This gravel-ready rim features an asymmetrical carbon build that allows it to deliver minimal rotational weight and fine-tuned compliance to make you feel at one with the terrain. WTB has also put this model through a series of lab tests and found that its CZR rim is lighter overall, more impact resistant, and laterally stiffer while remaining vertically compliant. After two years of development, this durable rim offers excellent reliability, wherever your next gravel bike adventure leads you. Gravel Bike Rim with Tubeless TCS 2.0 Technology WTB has equipped this gravel bike rim with its renowned TCS 2.0 technology, which provides a more robust, easily installed, and dependable tubeless system. A recessed channel along its centre allows for the installation of the updated Solid Strip, which prevents tubeless tape from sagging at the spoke holes and results in a smooth, consistent interface between the tyre and rim. Installation of the stout Solid Strip allows for more pliable, and easy to install, TCS Tape to provide the airtight seal needed for a tubeless system. This means that riders will enjoy tubeless benefits such as the ability to run lower air pressure for greater stability on rough terrain, increased comfort and less chances of punctures or flats.
