Our flagship CZR carbon rims deliver minimal rotational weight and fine-tuned compliance to make you feel at one with the terrain. Reinforced spoke holes, TCS 2.0 technology, an asymmetrical design and two years of development make them the most dependable carbon rims on the market. CZR rims set themselves apart from the pack by providing unbeatable strength and ride quality at a more affordable price. Available in i23 and i30 inner widths to satisfy the needs of both gravel and mountain riders.Features: - Reinforced spoke beds, proven 4D angled spoke hole drilling and an asymmetrical design…all the necessary ingredients of an incredibly durable rim.- 30 mm inner rim width (mountain-focused).- When compared to the competition, lab tests proved our CZR carbon rims to be lighter overall, more impact resistant, and laterally stiffer while remaining vertically compliant. To be precise, our CZR i23 rims were 38% more impact resistant than their direct competition while our CZR i30 rims were 10% more impact resistant.TCS 2.0:- TCS 2.0 introduces 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. 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.Disc Only:- Disc Only rims benefit from lighter weights because they do not require the amount of material traditional rims require for the braking surface. Do not use Disc Only rims with rim brake systems, such as cantilever or v-brake.4D drilling:- The spoke holes are drilled at precise departure angle to align the spoke head and nipple with the hub flange, eliminating binding and lateral loading while also dispersing the load more evenly over a greater area. This prolongs the wheel's lifespan and increases stability. I-Beam: - The I-Beam adds strength to the inner rim cavity. This distinctive support counteracts spoke loads and provides lateral rigidity.Specifications:- Wheel size: 29´´- Inner width: 30 mm- Weight: 472 g- Spokes holes/Offset: 28 / 5 mm- Tubeless tape width: 35 mm- Rim size Designation: 30-622
