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.
