WTB&';s proprietary 4D spoke drilling prevents binding and lateral loading of the spokes, while the spoke bed itself has been updated to provide a more compatible interface between the spoke and rim. Integration of the all-new Solid Strip the TCS 2.0 rims delivers an easy to mount and reliable tubeless system. TCS2.0 rims require the application of TCS tape on top of the Solid-Strip Patented CVX technology strengthens the spoke bed without increasing weight, by thickening material where it s needed and removing where it s not. The unique geometry also increases contact area between the nipple head and rim to better distribute load and reduce stress at the spoke hole TCS 2.0 creates a more robust, easily installed and dependable tubeless system 4D angled spoke drilling eliminates binding and lateral loading, and disperses tension more evenly over a greater area Item Specifications Brake Compatibility Disc Only Brake Track None Color Black Defined Color Black Eyelets None Hub Drilling 32 ISO Diameter 686 / 32" Manufacturer Spec ERD (mm) 667 Material Alloy Rim Center Offset (mm) 0 Rim Material Alloy Rim Width (Internal) 30 Tire Type Tubeless Ready Valve Presta Weight 519 Wheel Size 32" WTB KOM Light Rim Rims
