WTB Proterra Tough Wheel

As the name suggests, this wheelset is built for aggressive trail riding and demanding terrain. The 6069 aluminum construction is reinforced to handle the impacts and stresses of technical mountain biking while keeping the weight manageable for longer rides.

The 30mm internal width is optimized for modern trail tires, typically ranging from 2.3 to 2.6 inches wide. This width provides excellent sidewall support, which allows you to run lower tire pressures without the tire squirming or folding in corners.

Yes, the Proterra Tough I30 features WTB's TCS (Tubeless Compatible System) design. It is fully tubeless-ready right out of the box, making it straightforward to set up with your preferred sealant and valves.

The rear hub features a 6-pawl design with 5-degree engagement. This provides a very responsive feel, meaning there is minimal lag when you put power into the pedals—a significant advantage when navigating technical, rocky climbs or needing quick acceleration.

These wheels use standard modern mountain bike spacing: a 15x110mm thru-axle for the front and a 12x148mm (Boost) thru-axle for the rear. Please verify that your frame and fork match these dimensions before purchasing.

The hubs are designed for 6-bolt disc brake rotors. If you are currently using Centerlock rotors, you will need to switch to 6-bolt rotors or use a Centerlock-to-6-bolt adapter.
