Orange Seal's RVC Valve Stems make setting up tubeless tires easier.
With an oversized, trim-able base, these valve stems provide a nice seal for tubeless setups. Their unique design also helps prevent them from pulling through the rim, and each size features a removable valve core.
The RVC Valve Stem is sold in packs of two and comes with a lock nut and cap. Available sizes: 48mm, 60mm, and 80mm.
