  • Detail

    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
