I appreciate all the great info that this forum provides. I was wondering if anyone is riding a compact crank out there? It seems that it would be a mechanical advantage for us larger riders to be able to use a double ring and get approximately the same gear ratio's as a triple on the small chainring without having the wear and chain stretch. Any opions? Thanks in advance. I'm also about to buy a new bike and recently the Felt F4C with ultegra/dura ace mix caught my eye. The lbs has it on sale and are willing to build the same wheels that I ride now ultegra hubs with 36 spoke mavic open pro rear and ultegra and 32 spoke open pro front for 2k....anyone have any experience with Felt?
