Coated bearings utilize the highest quality CeramicSpeed ceramic balls, running on hardened-steel races with a 3-micron thick metallic coating making the races corrosion resistant, harder and smoother, increasing service life and reducing friction.

In the box:

• 2 CeramicSpeed Bearings
• 2 dustcovers
• Spacer tube
• 1 x 3mm spacer
• 2 x 1mm spacers
• 10ml syringe of CeramicSpeed Long Life Grease
• Sticker sheet

Tech data:

This product has a unique design specifically for SRAM DUB 28.99 cranks. With native fit frame interface and no plastic adapters or excess spacers. This design features a custom integrated dustcover for maximum durability.

CeramicSpeed standard Bearings typically have frictional drag of 0.3-0.4 watts per set. That means an average 75% drag reduction compared to standard bottom brackets. The hardened-steel races feature CeramicSpeed Balls that are 100% smoother and 15% harder than the ceramic competition. The CeramicSpeed Bearings last at least three times longer than other bearings.

Coated Bearings drop friction further and increase lifespan to applying a coating to the races. The coated races see a 50% drag reduction and an improvement in bearing life of 60%.

LongLife Grease comes installed, but can be changed for lower drag All Round Grease, which is fine for less extreme conditions.
