High-end performance doesn't always have to come with a high price tag. The WTB KOM Light rims utilize a 6069 alloy construction with an open cavity design that makes them nearly the same weight as carbon alternatives at a much higher price point. The open cavity design not only reduces weight but produces a more compliant rim that reduces fatigue on long rides, making it perfect for gravel and endurance riders. 


  • AL 6069 alloy construction creates an affordable package at nearly the same weight as carbon
  • Open-cavity rim design reduces overall weight and increases ride compliance 
  • Angle drilled spoke holes reduces stress on the spokes and nipples for a longer lasting platform
  • TCS solid nylon strip sits between the rim and tubeless tape creating a smoother surface and thus easing the tubeless set-up process
  • 21mm internal rim width designed to pair well with road and city tires under 30mm
