The new GRX wheel is perfect for fast, long and fun bike rides on gravel. Wider tires require wider rims to ensure lateral tire stability at low air pressure. Shimano has therefore studied the complex relationship between tire size, rim width, air pressure and tire lateral stiffness to optimize the GRX rim for 32-50c tyres. In addition, Shimano has tried to find the ideal balance between the rim's weight, strength and profile in the search for the perfect gravel wheel.
With the RX880, you'll ride both faster and longer and have more fun while doing it!
