Afternoon all.
I have always carried a couple of threaded Co2 cylinders, an adaptor and a spare tube. I`ve always used short presta valve tubes, the ones with the threaded washer to fix them to the rim. On the couple of occasions I`ve had to use the cartridges there`s never been a problem.
When I was in Halfords buying de-icer etc for the wifes car, I picked up a spare tube from their cycle section. It turned out to be a long, non threaded valve type. Thought no more of it.
Puncture on the way in to work Thursday morning 05.30 (minus 10 degrees the guage said). Fitted new Halfords tube ok but when I unscrewed the Co2 adaptor after inflation, the whole valve core came out, instantly deflating the tyre again! Replaced the core and tried again with the second cylinder, only to get the same result.
Never had this problem with the short valve tubes and don`t know if this fault is specific to Halfords long valve tubes or whether most/all long valve tubes are the same design.
Needless to say Mrs merlin wasn`t overly thrilled to receive a phone call at 6am on a freezing winters morning, asking to bring me out a new tube and the track pump!!!!
She did come to my rescue however and is now anticipating something extra special from father X-mas.
