Hi,

Im trying tubeless out and thought it was going alright however i have a leak around the valve. Do the notubes valve stems work by tightening the small nut on the outside of the rim to gain a seal? Or is there something else i need to do?
The tighter i do the nut the less air comes out however i cant do it tight enough so that no air comes out! Im using mavic crossmax rims, with stans sealent.

Thanks

The eclipse system has a rubber washer between the rim and the locknut to seal it. Failing that try some silicone sealant.

Are you using a Rim tape or the rim strip ?

Thanks Sandwhich, I will see if i can find something to do that.

Offroading, niether because they are UST rims which only have the spokes going through 1 rim wall so there is an air tight surface to mount the rim onto.

OK. Are they leaking alot or just a bit ?

Have you tried letting the sealent pool in the tyre below the valve then shaking the tyre back and forth so the sealant slashes around - it should seal the gap over the valve stem.

I gather your are using the proper Valve too as there are different ones...
