CeramicSpeed SRAM DUB Bottom Bracket | Pressfit, 28.99mm Spindle
Product Description:
Maximize drivetrain efficiency with the CeramicSpeed Bottom Bracket for SRAM DUB. Built around the 28.99 mm DUB spindle standard, this bottom bracket delivers exceptional durability, ultra-low friction, and long-lasting performance, while minimizing contamination through an integrated dust cover. Hand-built CeramicSpeed bearings ensure smooth, efficient power transfer from crank to frame, making every pedal stroke count.
Engineered for precision, the bearings are 100% smoother and 15% harder than standard ceramic competitors, running in polished races that reduce mechanical drag by up to 75% compared to typical bottom brackets. The bearings are filled with All Round Grease for general use, with optional Race Day or Long-Life greases for low-drag or harsh conditions. For extra protection, the Coated version applies a metallic layer to the races, increasing hardness by 75% and delivering superior corrosion resistance, even in wet or contaminated environments.
Installation is recommended by a professional for ITA bottom brackets, ensuring optimal fit and performance. With proper maintenance, this bottom bracket offers unmatched longevity, efficiency, and smoothness, making it a top choice for road, triathlon, and high-performance cycling.
