Paperclip Posted January 18, 2016 Report Share Posted January 18, 2016 Worth just working out which side had failed and checking the bearing fitment. This happened to a friend of a friend and his frame was warped around where the bearing pushes in (from new) with the rear of the bottom bracket (chain yoke) weld had misshaped it. He alsobelieves with riding that the flex was making the bottom bracket area worse. Quote Link to comment Share on other sites More sharing options...
Mark W Posted January 18, 2016 Report Share Posted January 18, 2016 You can always put a bit of Locktite 271 "Stud and Bearing Fit" around them to give them a solid seat in there too. Quote Link to comment Share on other sites More sharing options...
crilin202 Posted January 22, 2016 Report Share Posted January 22, 2016 My because color also used to eat BB bearings fairly quickly. I used to get mine from Wych Bearings. They are cheap and cheerful. Quote Link to comment Share on other sites More sharing options...
