Hi all,

Having just installed a SRAM BB86 GXP PressFit Bottom Bracket I noticed the drive side bearing is running rather tight and you can hear the balls scraping the bearing side wall. The cup did go in rather tight into the frame. Do I need to sand off some of the cup so that the frame can better house it?




  • Sanded of some of the drive side cup and now the bearing slips in a lot easier. Still a tight fit but not more tight than the non drive side. It helped a bit. Still a bit of noise from the bearing but it is definitely running smoother. Could it be a bad bearing?
