WTB Proterra Front Wheel

The Proterra Tough front wheel is designed for 15mm thru-axle forks and uses a 6-bolt disc brake interface. Please verify your fork's axle spacing and brake rotor mount type before purchasing.

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

Yes, the Proterra Tough is tubeless-ready out of the box. It comes with the necessary rim tape installed, so you only need to add your preferred tubeless valves and sealant to complete the setup.

6069 aluminum is a higher-grade alloy that offers a superior strength-to-weight ratio compared to the more common 6061 aluminum. This allows the rim to be both lighter and significantly more resistant to dents and impacts on technical terrain.

Yes, the wheel utilizes standard sealed cartridge bearings, which are designed to be easily serviced or replaced by a home mechanic with basic tools. The double-sealed design also helps extend the time between maintenance intervals by keeping dirt and moisture out.

The 'Tough' designation and I-Beam construction are specifically engineered for aggressive trail and enduro riding. It is built to handle the heavy impacts and high speeds associated with technical, demanding mountain bike trails.
