Description
DUO Brand R2 Front Hub 20mm
Product Overview
The DUO R2 20mm front hub is a high-flange sealed bearing hub engineered for precision wheel building and responsive steering. The CNC aluminum construction with sealed cartridge bearings provides smooth, low-friction rotation while the 20mm thru-axle design delivers secure front wheel attachment across street, park, and trail riding.
Key Features
- High-flange CNC aluminum body – Increased flange diameter and height create lateral stiffness for accurate wheel building without spoke bend or misalignment; precision CNC machining ensures consistent spoke hole positioning
- Precision sealed cartridge bearings – Two sealed cartridge bearings eliminate frequent repacking and reduce maintenance; low-friction design maximizes rolling speed and responsive steering feel
- Alloy inner axle with thread-on cones – Adjustable cone design allows bearing preload tuning; alloy construction reduces weight while maintaining adequate strength
- 20mm thru-axle system – Hollow 20mm thru-axle (included) provides secure, reliable front wheel attachment; prevents wheel slippage under braking and steering stress
- 36H spoke compatibility – Standard 36-hole configuration accommodates most BMX wheel building options without specialized spoke counts
