Coming equipped with tubeless ready technology, you’ll benefit from tubeless advantages such as the ability to run lower tyre pressures for increased traction on rough terrains, lower rolling resistance and fewer risks of flats or punctures as you battle for the finish line. With improved traction over bumps with reduced negative feedback, this model truly maximises performance and comfort.Vibrocore DampingSpank has injected this MTB rear wheel with an award-winning built-in damping system called Vibrocore. Its proprietary, biodegradable, complex foam core is designed to reduce vibrations from the ground, while also increased the fatigue life of the rim.
