if you're riding a bike with 650c wheels because you NEED to, then you should probably be on 160mm or 155mm cranks. which means cobb, rotor, infocrank, most likely.
Dan,
Has a factor in the riding of 650c bikes also not been the issues surrounding gearing?
1) You shorten the cranks substantially therefore to to maintain the same pedal force as longer cranks one needs to reduce size of chainring
2) Yet the loss in wheel circumference demands an increase in chainring size if the desire is to maintain same rpm at same speed (which can be a function of physiology and fitness)
A solution IMHO might be if SRAM did an XD cassette with a road like spread e.g. 10-26
Interested in your thoughts....
