C-BEAR REPLACEMENT INNER SLEEVE FOR BSA DUB GEN2 CERAMIC BOTTOM BRACKET (PROTECTIVE SLEEVE)
This original C-Bear replacement inner sleeve (dirt shield/sleeve) was developed specifically for C-Bear Generation 2 (Gen2) BSA bottom brackets using the SRAM DUB standard (28.99 mm axle diameter). It is installed in the center between the two bearing cups inside the bottom bracket shell and effectively protects the crankshaft and the inside of the bearings from dirt, moisture, and the ingress of foreign objects.
Furthermore, the sleeve serves as a reliable shield against damage from brake lines, shift cables, or e-bike cables routed in the bottom bracket area, which could otherwise be worn down by crank movement. It is ideal as a replacement part in the event of loss, damage, or for completing your C-Bear BSA DUB Gen2 bearing system.
Note on scope of delivery: This is strictly a replacement inner sleeve as pictured. Delivery does NOT include bearing cups, cover caps, or spacers!
