I am planning on upgrading by mid 90s Bianchi road bike. It has an 8-speed cassette, i think 11-21 and 53/39
planning on going out to 13-26 instead of spending the $ to get a campy contact crank. will also need a new chain, maybe replace the pulleys.
is there any difference between campy exa-drive cassettes and other campy models or will the exa-drive work fine with my current 8 speed drive train?
