New Shimano GRX Carbon Wheel supports gravel rides that are faster, further, and more fun. Wider tyres need wider rims to maintain lateral tyre stability at low air pressures. Shimano studied the complicated relationship between tyre size, rim width, air pressure, and tyre lateral rigidity to optimize the GRX rim width for 32-50c tyres. In addition, they pursued the best balance of rim weight, strength, and profile to deliver an exceptional gravel wheel.

The Centre Lock system makes an easy rotor installation possible with spline mount and a lock ring. The lock ring mounting system reduces the total working hours by shortening the amount of time of both installation and de-installation. In addition, the secure fixing by the spline mount enhances precision and rigidity while improving braking efficiency.

The tool-less type thru-axle skewer system optimizes rigidity and weight balance and enables easy operation with a reliable internal cam mechanism. The 15mm thru-axle system is 15% stiffer torsionally and 25% stiffer in transverse shear than a traditional 9mm quick release front axle system. High rigidity is secured while keeping the optimum weight balance. The E-THRU axle hub system minimizes the distortion of suspension while maintaining lightweight for riding around sharp corners at high speed. An 8mm thru-axle system for the trekking/hybrid hub and dynamo hub and a 12mm thru-axle system for the rear are also available.
