Cross Country and Cross Mountain UST Tubeless rim. Tire and wheel design that offers better performance by eliminating the use of rim tape and tube. This benefits the rider by optimizing grip and efficiency by regulating the tire pressure according to the type of terrain, with less risk of flats even at low tire pressure
Greater efficiency due to absence of heat and friction between tube/rim tape/tire. No flat tires due to pinched tubes, torn valve stems or rim tape problems. Very slow deflation rate if punctured. Also employs FORE technology that consists of "piercing" only one rim wall with no loss of material and then tapping the resultant alloy tunnel. This is beneficial because there are no holes in the rims upper bridge which yields strength and stiffness. Also there is less weight with fewer spokes, no eyelets or rim tape. k
