Shimano RX870-700 Disc Tubeless Front Wheel

The Shimano RX870-700 Disc front wheel for tubeless allows for faster, further and more fun gravel rides. Wider tyres need wider rims to maintain the lateral stability of the tyre at low air pressures. Shimano studied the complicated relationship between tyre size, rim width, air pressure and lateral stiffness of the tyre to optimise the GRX rim width for 32-50c tyres. In addition, they sought the best balance between weight, strength and rim profile to deliver an exceptional gravel wheel.
