Another topic - kind of 41ish but for the National Hill Climb Championship in Aug. This is up Pikes Peak in in my son's back yard. They have a U19 div (??). Don't know which he will do and kinda depends who shows up. I'm posting info to his competitors as well :-)
I'm rebuilding the MASI. The BB is a PF30 that we originally had press fit cups for. I ordered WheelsMfg ceramic BB. the purpose is to get a 12# ish real performance hill climbing bike. The goal is as stiff and light as I can. So many weight weenie things will be rejected just because they are too fragile. This should be fun. Economics matter too, to what degree - don't know. I am tempted to go low profile lighter wheels but his 50mm 25mm width with those 25 FMBs build out to about lightest in the world (in that config). Going <30 profile, 20 width and 22mm Veloflex record would save 600g total and cost $3K, so not so sure on that one. I like the rolling of the FMB silks that I get made with different tread. I'm sticking with Shimano cranks. Likely 9000 as they cost 1/2 of the new stuff. Going compact 50/34 from his 52/39 and 175 over current 172.5. Wondering if I should go 177.5. Definitely ceramic BB, hubs, and likely pulleys.
Switching out brake stuff for Power Cordz.
So looking for real racing weight weenie type stuff/suggestions.
