Hi All
Just wanted a quick sanity check. I had my first puncture last night in over a year of commuting - it was a slow puncture from a tiny piece of glass that I didn't notice when I carried-out my tyre inspection post-ride. Luckily I noticed before I cycled home in the evening and could change the tube in the comfort of my works parking garage.
However, when I replaced the tube and inflated the tyre using my Bontrager CO2 inflator (one where you can control the flow of CO2 via a valve on the chuck) I managed the blow the spare inner tube. I used a 16g canister so from what I understand I should be able to put the full contents into a road inner tube and it will inflate it to 120psi. However, the blown inner tube had split along the seam.
Did I do something wrong? Am I not supposed to put the full canister into the tube?
Or did I put the air in too slowly and the leave the chuck attached to the valve too long - as those things get pretty darn cold from the CO2?
Luckily I had a 2nd tube to hand and a hand pump that I used - not wanting to take the risk of the same thing happening again... The tubes were around a year old, have been in my saddle bag wrapped in plastic bags (to stop the rubber from perishing).
Cheers, Paul
