>>1111998Oh, for fuck's sake.. is it really necessary for you to sperg out so much over a simple question?
Okay then.. My TT bike has tubulars, which have latex tubes in them, so I damned well know that compared to butyl rubber tubes, they leak like a (molecular) sieve. Those have Stan's in them against punctures and I accept that over 24 hours they go flat. That's not the issue though.
I have literally had a tube blow out while I was riding, and the seam in the (butyl) rubber had split. No damned excuse for that.
I have literally had the valve-stem-to-tube-seal fail, *while descending a goddamned mountain*, because the rim got too warm. The only reason I'm not dead is I was coming to a stop anyway; if I'd've been carving through a curve at 40mph I wouldn't even BE here.
I bought a pair of Slime tubes before the last few road races this year, because I had a puncture in the middle of a race that I would have placed well in, and that killed the whole race for me; for what a goddamned Slime tube cost me, it should have been better quality than having the valve-stem-to-tube-seal fail *for no reason* (swapped it into another wheelset and it just started leaking). I don't even use the supplied nuts anymore so you can't blame it on improper installation.
I've had otherwise perfectly good tubes go straight into the trash because the non-replaceable Presta valve cores weren't replaceable, and the damned things were slowly leaking (as verified by dunking in a sink full of water). There's $6 down the drain..
I've even had problems with actual name-brand (specifically: Continental) tubes have problems like the above, and you pay a premium for those by the way.
More below (because I'm a wordy bastard)
