You have options if you're trying to run a 24mm spindle crankset on a BB92 frame, but the Race Face BB92 Bottom Bracket Adapter is one of your better options. Whether your favorite crankset comes from Shimano or Race Face, it doesn't matter, because either way, you're covered. At the heart of this adapter is a pair of high quality, user serviceable bearings. The precision machined aluminum cups are designed to stay put, instead of rocking and creaking like lesser cups can. And the plastic inner sleeve protects the bearings from whatever liquids might leak into your bottom bracket shell. The Race Face BB92 Bottom Bracket Adapter is available in one size and one color.
