61806/29 LLU/LLB BB - ABEC-5 Radial Bearing (C3 Clearance) - 29 x 42 x 7mm
An ABEC-5 Radial Bottom Bracket bearing contains 52100 High-Carbon Chromium alloy races matched with grade 5 Balls and a 90% fill of high-pressure, water-proof grease. Specifically designed for bicycle applications, these bearings feature an LLU/LLB seal combination. The outer-facing grey LLU seal aims to shield against water or dirt, reducing contamination, while the inner black LLB seals, with less drag, maintain the grease effectively.
This bearing is frequently used as a direct substitute for BB30 and PF30-type bottom brackets compatible with SRAM DUB cranksets.
