Simply put, WTB KOM Tough rims were built for bashing. An excellent choice for adventure gravel bikes, the WTB KOM Tough i35 rim is dependable for fully loaded touring or bikepacking.


  • 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
  • Designed for 2.6–3.0 in. wide tires; 35 mm inner rim width will provide a rounded tire profile (compared to a flatter tire profile on a 40 mm rim)
  • Dual I-Beam Support: 2 vertical supports within the inner cavity drastically increase the rim's strength and lateral stiffness for aggressive riding
  • These additional reinforcements counteract spoke loads, which improves stiffness and minimizes deflection in rocky, unpredictable terrain
  • 4D angled spoke drilling eliminates binding and lateral loading, and disperses tension more evenly over a greater area
  • Extruded from top-tier 6069 aluminum alloy for unbeatable durability at a reasonable weight
  • Durable nylon TCS Solid Strip lies between the rim and tubeless tape to prevent the tape from pushing into the spoke holes, ensuring a smooth interface between 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
  • TCS (Tubeless Compatible System) is a standardized tubeless system designed by WTB to meet international ETRTO standards
  • TCS components reduce weight, increase traction and virtually eliminate flats for a dependable tubeless system
