difference in braking and shifting. Nice QRs can also make some weight difference.
Keep us posted with your progress!
Yeah I guess might as well go Deda seatpost too, ive just always loved (and trusted) thompson stuff, id even consider going thompson stem and bars, but havent heard a whole lot about the bars yet.
for cables im thinking power cordz or aican.
I was browsing around ebay last night, and you can find cannondale hollowgram cranksets, even the sisl2 for decent prices, would probably end up costing similar to a red or record crankset.
they're definitely very light, and from what ive heard stiff too. any reason not to go with them?
