Compatibility & fit

Sold by size — match 12x26x8mm (ID x OD x width) against the bearing you're replacing. This size is used across several positions (bottom bracket, hub, pedal or pivot) depending on the standard it's built into — confirm it matches the position you're replacing before fitting.

Black Bearing covers manufacturing defects on its bearings for the period stated by the distributor at the time of purchase; wear from normal use, incorrect fitment or contamination is not covered. For warranty support, return the product to Tune Cycles and we'll manage the claim with Black Bearing's Australian distributor.
