[QUOTE="Colin, post: 172823, member: 1953"] Matty. Thanks for the above, glad to see we octogenarians are still usuing our grey matter, not to mention our bikes! However I think it likely that you have rubber innertubes, and real rubber ones do leak air a little all the time. Inner tubes made of Butyl and the like do not do this BUT I would always go for rubber as Butyl and like seem to deflate almost instantly when punctured, as they tend to split from a puncture point. Whereas rubber will hole from a puncture, usually/mainly without splitting, and thus deflate more slowly. MORE SLOWLY deflating at 60mph is very valuable, as it will give you time to stop, before you lose control I suspect pressure loss gets less after a few days simply because the pressure available to deflate is less. Check to see if you have got REAL rubber tubes and not something synthetic. What ever else you do keep on riding, and keep your wheels between the ditches [/QUOTE]
