Set the Standard

The forerunner of our Steel-Series line-up, Trail-S Wheelsets set the standard for quality hoops in their price point. Balancing: weight, strength, reliability and price these do-all wheels will carry through the forest for years to come. While our alloy spoke system wheels still set the standard for performance in all categories we think you'll love the Steel-Series too.

Heart of the Steel-Series

An all-new hub design - Industry Nine’s first straight-pull steel spoke mountain bike hubset. Steel-Series wheelsets employ a 28 hole stacked hub flange maximizing the spoke bracing angle to increase lateral stiffness. Spokes are laced tangentially to the hub flange, which promotes long term durability, since opposing spoke forces cancel each other out, removing most of the spoke stress from the hub flanges. This also allows greater control over bearing press tolerances during the machining phase of hub production, since the hub shell is not under tension.

A2 tool steel

Internally, Torch S-series hubs employ three A2 tool steel pawls and 60 tooth drivering, which are cut with a wire EDM process for exceptional accuracy and strength. This provides a 6 degree/60 point engagement range, allowing for exceptional power transfer and responsiveness in technical terrain. The S-series hubs featured on the Trail S utilize established and proven Torch Mountain system components. Axles, seals, endcap kits, drivering, pawls, and bearing sizes are shared throughout the Industry Nine Mountain, Fatbike and Torch Classic Flanged Mountain hub lineup allowing for easy access to replacement parts.  S-series hubs are also directly compatible with Industry Nine’s existing 6 pawl freehubs (which are available as an upgrade option).


Tying the hub and rims together, it's in important job so we utilize Sapim Race butted spokes and Secure Lock DS nipples for years of problem free use and near universal serviceability.

Complete the Package

Trail S wheels feature an all-new rim profile. Integrating design elements introduced with our premium aluminum spoked Torch Mountain System wheelsets, the new Trail S rim is the perfect balance of weight, width, and features. Making use of 6000 series Performance Alloy, the Trail S complements modern mountain bike tires with dimensions that provide excellent tire support and a competitive weight.
