The Excess Mini Expert 28H Front Hub is a high-performance, lightweight front hub engineered specifically for BMX racing. It is a premier choice for younger riders (Mini, Junior, and Expert classes) who require a component that balances spinning efficiency with structural durability without adding unnecessary weight to the front end of the bike.

Technical Specifications

According to official documentation from distributors like Elite Cycle Imports and BRG Store, this hub features the following specifications:

• Drilling: 28 spoke holes (28H)
• Weight: 131 grams (4.6 ounces) — optimized to minimize rotational weight
• Shell Material: CNC-machined 6061-T6 aluminum body with medium flanges and straight bore holes
• Bearings: 2 ultra-smooth, precision-sealed cartridge bearings to lock out track dirt and water
• Axle: Lightweight aluminum inner axle body with alloy end caps
• Hardware: M6 inner thread tightening bolts featuring clean, anodized CNC alloy bolt caps
• Axle Size Compatibility: Standard 10mm (3/8") dropouts common on BMX race forks

Key Benefits for BMX Racing

• Reduced Rotational Weight:
  At just 131g, this hub keeps the front of the bike incredibly light. This allows younger racers to lift the front wheel over obstacles easily and manual through rhythm sections.
• Maintenance-Free Smoothness:
  Sealed cartridge bearings eliminate the need for frequent loose-ball bearing overhauls. They ensure consistent, low-friction rolling performance straight out of the gate.
• Clean Hardware Profile:
  The female bolt design using M6 internal threads keeps the outside of the fork clean, reducing the safety risk of exposed, jagged master axle nuts.
