I occasionally travel to/ride in a mountainous area (local area only has a fair amount of rolling terrain). I currently ride a Cannondale R4000si [CAAD 6] with a Cannondale Si Hollowgram crankset [39/53]. To date I have swapped out cogsets when planning for a climbing trip [to a 12-27]. My knees are weary of grinding a 39X27 @ 40rpm.
Can anyone offer any suggestions on the cheapest way to swap out my 39/53 for a compact set, like a 34/50?
Can I just swap out chainrings??
Can anyone speak to what is compatible with the Cannondale Si Hollowgram bottom bracket [The CAAD6 has an oversized BB shell and axle]??
Thanks all.
