WTB KOM Tough Rim

This rim is built for aggressive trail riding, enduro, and all-mountain use. It is engineered to handle high-impact forces and demanding terrain where durability is the priority over absolute minimum weight.

The 30mm internal width is a versatile sweet spot for modern mountain biking. It works best with tires ranging from 2.3" to 2.6" wide, providing a stable, square profile that helps prevent tire squirm when cornering hard.

While it is technically possible, the KOM Tough is likely overkill for pure cross-country racing. It is heavier than dedicated XC rims because it uses extra material to increase impact resistance, so you might prefer WTB's lighter KOM Light series if weight savings are your primary goal.

Yes, WTB designs their rims with a bead-lock system that makes setting up tubeless tires straightforward and secure. You will just need to add tubeless tape, a valve, and sealant to complete the setup.

The 'Tough' designation indicates a thicker rim wall construction designed specifically to resist dents and damage from rocks and harsh landings. The KOM Light is designed to save weight, whereas the Tough version prioritizes structural integrity for aggressive riders.
