I just bought my first new bike in about ten years, and naturally it has a crankset with external bearings, Shimano SLX in this case. Are these Shimano bearing sets interchangeable across component groups? That is, will LX/Ultegra/XTR/Dura-Ace/SLX all work interchangeably? I ask because I would like to have a spare set up bearings and the place I typically buy this stuff only has Ultegra bottom brackets in stock. I’m guessing they would work fine, although they also carry a Chris King bottom bracket set with adjustable and replaceable bearings that is really tempting.
Yes, Ultegra or any other Shimano Hollowtech II external bearing set will work fine.
