◂ Rims ▸
Gravel carbon wheels require a balance of strength and adaptability. ProX gravel wheelsets are built with a 26 mm internal rim width, optimized for 700×35C–50C gravel tires. With depth options of 40 / 45 / 50 mm, this range delivers a well-rounded solution for varied terrain and riding styles.
Rim Depth Comparison: 40mm vs. 45mm vs. 50mm
Selecting the right rim depth depends on how and where you ride:
40mm – Best suited for technical and unpredictable terrain. The lower profile improves handling, reduces weight, and offers greater stability in crosswinds—ideal for steep climbs and tight, demanding trails.
45mm – A balanced all-round option. It provides improved aerodynamic performance over shallower rims while maintaining moderate weight, making it a great choice for mixed gravel and paved sections.
50mm – Designed for speed on smoother gravel and rolling courses. The deeper profile enhances aerodynamic efficiency and helps maintain momentum, with a slight trade-off in weight.
◂ Hubs ▸
- Straight pull spoke system and 24 spoke holes for both front and rear wheel.
- Front Hub 12/100mm TA & Rear Hub 12/142mm TA.

◂ Spokes ▸
The popular Pillar PSR AERO 1423 spokes are used.
The spokes are manufactured using Pillar's patented cold forging technology, increasing strength by up to 20%.
Featuring an aerodynamic streamlined design, they offer excellent elasticity and a low drag coefficient.
