Silca 44mm Tubeless Valve Kit with Speedshield
What is it? A high-strength and low-weight valve stem kit that is designed for tubeless. Included SpeedShields improve aerodynamics while preventing the valve nut from damaging the rim surface.
Who's it for? Cyclists in search of aluminium valve stem kit that perfectly balance lightweight and strength with an engineered solution that improves valve stem sealing, eliminates rim scratches, rattling and improves aerodynamics.
Why We Designed It: SILCA Tubeless valve stems are designed to strike a balance between weight, strength, airflow and ease of installation. We started this project out of our own frustration at the two extremes of product in the market: inexpensive, heavy brass valve stems, or uber-lightweight aluminium stems that had reputations for being problematic in the field. In classic SILCA fashion, we set out to understand the issues and develop a better solution.
Specifications: High precision CNC machined Aluminium Valve Extenders Knurled spherical nuts to eliminate bending load on valve stem Custom molded silicone shield with 3M adhesive backer Less than half the weight of brass valve extenders SpeedShield Improves wheel aerodynamics up to 0.5 Watts at 30mph
