Box Three Pro 10mm Front 36H Hub Black

Product Overview The Box Three Pro is an affordable yet feature-rich 36-hole front disc hub engineered for BMX racers seeking reliable performance with modern disc-brake integration. The 120-tooth engagement system and 4-pawl design deliver crisp power transfer—beneficial for front-wheel drive applications. Precision sealed bearings and cold-forged aluminum construction provide durability across racing and training. Available with or without 6-bolt rotor; weighs 444g with disc or 270g without.

Key Features

• 120-Tooth Engagement System – High-ratchet count provides immediate engagement with minimal lag; delivers responsive power transfer on front wheel
• 4-Pawl Design – Four-pawl engagement system ensures redundancy and consistent ratcheting across extended riding sessions
• 6-Bolt Disc Rotor Compatible – Engineered for modern 6-bolt rotor standards; enables integration with hydraulic or mechanical disc-brake systems
• Precision Sealed Bearings – Sealed cartridge bearings eliminate water and dirt ingress; reduce maintenance and extend hub life
• 6061-T6 Aluminum Hubshell – Lightweight yet durable aluminum resists corrosion; maintains strength without adding excess weight
• Chromoly Steel Driver – Cr-Mo construction resists bending and cracking; provides superior strength for racing applications
• CNC-Machined Components – Precision machining ensures exact tolerances and perfect bearing alignment; reduces play and maximizes smooth operation
• Available With or Without Rotor – Flexibility to purchase hub alone (270g) or complete with 6-bolt rotor (444g); customize based on setup
• Anodized Finish – Protective coating resists corrosion; maintains clean aesthetic through extended use
• Lightweight Design – Front hub construction prioritizes minimal weight while maintaining strength; 270g base weight competitive for racing

Compatibility and Ideal Use Cases

• Fits: 36-hole front wheel builds on BMX frames with 10mm bolt dropouts or 20mm thru-axle (with conversion sleeve); disc-brake equipped frames
• Disc Rotor Compatibility: Any 6-bolt rotor; standard size for modern BMX disc brakes
• Best For: Budget-conscious BMX racers with disc-brake bikes; riders seeking reliable engagement and responsive front-wheel performance
• Ideal Riders: All skill levels; competitive racers on a budget; riders prioritizing disc-brake integration on front wheel
• Wheel Building: Requires 36-hole rim, spokes, and nipples to complete front wheel assembly
• Not Recommended For: Riders requiring ultra-lightweight construction; those needing specific engagement systems beyond 120-tooth standard; non-disc-brake setups

Rotor Options

• Without Rotor: 270g hub only; allows selection of preferred rotor separately for weight or performance optimization

Performance Notes The 120-tooth engagement system delivers crisp, responsive power transfer on the front wheel—beneficial for riders using front-wheel drive applications or seeking consistent hub performance across all wheel positions. Four-pawl redundancy ensures consistent engagement through extended riding and racing.

Durability and Value Chromoly driver and aluminum hubshell provide excellent strength-to-weight ratio at affordable price point. Sealed bearings require no regular maintenance. CNC-machined components ensure precision tolerances and long-term reliability across racing and training use.

Maintenance Notes Sealed bearings need no regular servicing; hub lifespan extends across multiple racing seasons with minimal care. Check bearing play periodically; smooth rotation without wobble indicates proper function. If purchased without rotor, verify rotor compatibility and bolt tightness before riding.

Weight Advantage At 270g without rotor, the Box Three Pro front hub offers competitive weight for racing applications. With rotor at 444g, total front wheel weight remains efficient for speed-focused builds. Rotor selection can further optimize weight if ultra-lightweight options are prioritized.
