Shimano M770 Hollowtech II Bottom Bracket

BikeRadar verdict

4.5 out of 5 stars

"Shimano’s revised bottom brackets are the best value around"

Thursday, March 5, 2009 10.00am By

Shimano’s original bottom brackets were legendarily bad, but they’ve cleaned up their act to become one of the best value options around. 

The bearings are a lot more secure, so there’s much less chance of crank wobble. Much better sealing means we’re now seeing units last for months in the worst conditions, making them a decent investment.

The negatives are that the cup threads are a bit short for using with bottom bracket mounted (non-ISCG) chain devices, and they won’t fit Truvativ cranksets.
