The tyre can run with lower pressures providing better grip without risking snakebites. The lower pressure also results in a more comfortable ride. Eliminating the tube means there is no friction between tube and tyre and therefore less rolling resistance when the tyre rolls over the ground and obstacles. If tubeless milk is used, the tyre can self-seal stings and small cuts. A big advantage for all those who like to ride for long and far away from the nearest bike shop.Buy DT Swiss Wheels & Tyres from Chain Reaction Cycles, the World’s Largest Online Bike Store.
