Actually, all "compact double" refers to is the 110 mm bolt circle. Although these usually come with 34/50 rings, there's nothing stopping anyone from putting a smaller big ring on such a crank. 34 T is usually as small as rings come in this size (although there may possibly be a 33T). "Mountain double" obviously refers to a smaller bolt circle -- what used to be called "microdrive". -- You received this message because you are subscribed to the Google Groups "RBW Owners Bunch" group.
