Shimano GRX RX880 700c Gravel Wheelset

The Shimano GRX WH-RX880 700c Carbon Disc Brake Wheelset is the rolling foundation for your gravel superbike, with a wide and stable tubeless rim and direct engagement 12-speed specific hubs for whatever gearing system you’re into.

Along with GRX 12-speed mechanical components, Shimano is also introducing an updated carbon gravel wheel that’s purpose-built to handle the rough-and-tumble rigors of dirt road riding. The new RX880 wheelset is a full 64 grams lighter per pair than its predecessor and features the same shallow 32 mm rim height for faster acceleration and quicker climbing. The RX880 wheels are tubeless-ready and employ a progressive 25 mm inner rim width that’s suitable for tires from 32 mm to 50 mm wide.

User-friendly compatibility is further enhanced via a revamped DIRECT ENGAGEMENT hub design, borrowed from DURA-ACE wheels, that easily converts between MICRO SPLINE and HG L2 12-speed freehub bodies. It features quick and efficient engagement for rapid acceleration no matter the riding surface. The RX880 hubs and rims are laced with 24 J-bend spokes front and rear that maximize strength and reliability no matter how adventurous your next ride gets.
