Tubeless valves for your road bike.

Stans' new Road Valve Stems are required for tubeless conversion using the old taping method on non-tubeless rims, or can be used as replacement valve for many tubeless rims. Available in 44mm and 55mm lengths to accommodate most road rim depths, except for extremely deep aero wheels. A removable valve core provides easier tire sealant application and hassle-free extender installation. Fits up to an 8mm valve hole. Sold in pairs.

Compatible Tubeless Rims:

  • Stan's NOTUBES ZTR Rims
  • Shimano Tubeless (TL) Wheels
  • Campagnolo and Fulcrum 2-Way Fit
  • Corima Tubeless
  • DT Swiss Tricon Tubeless

Bought these valve stems because my Dura-ace C24's stems did not have removable cores which makes all the difference when applying sealant into the mounted tire that is beaded into the wheel. Stans valve stem was the perfect length and shaped the way it should be to fix into pista air chucks. Thanks, now it's simple to add air or sealant to my Shimano tubeless wheel set.

Good Tubeless Stems

Longer than the OEM stems that came with my Campy 2 Way wheelset and easier to use. Seem to seal up better than the rubber block that comes on most of the other tubeless stems.

Over time the rubber seals at the end of the valve and the rubber seals on the valve cores get torn or become brittle and you need to replace them. Might as well go with the original, Stans. These work great and are a resonable price. In my experience they work on all rims.

I tried cheaper stems and had them pull through the rims. I went back to the original, best tubeless stem. Removable core, seals, what more can you ask for? art deco?

Combined with Stan's fill kit/injector they're fantastic. Tire on, exactly the amount of sealer I want, not a drop on the floor.
