What is it?
The highest quality Tubeless Valve stems with SpeedShield Rim Protectors for reduced weight, improved aerodynamics and more robust tubeless conversions, especially with carbon and deep section wheels.
Who's it for?
The uncompromising cyclist running a tubeless set-up on rims less than 30mm to 65mm deep.Why We Designed It | Product Specs | Getting Started
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.
Perhaps the most exciting feature of the SILCA tubeless program is the Speed Shield. Speed Shield grew out of our frustration with valve stem nuts scratching our rims...particularly our carbon rims! The concept developed through an initial study we did on ways of improving aerodynamics around the valve stem, which proved out that 'shielding' the valve stem could save about 0.15-0.20 watts of energy per 10mm of valve stem encased in the shield.
Please consult with your wheel or rim manufacturer before converting any product that is not already deemed Tubeless compatible for further instruction.
