Industry Nine 1/1 Mountain Classic hub set Boost CL
Industry Nine's 1/1 Mountain Classic hub set combines precise CNC manufacturing, lightning-fast power transmission and typical US craftsmanship to create a robust, lightweight base for high-quality MTB wheels in the Boost standard with Centerlock disc brake mount.
Maximum performance for trail and enduro
The 1/1 Mountain Classic Boost Centerlock hubset is designed for demanding trail and enduro riders seeking reliability and direct power transfer. The rear hub utilizes a dual-phase, offset-action pawl freehub with 90 engagement points and approximately 4 degrees of engagement angle, providing very direct acceleration and finely adjustable traction.
Robust construction, precise manufacturing
The hubs are precision-machined from high-quality aluminum and offer a stable Boost spacing of 15x110 mm at the front and 12x148 mm at the rear, compatible with modern MTB frames and forks. Depending on the version, 28 or 32 hole patterns are available, allowing for both lighter and particularly robust wheel builds.
Centerlock disc brake mount and modern freewheel options
The Centerlock mount allows for quick and secure installation of the brake discs and ensures a clean, torsionally rigid connection. Common freehub body standards such as Shimano Micro Spline, Shimano HG, or SRAM XD are offered for the rear hub (depending on the model), so the hub set can be combined with current 11- and 12-speed drivetrains.
Emotion: direct response and rich sound
The quick engagement of the 1/1 freewheel provides the feeling with every pedal stroke that no power is wasted, resulting in a very direct, sporty riding feel both uphill and downhill. The characteristic, yet not excessive, freewheel sound underscores the high-quality nature of the hubs and provides acoustic feedback of the working mechanism on the trail.

Here's what we think about it
Many riders praise the very direct acceleration of the 1/1 Mountain Classic hubs, which is particularly noticeable on technical climbs and when accelerating out of corners.
One user reports that the hub set has been running completely smoothly for several intensive enduro seasons and shows neither play nor dropouts in the freewheel despite hard use.
It is also frequently emphasized that the hubs offer excellent value for money within the high-end segment and represent an attractive alternative to significantly more expensive boutique hubs.
Another rider describes how her bicycle feels "noticeably more lively" with the 1/1 hubs and that she especially appreciates the combination of stable running and a defined, but not too loud, freewheel noise.
Overall, smooth running, build quality and the characteristic sound of the freewheel are cited as emotional highlights that provide additional riding pleasure on the trail.
