Stiffness, all-terrain proficiency, and ready to be custom tailored - GRCX TRA has you covered. At the heart of the GRCX TRA is our direct-thread one piece alloy spoke, fully customizable Torch Road Alloy system chassis ensures accurate handling and a bevy of thru-axle and FH body options. Completing the package is our GRCX rim, an alloy hoop sporting a 24.5mm inner width, tubeless optimized design and a profile more at home on singletrack than the peloton. On-rails handling, off-road confidence, and arresting looks - GRCX delivers in spades.
The Torch Road Alloy performs in a space where a tarmac-focused wheelset might be overmatched, but a mountain wheelset would be overkill. Ideal scenarios for the TRA line-up would be in the CX start grid, fast moving, light-duty off-road explorations, or hammering out long days on Forest Service roads. The TRA chassis represents a confluence of the best characteristics from the Torch Mountain system wheelsets and the Torch Road disc platform - sturdy meets svelte. An all-new hubshell forms the foundation of the TRA chassis, allowing direct threading of the spokes to the hub; a long-standing and defining performance and durability element of Industry Nine mountain bike wheelsets. Compatible with all thru-axles and road drivetrains, the Center Lock specific hub is built off Industry Nine's established Torch Road Disc internals, so service and support parts are already present and available in the field.
Machined and anodized totally in-house, the Torch Road Alloy hubs accept 24 spokes laid out in a clever yet familiar 2:1 lacing pattern. By using a differential spoke count, TRA wheelsets are able to cut weight, and balance spoke tension, yet retain power-amplifying stiffness.
Securing the rim to the hub are Industry Nine's straight-pull aluminum spokes. The one-piece design integrates standard 14g wrench flats located outside of the rim to keep service intuitive, but eliminates the undersized traditional spoke nipple in favor of a more robust connection between hub and spoke. Directly tapping into the hubs courtesy of large, rolled threads the 2.9mm diameter spokes taper to 2.7mm as they exit the hub and approach the rim.
