My wife just picked up her new Specialized Roubaix Pro with FSA cranks and Shimano Ultegra and Dura Ace Drive train. The Shifts are not smooth and chain drops have occured a few times on first ride. We took it back for adjustments and after a few miles it's happening again. could the FSA cranks spacing and such be incompatible with the Ulteg/Dura ace duraileurs?
Thank you
