Simply put, KOM Tough rims were built for bashing. WTB designed them to overcome everything in their unforgiving path. KOM Tough rims are extruded from top-tier 6069 aluminum alloy for unbeatable durability at a reasonable weight, while Dual I-Beam supports further increase strength and lateral stiffness for the world’s most aggressive riders. WTB's unique Solid Strip integration also ensure they'll be the easiest to mount and most reliable tubeless rims you'll ever owned. KOM Tough has been 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.

Main features:

  • Dual I-Beam Support: Two vertical supports within the inner cavity drastically increase the strength and lateral stiffness of our KOM Tough rims. These additional reinforcements counteract spoke loads, which improves stiffness and minimizes deflection in rocky, unpredictable terrain.
  • Dependable 6069 Alloy: Many years of rim development and success have confirmed 6069 to be the perfect aluminum alloy blend for mountain bike rims. Our extensive testing shows other 6000-series alloy to be less ding-resistant, while stiffer 7000-series alloys result in a harsher ride feel and tend to increase pinch flats.
  • 4D Angled Spoke Holes: Drilling spoke holes at an angle eliminates binding and lateral loading of the spoke and nipple interface. It also allows spoke tension to be more evenly dispersed on the nipple rather than loading one side more than the other. Allowing the spoke to depart the rim at a natural angle increases the longterm durability of both the spoke and nipple.
  • TCS Solid Strip: Durable nylon strip that lies between the rim and tubeless tape to prevent tubeless tape from pushing into the spoke holes and ensures a smooth interface between the tire and rim. The smooth surface makes it easier to mount a tire by preventing air from escaping around the bead at each indent during inflation. Solid Strip also protects the airtight system from puncture in the case of a broken spoke.
  • 30 mm Inner Rim Width: Enduro and aggressive trail riders across the globe have adopted 30 mm as the go-to size for tires in the most common widths of 2.4-2.5". Most trail and enduro tires are now designed to be installed on a 30 mm rim and doing so will optimize the air volume, sidewall support and tire profile of those tires.
