Schrader valve cycling tubes
Schrader
— the most popular type of nipple nowadays: used in most entry-level and intermediate bikes, also quite popular in advanced models. It is a cylindrical tube with an external thread, in the centre of which there is a pin — pressing it opens access to the inner volume of a tube. Schrader nipples are also called car nipples, because they are the standard used in car tyres; thanks to this, such tubes can be pumped not only with bicycle, but also with car pumps.Show
