DUO Brand R2 Front Hub 10mm (3/8")

Product Overview

The DUO Brand R2 Front Hub 10mm (3/8") is engineered for competitive BMX racing with focus on steering precision and wheel stiffness. The high-body design increases flange stiffness for accurate wheel lacing and responsive handling. CNC-machined aluminum construction with sealed bearings delivers reliability across racing and street applications.

Key Features

• CNC-machined aluminum body – Precision-machined construction optimizes material distribution, reducing weight while maintaining structural rigidity. Clean machining ensures accurate bearing seating and minimal runout for true wheel building.

• High-body design – Increased flange height improves lateral stiffness and spoke tension capacity. Greater flange diameter distributes spoke load more effectively, creating wheels that stay true longer and respond more precisely to steering input.

• Precision sealed cartridge bearings – High-quality sealed bearings resist dirt and water intrusion, extending service life and reducing maintenance. Cartridge design allows easy bearing replacement without hub disassembly. Precise tolerances deliver smooth, responsive rotation.

• 36-hole lacing pattern with 14-gauge spokes – Standard BMX wheel lacing accommodates all rim and spoke combinations. 14-gauge spokes provide adequate tension and stiffness for wheel durability.

• Aluminum inner-axle with female bolts – Lightweight aluminum axle reduces rotational mass compared to steel. Female bolts thread into the axle, allowing secure fastening without protruding bolt heads that could catch or create drag.

• Alloy Frustrum hardware – Specialized hardware design optimizes strength-to-weight ratio. Frustrum (cone-shaped) geometry distributes forces efficiently without excess material.

• 10mm (3/8") axle sizing – Standard BMX front axle specification fitting all modern BMX frames. Also available in 20mm thru-axle for contemporary frame compatibility.

• Ultra-lightweight at 6.9 oz – Minimal rotational mass improves acceleration and steering response. Reduces unsprung weight for snappier bike feel during racing and technical maneuvers.

• Racing-proven performance – Engineered for competitive BMX racing. High stiffness and precision construction deliver winning performance and reliable steering feel.
