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 aluminum 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.
- High precision CNC machined Aluminum 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
