Close fitting on the chain side
on 25 January 2014
Bought this to replace an old Shimano 68mm outer, 113mm axle length bottom bracket. Quality is OK, but (unlike original) this axle is not symmetrical. On the Crankset (chain / right) side, the axle is about 3 mm shorter than the original, and so on the left side, the axle is 3mm longer. Shouldn't have been a major issue, but I also bought Shimano Tourney FCM131 Crankset where the chainrings are also about 3mm to the left. With the smallest chainring 6mm closer to the frame than previously, I'm unable to use new bottom bracket and new chainset at the same time. Quality OK other than this offset.
