Upgrade a BB30 or BB386 bottom bracket with Enduro's XD-15 ceramic hybrid. Enduro designs these to get smoother with use rather than slower, and backs them with a Limited Lifetime Warranty against corrosion and wear.

Highlights

• XD-15 ceramic hybrid: cryogenically treated nitrogen steel races with Grade 5 silicon nitride balls
• 30 x 42 x 7mm radial bearing, ABEC-5
• Upgrade replacement for BB30 and BB386 cranksets with 30mm spindles
• Dual-lip labyrinth (LLB) seals over a 90% fill of Kluber NBU52 grease
• Limited Lifetime Warranty against corrosion and wear

Why XD-15

Most ceramic hybrid bearings are at their fastest on day one and slow down as their steel races wear. Enduro's XD-15 races are a corrosion-resistant, cryogenically treated nitrogen steel, and Enduro says the hard ceramic balls polish them smoother as the bearing wears in. Deep-groove raceways make room for the largest possible balls, spreading load over a bigger contact area for performance and longevity.

Seals and grease

Dual-lip labyrinth (LLB) seals ride in a micro-groove to keep water and grit out, and hold in a 90% fill of Kluber NBU52 grease that resists washing out.

Compatibility & fit

Enduro lists this bearing's most common use as an upgrade replacement in BB30 and BB386 bottom brackets running cranks with 30mm spindles. Check your existing bearing is a 6806 (30 x 42 x 7mm) before ordering. Bottom bracket installation is a separate workshop service; press-fit bearings need the right press tools to go in square, and our workshop can fit them for you.
