The BASIC bicycle tubes we retail are the ones we source and use for our customers' tubes replacement. They are of fair quality for their price.
Usually, there are 2 types of valves - Schrader / American Valve (AV) & Presta / French Valve (FV) and they come in sizes from 33mm - 48mm for BASIC tubes.
VITTORIA tubes are made of tough, puncture resistant butyl.
