Center lock disc brake wheel Shimano grx wh-rx870-tl-f12-700c

Product Description

The new GRX wheel helps you ride routes at Gravel that are faster, go farther and bring you more fun. Wider tires require wider rims to maintain their lateral stability at low pressures. Shimano studied the complicated relationship between tire size, rim width, air pressure and tire lateral stiffness to optimize the GRX rim width for tires from 32 to 50 mm in section. In addition, we looked for the best balance between weight, strength and rim profile to provide an outstanding wheel for the Gravel. - ・First carbon wheel SHIMANO GRX - ・100% carbon rim with 32mm height - ・Inner rim width: 25mm - ・Recommended tire size: 32-622 - 50-622 - ・Compatible with 11 & 12 speed road transmissions
