I prefer the standard 53/39 crankset, so how easy is it to swap that out? Do I need a different derailleur or bottom bracket? I'm sure it can physically be done, but I don't know if it makes sense to take a brand new bike and already have to replace several parts.
Thanks!
Depends on the crankset. For example an external bb, 7900 crankset can be swapped between the "compact" version and the non compact version. BB remains the same. The cranksets itself are different - 130 bcd vs 110.
You need to give us more information.
