\n\t\tThe Shimano GRX WH-RX870 Carbon Disc Wheel is a gravel tuned 700c tubeless wheelset offering all the technology of Shimano wheels balancing the best combination of rim weight and strength to deliver an exceptional gravel wheelset.
\n\t\t
\n\t\tThe new GRX wheel supports gravel rides that are faster, further, and more fun. Wider tires need wider rims to maintain lateral tire stability at low air pressures. Shimano studied the complicated relationship between tire size, rim width, air pressure, and tire lateral rigidity to optimize the GRX rim width for 32-50c tires. In addition, we pursued the best balance of rim weight, strength, and profile in order to deliver an exceptional gravel wheel.
