Industry Nine Torch Classic Single Speed Rear MTB Hub
Industry Nine Colors

The Torch Classic Single Speed rear MTB hub features Industry Nine's famous 120 point, 3 degree engagement, 6 pawl mechanism. The industry leading high engagement system is ideal for single speed riders who need lighting quick take-up. Riders will also enjoy the drive system that can withstand 700+ ft-lbs of torque. This single speed hub has a wider hub flange than standard hubs for a nearly zero-dish wheel build.

The Industry Nine drive mechanism is a fairly simple, tried-and-true pawl arrangement. When engaged, each of the three driving pawls itself has three points, providing nine points of contact to the hardened A2, 60 tooth drive ring. The I9 proprietary mechanism allows for a second set of three pawls, phased three degrees from the first. This superior engagement means the hub picks up every 3 degrees of rotation for minimal lag when you are putting power down on the pedals. Quick engagement is ideal for steep climbs where a delay in power can cause you to become unstable or topple over. It also reduces shock into the knees when riding on terrain where you are on and off the power frequently.

The drive system has been tested beyond 700 ft-lbs of torque, which amounts roughly to a super-chipped Ford Power Stroke turbo diesel engine. In over two years of prototyping and testing, I9 had zero drive mechanism failures.
