Continental Presta 700c Light Tube
20 grams lighter than Continental's standard tube. Good low-cost way to reduce rotating weight. Slightly less puncture resistant than standard weight tube. Offered in three valve stem lengths. Standard rims use a 36mm, semi aero rims like the Mavic Ksyrium use the 48mm, and deep aero rims use the 60mm valve stem. Select the size you require.
