DUO Brand R2 Rear Wheel

Product Overview

The DUO Brand R2 Rear Wheel is engineered for competitive BMX racing, prioritizing speed and lightweight performance. Available in disc-specific and rim brake configurations, each wheel features a precision-laced hub, aerodynamic rim design, and stainless steel spokes. Built to compete at the highest level while delivering durability and reliability.

Key Features

• R2 120 disc or standard hub – Lightweight, sealed bearing hub optimized for fast spinning and minimal friction. R2 120 designation indicates 120mm rear axle spacing, standard for BMX. Sealed bearings resist dirt and water intrusion, extending service life and reducing maintenance.

• R2 Aero or standard rim design – High-dollar carbon-fiber aesthetic with the durability of 6000 series aluminum. Aerodynamic shaping reduces rotating mass and improves acceleration. The rim profile balances strength with minimal weight for racing applications.

• 32mm or 32.5mm rim width – Wide enough to support modern BMX tires and provide adequate spoke tension while maintaining minimal rotational mass. Wider profile improves lateral stiffness during aggressive racing maneuvers.

• 6-bolt disc brake pattern (disc version) – Standard rotor mounting system compatible with modern hydraulic and mechanical disc brakes. Allows precise rotor alignment and secure attachment.

• Brake surface rim (non-disc version) – Smooth machined braking surface provides consistent pad contact and modulation for rim brake systems. Compatible with standard U-brake and caliper brakes.

• Stainless 14-gauge spokes with brass nipples – Corrosion-resistant stainless steel spokes resist rust and maintain strength. 14-gauge provides adequate tension and stiffness. Brass nipples resist seizing and allow spoke tension adjustment without stripping.

• 16-tooth cog – Standard BMX rear cog providing appropriate gearing for racing. Works with 1/2 x 1/8" chains.

• 15mm axle – Standard BMX rear axle specification fitting all modern BMX frames.

• Nylon HP rim strip included – Protective strip between rim and inner tube prevents spoke nipple punctures. Nylon construction is durable and lightweight.

• Lightweight, fast-spinning design – Optimized for BMX racing. Minimal rotating mass improves acceleration and reduces energy loss during racing efforts.
