WTB KOM Tough I25 29 rim

The WTB KOM Tough rims rims are extruded from high-end alloy to offer maximum durability at a reasonable weight. Its I-Beam construction has evolved to further strengthen the rim with double-supported spokes that offer increased strength and stiffness for the world's most aggressive cyclists.

This rim benefits from TCS 2.0 technology. Built on the proven tubeless-compatible system, it features a more robust, easy-to-install and reliable tubeless system. A recessed channel along the center of TCS 2.0 rims allows installation of the all-new Solid Strip, which prevents the tubeless tape from sagging at the spoke holes and results in a smooth, consistent interface between tire and rim.

The tubeless sealant allows the use of a lightweight tire casing while offering superior puncture protection. TCS tape offers an airtight seal that eliminates the need for an inner tube to retain air in the tire.

The on-ramp bead construction provides a consistent fit between rim and tire for easy installation and inflation. It also allows cyclists to easily move the tire bead to the center of the rim before removing the tire. Designed around ETRTO standards, Beadlock offers the optimum profile and tubeless rim diameter to ensure superior tire fit and retention.

4D angled spoke drilling eliminates lateral stresses and loads, and distributes tension more evenly over a larger area. The spoke bed has been updated to provide a more compatible interface between spoke and rim.
