PROGRESS FRONT WHEEL GRX40 PGRUGRX40CDUNBZ

The perfect blend of gravel and all-road performance with our most sophisticated technology for maximum performance at an ultralight weight. A new, wider rim with a 28mm internal width means no tire width limit. This winning combination comes with the NEW NITRO2 ceramic hub.
Advanced Aerodynamics:
Maximum aerodynamic efficiency for exceptional performance with seamless tire integration. Wide, curved rim minimizes air resistance, even with very wide tires. AIR+PLUS design for maximum bike control in crosswinds and gusts. Harness the wind for a significant aerodynamic advantage.
High-Tech Construction:
The material of the future: T1000 Carbon Fiber with Graphene Epoxy, the lightest discovered to date. Nitro2 ceramic hub with minimal friction and maximum durability. Hand-trued with SAPIM Aero CX-RAY spokes and self-locking nipples with correct tension on each spoke.
Nitro2 Ceramic Disc Hub:
Ultra-lightweight, machined from 7075 aluminum with PAL-TECH 100% parallel, high-precision coaxial ceramic bearings with a larger 28mm diameter to withstand thousands of kilometers. The Nitro2 offers a unique balance of weight and durability.
With the optimized 2:1 spoke lacing, we equalize the tension of the left and right spokes. The larger diameter on the right wing gives us a +2º increase in spoke angle for greater lateral stiffness.
"Wheels with more balanced spoke tension, more rigid and more durable."
