Enduro Bearings 6805 LLB - Zero Ceramic offers an exceptional upgrade for your bike’s bottom bracket needs. Crafted with precision, this radial bearing features black oxide treated 52100 high-carbon chromium alloy races combined with Grade 5 Silicon-Nitride ceramic balls. The ceramic balls, filled to 90% and paired with high-pressure, waterproof Kluber Isoflex NB52 grease, dramatically reduce friction and wear by eliminating steel-on-steel contact. This means smoother rotation and a longer lifespan for your components, even under demanding conditions.
Designed with dual-lip, light-contact labyrinth seals (LLB), these bearings provide superior protection against dirt and moisture, ensuring your ride stays reliable and maintenance intervals are extended. Ideal as a direct replacement for Shimano external cup bottom brackets using the plastic bearing insert, it delivers enhanced durability and performance without compromise. The black oxide treatment not only resists corrosion but also guarantees worry-free performance across seasons.
Part of the Enduro Bearings line, this ceramic-hybrid bearing stands out with its deep groove races that accommodate larger balls for improved load distribution and longevity. Whether you’re upgrading your wheels, hubs, or hub spares, this bearing is engineered to meet the demands of serious cyclists seeking robust, efficient components. Explore other components and wheels & tyres from Enduro Bearings to complete your setup.
Can I use this bearing without the plastic Shimano bearing insert?
While this bearing is designed to work with the plastic insert, if you prefer to avoid it, the MR 2437 bearing is the recommended alternative.
What makes the ceramic balls better than traditional steel balls?
The Grade 5 Silicon-Nitride ceramic balls reduce bearing wear by eliminating metal-on-metal contact, resulting in smoother operation and longer bearing life.
