CX 36/46 MEGAEXO to Compact 34/50
Ive just got a Colnago World Cup and it comes with a FSA 36/46 Megaexo and I would like to change it to a Compact 34/50 but I could live with a 36/50 set up if that is possible. Do I just change the big ring to the 50 or the whole Chainset. Also Could the Megaexo BB be changed to a BB30 set up? Any advice would be great.
