The Complete Tubeless Setup Kit pairs Silca's Ultimate Tubeless Valves with the Ultimate Tubeless Sealant and a matched injector built to work with it. The valve's removable core gives the injector a clean path straight into the tire, so the carbon-fiber sealant goes in through the valve instead of requiring the bead to come off the rim. Fifty-millimeter valves cover standard and mid-depth rim profiles, and the 500-milliliter sealant bottle carries enough for multiple wheels or a full season of top-ups. What Our Gearhead(R) Experts Are Saying:"I set up a full wheelset with this kit without breaking a single bead. Core out, sealant in through the valve, core back in, done. My hands stayed clean and so did my workbench."
