When you need to go fast again: The 23 gram lightweight and extremely compact S-Tubo-Road-700C stands out with its extremely low rolling resistance, which puts butyl tubes in the shade and is as low as that of latex tubes. With a 78 % smaller pack size and the same robustness as standard inner tubes, the S-Tubo-Road-700C is the ideal choice as a spare tube and when competing for the best times. Suitable for all road bikes with disc brakes. Available with black or orange valve.
