Product Overview

The Excess Exe mini expert 28H rear hub is a professional-grade racing hub engineered for competitive BMX racing. The 3-pawl system with 5-fin engagement and 120-ratchet cutter ring delivers maximum torque engagement and reliability suitable for full-power gate starts and aggressive racing applications.

Key Features

• 4 sealed cartridge bearings – Fully sealed design keeps dirt and moisture out; reduces maintenance and extends bearing lifespan in wet racing conditions
• 3-pawl system with 5-fin engagement – Advanced engagement mechanism maximizes contact points and torque transfer; 5-fin design increases power transmission efficiency compared to standard pawl systems
• 120-ratchet cutter ring – Large ratchet tooth count delivers smooth, precise engagement with minimal freewheeling slack; optimized for full-power gate starts without chain slippage
• ISO standard compatibility – Industry-standard hub design compatible with most BMX wheel building configurations and brake systems without adapter hardware
• Alloy axle – Lightweight construction reduces rotational mass while maintaining structural rigidity under racing stress
• 10mm axle bolts with alloy CNC caps – Precision-machined aluminum caps provide clean aesthetic while securing axle bolts; CNC manufacturing ensures exact tolerances
• Alloy driver with chromoly spacers – Lightweight driver with chromoly reinforcement spacers (1x 1mm, 1x 0.5mm) optimizes stiffness and engagement durability
• Alloy lock ring – Secure driver retention without weight penalty from steel alternatives
• Shimano-compatible rear cog standard – Accepts Shimano-style, Excess, Elevn, and other standard BMX rear cogs; eliminates proprietary cog requirements
• 28-hole spoke count – Standard BMX wheel spoke configuration compatible with most rim and building specifications
• Professional-grade engineering – Designed specifically for competitive racing where engagement reliability and torque transmission matter
