Built for bashing whether on a gravity shred sled or fully loaded bikepacking rig. KOM Tough rims provide a burly rim for every usage and style of riding, from the toughest tracks of the Enduro World Series to daily trail rides and bikepacking in remote regions of the world. WTB's I-Beam construction has evolved to further reinforce the rim with dual support beams that provide increased strength and stiffness for the world's most aggressive riders.
