    ust valve stem tapered o'rings

    Where do I get just the orings?

    I have tubless rims and I run tubes inside of them. When I blow a tube the air leaks out from the valve stem hole.

    If I can get the the orings for a tubeless stem and slide it over the tube stem I would be all set in the case of a pinch flat.

    The flipside is that I wouldn't know if I had a pinch flat, but I'd like to try this anyway.

    Unless you're running tubeless tires also, you're wasting your time.



    You'll get a pinch flat, and air will leak out from around the bead, through the casing of the tire, everywhere basically. If you're running a tubeless tire with a tube inside it.. well.. uhh.. I guess this will work.

    I run sealant between the tube and tire.

    You're running a UST rim, a tube, and sealant???

    ....buy a UST valve and run full tubeless.

    So, why do you run tubes? Just get proper UST valves, and lose the tubes. Youll drop rotational weight, be able to run lower pressures and get better grip out of your tires. Also, those pesky pinch flats - no longer a worry.

    You tell him Ben....running complete Tubeless...mavic 823's ....My DH bike pedal like 32 pound freeride bike...it's awesome...try it...you will be surprised by how much your bike accelerates faster, the easier it is to pedal and less pinch flats....in addition you can run more pressure in your tires but it still grips as lower pressure with tubes...plus the added pressure - you roll faster with that

    I run Minions and was doing fine tubeless.

    Then I started ripping the tire off the rim and so I added a tube and have had no problems.

    It seems a lot of people at the bike park run tubes in their tubeless rims for the extra security.

    You are all right though. I think I need to play around more with higher pressures.
