Our 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 on our TCS 2.0 rims delivers the easiest to mount and most reliable tubeless system we’ve ever made. FEATURES: TCS 2.0 creates a more robust, easily installed and dependable tubeless system. A recessed channel along the center of TCS 2.0 rims allows installation of the all-new Solid Strip, which prevents tubeless tape from sagging at the spoke holes and results in a smooth, consistent interface between the tire and rim. 4D angled spoke drilling eliminates binding and lateral loading, and disperses tension more evenly over a greater area. Disc-brake only.
