Overview

The right GXP non-drive side fit in the Enduro MR 22378 LLB-E

The Enduro MR 22378 LLB-E ABEC-3 Sealed Bearing - GXP | 22x37x8mm is the direct-fit replacement bearing for the non-drive side cup of a SRAM GXP bottom bracket. Its inner race extends past the outer race to 11.5mm wide, which matches the stepped-down end of the GXP crank spindle. When that side of the bottom bracket starts to feel rough or loose, this is the bearing that goes back in. Install it with the extended inner race facing in, toward the center of the frame.

ABEC-3 is the most economical bearing grade Enduro makes, and it is still built tough. You get Grade 10 chromium steel balls, 52100 high carbon chromium races hardened to R-62, riveted steel retainers, and LLB type silicone seals to keep grit out. It measures 22mm inside, 37mm outside, and 8mm across the outer race, and it is sold individually. It is the right part for riders and mechanics servicing a GXP bottom bracket who want a correctly sized non-drive side bearing.
