dhk2 said:Guess it's all a matter of degree, but saving 1-2% on a long climb or TT seems like a pretty major advantage to me. The World Master's TT was won last year with a 6 second margin, something well under 1% difference. And for me, 1% means 12 seconds ahead of my club buddies on a steep 20 minute climb with no more effort, which isn't a bad thing at all.
The motor may be 98% of the equation, but if equipment can provide a 1-2% margin, and the racer/rider can afford it, why not buy the speed?
Cuz those results are only predictable if all things remain constant when you get your new bike, which of course, with a human powered machine, cannot be predicted. The new bike 'may' give you those 12 seconds or they may not. It depends on a very unpredictable engine, a human.
Really only 4 things make a significant difference in cycling performance
-Fit-as in, does your bike fit you
-fitness-are you as fit as possible
-fat-lack thereof on you
-finesse-riding and racing smart.
All 'Fs', none of them 'frame.
