BK-6100 - 61.5mm Enduro OSBB Road TorqTite cup spacer kit

This seal is the narrow version that is required in most Enduro TorqTite and T47 GXP BBs with MR 2237 and MR 2437 bearings and GXP reducers, though the SE MR 2437 will also work with fit over the GXP bearing reducer.

This dual-lip silicone seal presses directly onto the inner race of our 28mm x 37mm XD-15 Corsa bottom bracket bearing to provide a perfect seal onto our 24mm BB TorqTite cups.

This dual-lip, light-contact silicone seal presses directly onto the inner race of our 30mm x 42mm XD-15 Corsa bottom bracket bearing to provide a perfect seal onto our BB30 size BB cups.

This light-contact silicone seal is designed to work exclusively with Trek BB90/95 bottom brackets and cranksets with 24mm spindles.
