The WTB KOM Tough rim is built for bashing, whether on a gravity shred sled or fully loaded bikepacking rig. The WTB KOM Tough is extruded from top-tier AL 6069 alloy to provide utmost durability at a reasonable weight.
WTB’s legendary I-Beam construction has evolved to further reinforce the rim with dual support beams that provide increased strength and stiffness for aggressive riders. Proven on the toughest tracks of the Enduro World Series, depended on for daily trail rides, and trusted while bikepacking in remote regions of the world, WTB provides a burly rim for every usage and style of riding.
The 4D angled spoke drilling eliminates binding and lateral loading, and disperses tension more evenly over a greater area. A recessed channel along the center allows the integration of the Solid Strip on WTB’s TCS 2.0 rim and delivers the easiest to mount and most reliable tubeless system WTB has ever made. It prevents the tubeless tape from sagging at the spoke holes and results in a smooth, consistent interface between the tire and rim.
