The Industry Nine 1/1 GRCX-S wheelset is a hand-built aluminum wheelset for gravel, cyclocross, and demanding rides off paved roads. The wide rim and robust build with 28 Sapim Race spokes per wheel are designed for high load capacity and reliable performance.
The Industry Nine 1/1 hubs are manufactured entirely in-house. In the rear wheel, six pawls engage with a 45-tooth drive ring in two groups, enabling a 4-degree engagement angle. Larger bearings and redesigned pawl pockets support power transmission under high loads.
The wheelset is suitable for riders who use wider gravel tires from 35 mm and prefer a stable, easy-to-maintain build. External nipples, classic J-bend spokes, and pre-installed rim tape and valves simplify servicing and tubeless setup.
Highlights:
- Industry Nine 1/1 hubs: manufactured entirely in-house and equipped with a redesigned pawl and bearing system
- 4-degree engagement angle: six pawls engage with a 45-tooth drive ring in two groups
- Wide aluminum rim: designed for gravel tires from approximately 35 mm and tubeless use
