I have just tore down two of my bikes to tune them up for the return of Spring.
All my bikes are dressed in D/A 7800 and I have just noticed that two of my bottom brackets are different. The one on the left has a larger bearing surface. Did Shimano change the designs is one better than the other? Do I have to match the cranks to the proper bottom bracket because I am NOT sure which is which now.
Any help is appreciated,
