My girlfriend is 5’2 and is riding a 49cm 2021 trek checkpoint SL6. Her bike fit needs some work and I think some shorter cranks either 155 or 160mm would be beneficial. Her bike currently has Shimano GRX RX810 170mm cranks.
I’m not too familiar with GRX, not even sure what bottom bracket this bike uses. If anyone has recommendations (ideally not too expensive) for replacing the crank arms/ full crank set I would greatly appreciate it!
