The Blackbearing B3 Bottom Bracket Bearing Kit for Truvativ GXP STD is engineered to provide flawless power transfer, smooth rotation and long-lasting performance. Designed specifically to meet the high-load demands of bottom bracket assemblies, it delivers consistent efficiency ride after ride.
Complete Dual-Bearing System: This kit includes two precisely matched bearings — MR-22237-2RS (22.2x37x7/11.5) and 2437H8-2RS (24x37x8) — ensuring perfect fitment and compatibility with Truvativ GXP STD cranksets. Together, they maintain optimal crank alignment and eliminate unwanted play.
Stainless Steel Construction for Durability: Part of Blackbearing’s premium B3 stainless steel series, these bearings resist corrosion and wear even in wet or muddy conditions. The material’s superior hardness ensures long-term reliability and smoother pedaling across thousands of kilometers.
Double-Sealed for Maximum Protection: Each bearing features a 2RS double-seal design that effectively shields against dust, water and contaminants. The seals preserve internal lubrication, keeping the rotation smooth while minimizing maintenance needs.
Designed to meet the precise tolerances of Truvativ GXP systems, the Blackbearing B3 Bottom Bracket Bearing Kit ensures efficient energy transfer, reduced friction and dependable performance — perfect for riders seeking precision and longevity in every pedal stroke.
