I have an older Giant Cadex 980C with a shimano 105 7 speed drivetrain. I want to put a compact crank on this bike. Is it possible? If so, what do I need to look for when purchasing the cc? I assume some will and some wont' work. Will I need a whole new drive train or can i just retrofit the cc? What info am I not considering that I should?
Thanks for your feedback!
