I bought 68X107 for Miche primato crankset instead of a Miche BB which would have cost 3800. It's working smoothly without any problem.
Way better than my oem BB. Runs smooth and well balanced.
It's very well Ballanced & smooth
Perfect fitment for my bike.
Choose the right size rest you are good to go. Nothing to worry atleast for 5000 Kms
