Built for gravel riding where tyre volume and compliance matter most, the Shimano GRX WH-RX570 650B rear wheel pairs a wide, tubeless-ready aluminium rim with a tough, serviceable hub — giving you the rolling performance of a dedicated gravel wheel without sacrificing repairability on the trail.

Highlights

• Wide 21.6mm internal rim width optimised for 38–53mm gravel tyres
• Tubeless-ready clincher — run lower pressures for better grip and comfort on mixed terrain
• Centre Lock disc interface keeps the rotor centred and installation fast
• 12×142mm thru axle for stiff, precise handling on rough gravel
• 24 straight-pull bladed stainless steel spokes for a laterally stiff, lightweight build
• Cup-and-cone hub bearings with labyrinth seals — easy field servicing
• Shimano/SRAM HG 10/11-speed freehub compatibility

Rim Construction

The 22mm-deep aluminium rim uses a welded joint and an asymmetric profile engineered to resist flex under hard cornering loads on loose or rutted surfaces. At 21.6mm internal width it sits squarely in the sweet spot for modern 40–50mm gravel tyres, allowing the tyre sidewall to open up for a more rounded, supportive contact patch. The rim bed is tubeless-ready, requiring only a tubeless tape and valve to convert.

Hub & Spoke Details

The rear hub runs on cup-and-cone bearings protected by labyrinth seals against mud and water ingress — a design that prioritises simple, affordable maintenance over sealed cartridges. The 24-hole flange accepts straight-pull bladed butted spokes laced in a 2-cross pattern, balancing aerodynamics with lateral stiffness. The standard Shimano HG freehub body is compatible with 10- and 11-speed HG cassettes from Shimano and SRAM.

Compatibility & Fit

The WH-RX570 650B rear wheel fits frames with a 12×142mm thru axle and Centre Lock disc brake mounts. It accepts Shimano/SRAM HG 10/11-speed cassettes (not compatible with Shimano Micro Spline or XD/XDR driver bodies). Recommended tyre width: 38–53mm (584 ETRTO). Pairs with the matching WH-RX570-TL-F12-650B front wheel to complete the GRX gravel wheelset.
