Details

• Ultra-Smooth Ceramic Bearings: Equipped with high-precision ceramic ball bearings that offer significantly lower friction and rolling resistance than standard steel. Experience buttery-smooth rotations, enhanced power transfer, and maximum pedaling efficiency.
• Precision T47 Compatibility: Specifically engineered for frames with T47 threaded bottom bracket shells and 86mm widths. This adapter allows for a seamless transition from a T47 frame to 24mm spindle cranksets, such as Shimano Hollowtech II

• Silent & Secure Threaded Design: The threaded-locking system ensures a rock-solid interface with your frame. Unlike traditional press-fit systems, this design eliminates annoying creaks and mechanical noise, ensuring a quiet and stable ride.
• Superior All-Weather Reliability: Ceramic material is naturally resistant to corrosion, wear, and heat. Combined with a dual-seal system to block out water, dust, and grime, this BB ensures long-lasting performance in the harshest riding conditions.
