WTB KOM Tough

This rim is built for aggressive riding styles, including enduro, trail, and mountain biking. Its high-grade alloy construction and dual support beams make it durable enough for gravity-focused riding, while remaining reliable for long-distance bikepacking.

Yes, it features the TCS 2.0 tubeless system. This design creates a secure, airtight interface with your tires, making it straightforward to set up and maintain a tubeless configuration.

The 4D drilling aligns the spoke holes with the angle of the hub flange. This helps eliminate side-loading on the spoke nipples, which ensures more even tension distribution and prevents the spokes from binding or bending prematurely.

No, the WTB KOM Tough is designed exclusively for disc brake systems. It does not have a machined braking surface on the sidewall.

Asymmetrical drilling helps balance the spoke tension between the drive side and the non-drive side of the wheel. This results in a stronger, stiffer wheel build that is more resistant to lateral flex under heavy loads.

The internal rim width is 25 mm. This width is versatile and works well with a wide range of mountain bike tires, typically ranging from 2.0 to 2.4 inches, depending on your preferred tire profile and traction needs.
