2Bliss Ready Valve Stem - any good?
Just taken delivery of my new Stumpjumper Hardtail; job one is to get some winter tires on. I chose Specialise Purgatory for the front, and Ground Control at the back, both 2Bliss Ready. The Roval wheels have 2Bliss Ready rim tape inside, and Specialized 2Bliss Ready Valve Stems came with the bike, and the dealer told me I was ready to go tubeless. With everything "Specialized" and recommended to work together, it should be easy.
Trouble is, I can't get the valve stems to seal. I have only use DT Swiss and Scott tubless conversions in the past, and had no trouble over many years BUT - are these specialized valve stems any good? Or is there some magic trick I have missed? I have checked the instructions in http://www.specialized.com/media/wha...G0290_revA.pdf and verified the valve stems are correctly orierntated. But they slowly leak air: tire inflates and sseems to seal OK but overnight it is soft and under water I can see air bubbling slowly from around the valve stem. I am using Stans btw
Anyone else have good or bad experience with these parts?.
