Want to ditch my basic square taper FSA Vero (50/34) crankset on 9x2 speed Sora drivetrain (2018 Devinci Silverstone 2) in favor of 105 compact crankset. I will attempt to get one in 50/34 not to mess up gearing.
First of all because it's FSA square taper, secondly 105 is lighter and I can get it locally used in great condition.
Obviously I have to replace the crankset and BB Potentially reuse BB (RPM, Square taper JIS) and FSA crankset in my old Raleigh rebuild, but this is separate story...
Asking if it is possible, if Yes what I have to take in account when doing this. Thank you
