The SD Spinning BB386 bottom bracket is a 100% precision-engineered drivetrain component designed for modern BMX race frames with 46mm ID shells, such as the Meybo HSX. This bottom bracket is celebrated for its ultra-low friction "spinning" characteristics, ensuring your crankset rotates with near-zero resistance during the most critical phases of the race. By providing a rock-solid, press-fit foundation, it eliminates lateral flex and maintains perfect chainring alignment, ensuring 100% of your power is transferred to the rear hub as you pull on the bars and grips for the holeshot.

• Compatibility: Frames with a 46mm ID BB386/PF30 bottom bracket shell
• Axle Interface: Available in versions for 24mm or 30mm spindle cranksets
• Performance: High-precision sealed bearings for 100% smoother "spinning" efficiency
• Construction: CNC-machined aluminum cups designed for a 100% stable, creak-free fit
• Durability: Integrated dust shields and o-rings protect against track-side debris and moisture
• Benefit: Optimized for the explosive torque and high-RPM requirements of podium-level racing
