2003 Campy Chorus - 10sp(13-29) and 39/53 CRings - exploring conversion to a Campy triple with least amount of new parts - Campy has a description of their "Comp Triple" in their '14 catalogue and it mentions 10 speed kit, long cage RD, & specific FD.
I'd also be interested in buying a smaller CRing from Specialites as pointed to by Alienator in another post .
Seems like I'd only need the drive side crank and I could continue to use my current 10 speed rear cluster - however, don't know if you can only buy the drive side crank ?? probably not .
And so worse case I'd need a new crankset, front & rear derailleurs & an additional chain ring & could continue with my rear cluster & BBearing - assumes the triple would work with my tapered BBearing ?? - does that seem correct or would I need other new components, e.g. brakes/shifters ??
