Brand-new Vittoria Corsa Elite leaking air around the valve
OK, glued my first tubulars ever and everything went really well.
Out for the first ride and sure got a flat on the rear. Felt like a slow one so I tried to re-inflate but no luck. I could tell that the leak was around the valve stem blowing more or less air depending on how I moved the valve... Replaced it with a spare and got home without problems. Inflated the tire with the compressor and can confirm that the leak is around the valve. As a tubular newbie, I can only think about 2 possible reasons:
Cheers, GS Ps. Valve stem was straight and tire was not moving on the rim... |

I've caused similar leaks on both tubulars and clinchers with a pump chuck that was hard to pull off the valve stem. In the process of pulling the chuck off, the tube was torn at the base of the stem. I think it was caused by twisting when it wouldn't come off, and the twisting caused the leak.

Check out the core. If it's a removable one it could just need to be tightened.

BTW it can be fixed... not like super easy for a newbie but doable, that way you learn how to deal with tubulars... grab a whole valve section from a clincher tube a good to go, or... patch that area where the leak is... figure it out whats the best solution.

Confirmed.
Put in some Orange Seal and saw it oozing out from a little cut with a tiny piece of of shrapnel in it when I inflated the tire. |

Did you pull the shrapnel, and did the Orange Seal take care of the leak??

if the tire is new, I would not a weak valve, you're going to be filling air on a regular basis and you're be just waiting for it to fail. send it to tirealert.com for a new tube.
