DUO Brand R2 Rear Hub

Product Overview

The DUO Brand R2 Rear Hub is engineered for competitive BMX racing with lightweight construction and instant engagement. The CNC-machined aluminum body houses four sealed cartridge bearings and a chromoly 120-point x 6-pawl cassette driver for responsive power transfer. Available in disc-specific and rim brake configurations, it includes a 15mm hollow thru-axle and 16-tooth cog.

Key Features

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

• Chromoly 120-point x 6-pawl cassette driver – Premium chromoly construction resists bending and deformation under load. 120-point ratchet with 6 pawls delivers instant engagement with minimal rotational lag (3-degree engagement). Responsive power transfer ideal for racing starts and explosive acceleration.

• Four sealed cartridge bearings – Precision sealed bearings resist dirt and water intrusion, extending service life and reducing maintenance. Cartridge design allows easy bearing replacement without hub disassembly. Four bearings distribute load across multiple contact points for smooth, durable rotation.

• 15mm hollow thru-axle – Lightweight hollow construction reduces rotational mass compared to solid axles. Standard 15mm sizing fits all modern BMX frames with thru-axle compatibility. Included with hub.

• 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.

• 16-tooth cog with lock ring included – Standard BMX rear cog providing appropriate gearing for racing. Lock ring maintains cog security under pedaling and coasting forces. Both included with hub.

• Six-bolt disc brake option – Available with 6-bolt rotor mounting for modern hydraulic and mechanical disc brake systems. Allows precise rotor alignment and secure attachment.

• Non-disc rim brake configuration – Standard hub body compatible with rim brake systems without disc mounting hardware.

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