The Shimano WH-RX870 GRX wheel transforms gravel riding with speed, distance, and pure enjoyment.
Wider rims are essential for maintaining lateral tire stability when running wider tyres at lower air pressures. Shimano's engineering team meticulously analysed the interplay between tyre size, rim width, air pressure, and tyre lateral rigidity to perfect the GRX rim width for 32–50c tyres. The result balances rim weight, strength, and aerodynamic profile to deliver an exceptional gravel wheel that handles demanding terrain with confidence and control.
