Built with durable aluminum components and BMX-specific drivetrain, axle, and spoke configurations to meet the demands of freestyle riding, jumps, tricks, and repeated impact loads.
✓ High-Strength Aluminum Hub Shell
The AL6061-T6 aluminum hub shell provides a durable structural foundation while maintaining a balanced combination of strength and weight for BMX wheel builds.
✓ Aerospace-Grade AL7075 Aluminum Front Axle
The front hub uses a high-strength AL7075 aluminum axle, providing reliable structural support while maintaining a lightweight construction.
✓ Reinforced Steel Rear Axle
The rear hub features a robust steel axle core designed to withstand repeated impacts and high-load conditions associated with BMX tricks, jumps, and hard landings.
✓ 6-Pawl / 3-Tooth Engagement with 120 Clicks
The 6-pawl / 3-tooth structure provides 120 clicks for fast engagement response, helping deliver immediate power transfer and consistent drivetrain control during demanding BMX riding.
✓ Front 2-Bearing / Rear 5-Bearing Configuration
The dedicated bearing configuration provides stable internal support and smooth rotation while helping distribute loads across the hub structure under repeated impact conditions.
✓ 9T Single-Speed Freehub
The dedicated 9T single-speed freehub is designed specifically for BMX drivetrain applications, providing a compact and reliable interface for single-speed setups.
✓ Flexible Spoke Hole Configuration
The front hub is available in 32H, while the rear hub supports 20H, 32H, and 36H configurations, providing flexible wheel-building options for different BMX setups and riding requirements.
✓ 14G Spoke Interface
The 14G spoke holes provide a reliable interface for conventional BMX spokes, supporting secure spoke retention and durable wheel construction.
✓ BMX-Specific Axle Hardware
The front hub includes knurled washers and a 3/8″”-24T W-type inner/outer hexagonal axle bolt, while the rear hub is equipped with knurled washers and stainless-steel lock bolts for secure wheel installation.
✓ Lightweight 618g Hubset Construction
The optimized hub structure reduces the complete hubset weight to 618g while maintaining the strength and impact resistance required for demanding BMX performance riding.
