Quality product
Upon opening, the Shimano XT bottom bracket looks like a quality piece. I never had any problems with the three Shimano bottom brackets I have used in the past 13 years. Two of the cheaper Shimano bottom brackets were installed in the completes I had purchased back in 2011 and 2012. On a custom build, I used an XTR. There was no discernible difference, so I went slightly cheaper with the XT bottom bracket this time around. I have not used it yet, as I am waiting for my Stanton frame to come in from the UK. But I have confidence that it will pair perfectly with my new Race Face Aeffect R crankset.

Works with GRX crankset
- Familiarity:
- I've used it several times
As I went to put it all together and realized my GRX cranks suggested an Ultegra BB rather than this XT BB I got. After talking to a few LBS folks I know, they reassured me they're pretty much the same thing. All together with 100 mi. in it works perfectly!
