Now that was scary...
riding a nice long downhill stretch at about 80 (50mph) and theres a funny noise, all happened in about 30 seconds. clunk clunk clunk, wondered where it was coming from, stopped pedalling, no not bottom bracket, clunk clunk, then HISSS, (rapid deflation) then flub flub flub noise as I try to pull up safely.
What a rush.. but something I don't really want to repeat.
Thought I'd be fine with my Armadillo's, searched all over.. no puncture. Pulled the tyre off and theres a hole in the rim side of the tube. No damage to the tape, no spoke sticking through. Anyway fixed it and made the 20km ride home on a half inflated tyre, got to get me one of those CO2 inflaters!
Took it to my LBS and yep, faulty tube. They replaced it no charge and trued the rim (it took a little beating). I'll keep going back there, bought a new tube so if anything nasty happens again I wont have to use the repair kit. Next LBS stop is a CO2 inflater (when I get the ok to spend 'more money' on my habit)
