Shimano GRX RX870 Rear Wheel 28" SH 12S CL CB Ø12mm - Black

The new GRX wheel supports gravel rides that are faster, further and more fun.
Wider tires require wider rims to maintain lateral tire stability at low air pressures.
Shimano has studied the intricate relationship between tire size, rim width, air pressure and lateral stiffness to optimize the GRX rim width for 32-50c tires.
In addition, Shimano strived for the best balance between rim weight, strength and profile to deliver an exceptional gravel wheel.
