word of warning on preasure check valve caps - ghostbiker - 23-09-12
Just thought i would post a word of warning to anyone useing the preasure valve caps that turn green /red if the psi drops
i have used the for a couple of years without an issue but i was on a track day this week and as i was going in to westfield bend at brands the valve stem on my tyre sheared off and dumped all my air.
affter a trip to the gravel trap ( scrubbed most of the speed off before i went in and stayed upright through luck not skill) and a new pair of pants it was clear the valve stem had cracked from the added weight of the valve cap.
I was lucky they had a tyre place in the pits who fitted a new stem and i was back out on track next session but he made it clear he also thought the cap was the cause.
as i say i have used them for a couple of years and not had a problem but i will not use them again thats for sure.

Did your valve blow out? i thought those (green/ red pressure things where just caps) or is it a valve & cap product. My valve came out on the work bench the other week it had corroded (obviously the valve didnt get changed when the tyre was done)

its a normal valve stem, the cap itself is the problem as its extra weight. this caused stress on the valve stem and broke it about half way up.

This happened to me too, went for solid angled valves in the end and have now took them off all together. Another pointless gimmick from China I have but wont be using. :b
