These lower brackets are equipped with handmade coated bearings, specially developed for off-road performance that offer extreme durability and feature a unique design for SRAM DUB 28.99 cranks.
The coated bearings use CeramicSpeed ceramic balls of the highest quality, which run on hardened steel tracks with a 3 micron thick metal coating, which makes the tracks resistant to corrosion, harder and smoother, which increases the service life and reduces friction
