One of the lightest WTB alloy rims, the KOM Light i23 pairs high-end performance and tubeless dependability. It's sprightly enough for 200 miles of gravel, yet resilient enough for daily trail riding.


  • 23 mm inner rim width is best suited for drop-bar bikes with 32–40 mm tires
  • Open-cavity rim profile eliminates unnecessary weight while also reducing radial stiffness to create a smoother ride
  • Crafted from strong, dependable 6069 aluminum alloy to endure daily hammering on your trail bike
  • 4D angled spoke drilling eliminates binding and lateral loading, and disperses tension more evenly over a greater area
  • 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
