CH 45 PRO GX

Go wider. Go faster.

The CH 45 PRO GX is your gravel racing upgrade for technical, varied terrain, fast sprints, and maximum control with high-volume tires. Designed for races where agility, traction, and precise handling make all the difference—when the terrain gets tougher, the racing line is constantly changing, and every burst of speed counts.

With its extra-wide 30 mm hookless rim width, the CH 45 PRO GX provides an optimized fit for modern gravel tires and ensures high stability even with large tire volumes. The wide rim shoulder reliably supports the tire during fast turns and allows for lower tire pressures, providing more traction and control on rough terrain. The deliberately chosen rim height of 45 mm keeps the wheel both lightweight and aerodynamically stable. Agility, controlled handling, and a direct riding feel in technical racing situations are the result of a design consistently tailored to modern gravel racing with wide tires.

From a technical standpoint, the CH 45 PRO GX features a D2R Aero carbon rim with a 30 mm hookless rim depth and a 36 mm outer width—optimized for modern, high-volume gravel tires. 18 SAPIM CX carbon spokes per wheel minimize rotating mass, provide damping on rough sections, and maximize power transfer. Combined with the Leeze PRO hub, the result is an uncompromising gravel race wheelset with a total weight of just 1,240 grams.
