Built from full carbon and engineered for the demands of gravel riding, the Shimano GRX WH-RX880 front wheel delivers a premium blend of low weight, tubeless-ready versatility and confident handling across mixed terrain. At just 635g, it pairs a stiff carbon rim with cup-and-cone bearing hubs inspired by Shimano's top-tier road lineage — so you get long-service durability and easy field maintenance wherever the road ends.

Highlights

  • Full carbon hooked rim — 32mm deep, 25mm inner width, 30.7mm external width
  • Tubeless ready — pairs with road and gravel tubeless tyres (32–50mm)
  • Lightweight at 635g — carbon construction saves significant rotational mass
  • 24 bladed, double-butted stainless steel spokes in a 2-cross lacing pattern
  • 12mm E-THRU thru-axle hub with 100mm O.L.D. spacing
  • Centre Lock disc brake interface — compatible with Shimano rotor lock rings
  • Cup-and-cone bearings — field-adjustable, long-lasting, low rolling resistance

Carbon Rim & Tyre Versatility

The WH-RX880's 32mm carbon rim sits in the all-round sweet spot — deep enough to offer aerodynamic benefit on paved sections, low-profile enough to remain controllable in crosswinds on exposed gravel routes. The 25mm inner rim width (ETRTO 25-622) accommodates tyres from 32mm up to 50mm wide, letting you run anything from a fast 32mm semi-slick to a voluminous 50mm adventure tyre without swapping wheels.

Hub Engineering

The front hub pairs a 12mm E-THRU thru-axle with Shimano's polished, CBN-finished cup-and-cone bearings. Cup-and-cone construction allows precise preload adjustment in the field using standard cone spanners — a practical advantage on long bikepacking routes away from the workshop. The Centre Lock disc interface accepts Shimano's full range of Centre Lock rotors and requires only a cassette tool for installation or removal.

Spoke Build

Twenty-four bladed, double-butted stainless steel spokes are laced in a 2-cross pattern, balancing lateral stiffness with a degree of compliance that suits rough gravel surfaces. The straight-pull-style bladed profile reduces aerodynamic drag and eliminates the elbow as a stress concentration point compared with J-bend designs.
