WTB KOM Light i21 Rim

Features

• 21 mm inner rim width is best suited for road and commuter bikes with narrow tires of 30 mm or less
• 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
