Shaft diameter less than 24 mm, broken part
"The diameter of the plastic sleeve that protects the bearings and into which the crankset is inserted is 23.9 mm; it's impossible to assemble it without breaking this plastic part. . . I wanted to buy a French product, but in the end the "SHIMANO BB-RS500 TIAGRA / SORA BSC (188724) Bottom Bracket" is a better fit. It was for a GRX 600 crankset with a 24mm axle."
