What is the difference between a Presta and Schrader valve?
Bicycle tubes come with two different valve styles; Schrader or standard “car-type” valves and Presta or French valves. The Presta valve is the more slender of the two and is slightly more cumbersome to use, having a lock nut instead of a spring to ensure closure. However, these two features have kept the Presta valve in use on high end bicycles and tubes running higher pressures (road bikes). SLiME is installed through the valve stem. In order to do so the core of the valve must first be removed. Generally, Presta valves are a one-piece set up without a removable core, which makes installation of SLiME difficult at best. We offer pre-treated tubes with presta valves. Our tubes have a two-piece Presta valve set up which enables us to pre-treat them with SLiME. Click here for images.
