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 aluminum 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 | Product Specs | Getting Started

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 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
  • Limited Warranty

Getting Started:

The SILCA Tubeless Valve Kit with SpeedShield is ready to use when removed from the package. If you would like to learn more about features, functions and maintenance of the Tubeless Valve Kit with SpeedShield, please visit the SILCA resource center.

Great product!

Can't find these in the UK anywhere. Was so happy to see these arrive in the post from the US. Love the aero shields, look so much nicer than standard valve kits.

Happy with it

Exactly as advertised and delivered quickly. Thumbs up for the product and Silca's service

Weapons grade upgrade

Having seen these used on standard rims was curious to see if a speed wobble could be cured on my ENVE 7.8 tubeless rims. When the valves arrived they were of great quality as would be expected and when placed on the scales half the weight of the standard ENVE valves. Fit was easy with attention to detail as required with any tubeless instillation as this is key spot for air bleed. The result.... I pleased to report no more speed wobble, they look great combined with the balance kit and all you hear now is the sonic boom as these get up to speed. Small difference can make a huge difference an these are just them. The challenge to try and get more for my Mavic winter rims but these are like rocking horse poo at the moment and everywhere reporting out of stock NOoooo
