I was wondering if anybody could help me with a question. I have been getting cramps at about the 40-50 mile mark in my rides.This is a problem I have had for a while. I have tried eating, hydration and all of the other things that one could try to eliminate this form happening. In March I purchased a new Look 585, it was fit by the shop. When I asked him about the cramping issue ,he said he noticed that my cadance was a little on the low side and that I should try to get it into the 90s.My question is would changing me large chainring from a 53 to say a 52 or 50 help me. I know FSA has a 50 that works on a 130mm pattern, and since that is the crank I have I was thinking of giving it a try. Anybody hace any thoughts.
