In Stock
The Shimano GRX WH-RX880 is a full carbon gravel rear wheel built for riders who demand lightweight performance across mixed terrain. A 32mm rim profile keeps the wheel nimble on climbs and composed in crosswinds, while the wide 25mm internal width opens up tyre choices from 32mm right through to 50mm — ready to roll on road, gravel, or dirt.
Highlights
- Full carbon 32mm rim — fast-accelerating, low-profile design
- 25mm internal rim width for tyres 32–50mm
- DIRECT ENGAGEMENT freehub technology from Dura-Ace for instant power transfer
- Micro Spline freehub body — 12-speed Shimano MTB cassette compatible
- Tubeless-ready construction (rim tape required)
- Centre Lock disc brake interface (140mm rotor minimum)
- 24 J-bend bladed stainless steel spokes, butted for weight savings
- 12x142mm E-THRU thru-axle standard
- Sealed cup-and-cone bearings with contact seals on hub and freehub
Carbon Rim Construction
The WH-RX880 rim is moulded from carbon fibre for an optimal balance of stiffness and ride quality. At 32mm deep and 30.7mm wide externally, it cuts through air efficiently without becoming unmanageable in variable conditions. The 25mm internal width pairs ideally with modern wide-section gravel tyres, providing a stable tyre profile and improved rolling efficiency. Rim tape is required for a tubeless setup.
DIRECT ENGAGEMENT Hub Technology
Shimano's DIRECT ENGAGEMENT ratchet mechanism — developed for the flagship Dura-Ace wheelset — filters down to the GRX line in the WH-RX880. The system reduces rotational play in the freehub body, translating pedal input into forward motion with greater immediacy. Contact seals protect the hub internals and freehub bearings from mud, grit, and moisture across gravel and off-road riding.
Compatibility & Fit
This Micro Spline variant is designed specifically for 12-speed Shimano mountain-bike cassettes (9-45T, 10-45T, 10-51T). It is not compatible with HG 10-speed or 11-speed cassettes, nor with HG L2 road cassettes — ensure your drivetrain matches before ordering. Fits frames with a 12x142mm rear thru-axle. Disc brake only; not compatible with rim brake frames. Centre Lock rotor interface requires a compatible lockring tool and rotor (sold separately).
