The P ZERO SmarTUBE RS is designed for cyclists who want only the best. Compared to the standard model, it offers up to 1.5 watts more speed thanks to reduced rolling resistance, maximizing every pedal stroke. Available in a wider and complete range of sizes, it ensures a perfect fit for every configuration. Laboratory tests show that a tubeless-ready setup with standard SmarTUBE rolls as fast as one with sealant, but without getting dirty or requiring maintenance. When paired with the P ZERO Race RS tire, both in TLR and Tubetype versions, performance reaches the highest level. Equipped with a Presta valve, the P ZERO SmarTUBE RS is available in different valve lengths to fit every rim profile.
