Silca Ultimate Tubeless Valve Stem Set - Black - 70mm

The SILCA Ultimate Tubeless Valve Stem Set in 70mm is built for deep-section rims where standard valves simply don't reach. CNC-machined from aluminum with a removable valve core, these stems make sealant injection straightforward and eliminate the frustrating guesswork of seating a valve from the outside of a tall rim. A 4mm hex socket at the base of the valve locks it in place while you tighten the external nut. Designed as part of the SILCA Ultimate Tubeless system — pair with Ultimate Tubeless Tape and Ultimate Tubeless Sealant for a complete, high-performance setup. CNC-machined aluminum valve stems Removable valve core for easy sealant injection 4mm hex socket for secure rim installation 70mm valve length — designed for deep-section and aero rims Compatible with SILCA Ultimate Tubeless Tape and Sealant Sold as a set (2 valves)
