Wide Rim Tech
25mm rim wide creates a better, more stable support, while the shape of the tire and rim together creates regular, stable air flow, in short, more aerodynamics, less attrition. provides an ideal basis for 25/28mm tires, the sizes currently popular.
2-Way Clincher Tubeless. Tubes or No-Tubes
Use either traditional tires with tubes, or tubeless tires without tubes. Tubeless tires can provide lower rolling resistance and better protection from punctures.
