WTB Proterra Gravel Wheel

The 25mm internal width is optimized for modern, high-volume gravel tires. It provides a stable base for tires ranging from 35mm up to 50mm, allowing you to run lower pressures for better traction without the tire feeling squirmy in corners.

Yes, these wheels are designed for a 12mm thru-axle standard, which is the current industry norm for most modern gravel bikes.

The 6-pawl hub offers 5-degree engagement, which means there is very little lag between when you start pedaling and when the power hits the rear wheel. This responsiveness is particularly helpful when you are navigating technical, punchy climbs or need quick acceleration.

Yes, they feature WTB’s TCS (Tubeless Compatible System) design. You will just need to add your preferred tubeless tape, sealant, and valves to complete the setup.

No, these hubs are specifically designed for Center-Lock disc rotors. If you currently use 6-bolt rotors, you will need to purchase Center-Lock adapters to make them compatible.

The open-cavity profile is a strategic design choice that removes unnecessary material to reduce weight without sacrificing strength. It creates a rim that is light enough for long days in the saddle but robust enough to handle rough, unpaved terrain.
