Where endurance meets performance, GR45 Pro is born for gravel combining lightweight performance with all-terrain durability. The balanced profile, rim width and gravel-optimized hubs ensure explosive power transfer on any surface and transform rough roads into smooth sailing.

Integral Design, Rides Light and Fast

GR45 Pro applies HI-MOD carbon fiber on rim. While the rim, spoke and hub remain stiff, we optimized materials and structure to keep it as light as possible. The light design effectively reduces driving weight and improves sprinting performance.

*The wheelset weight doesn’t include the weight of the quick-release skewer and rim tape. A tolerance of ±3% applies to the weight, and the actual wheelset weight should prevail.

45mm Aero Profile, Balanced Rigidity for All-terrain Domination

Compared with lower-profile wheels, the 45mm rim depth reduces frontal wind resistance, delivering significant aero gains. At the same time, it achieves the perfect balance of torsional and lateral stiffness, ensuring uncompromising power transfer under high-torque efforts.

Where aerodynamics meets unwavering rigidity, the GR45 Pro unlocks peak performance across every terrain.

32mm Fat Rim, Ultimate Comfort

Engineered for gravel bikes, the 32mm external / 25mm internal width wide rim delivers superior aerodynamics in turbulent crosswinds while enhancing stability.

When paired with 35c and above wide tires, the wider rim provides enhanced tire support, reducing deformation to improve cornering grip and steering precision. Meanwhile, it enables lower tire pressure, significantly boosting comfort on rough terrain by absorbing vibrations more effectively. This scientifically optimized combination achieves the perfect balance between tire stability, handling control, ride comfort, and aerodynamic efficiency.

Tubeless-Ready, Tape-Free

Compatible with both tubeless and clincher tires. Without spoke holes, the rim is tubeless-ready with no need of rim tape.

Elaborate Hub Design, Engineered for Gravel

Front Hub: Features a 24-hole, 1:1 lacing pattern with crossed spokes on both sides for enhanced durability. This design engages more spokes under braking for enhanced stability and power distribution. It effectively disperses impact forces on rough terrain and delivers smoother braking performance.

Optimized Flange Spacing: The front hub’s wider flange spacing improves spoke bracing angles and tension distribution, maximizing lateral stiffness and support.

Rear Hub: Utilizes a 24-hole, 2:1 lacing configuration to reinforce drive-side efficiency while maintaining critical lateral rigidity.

More Powerful Design

36-tooth flat ratchet offers greater engagement force, durability, and stability, with smoother, consistent sound. It supports quick swaps for different tooth counts, adding versatility.

GR45 Pro features Pillar Wing20 steel spokes. Compared with carbon spokes, steel spokers have superior vibration absorption, impact resistance, and durability while on rugged gravel terrain.

GR45 Pro wheelset is UCI approved, meeting the strict performance and safety standards of professional racing—so you get lab-tested reliability that thrives in real-world gravel chaos.
