PERFORMANCE TUBES???
OK-I love spending $2 on tubes, but I'm starting to think I get what I
pay for. When Performance tubes are on sale I pick up a dozen or so, other times I pick up Contis or Torotellis or Ritcheys (pardon spelling, it is late) when they are on sale--though they are never as cheap as Performance Tubes. So I usually use 2 Performance tubes to 1 brand name tube. Use two sets of wheels equally. This year I've had 3 valves pop off/ fail at the casing (at the base)-twice when being inflated and removing the pump head-once when just laying in the back of the car (slow leak from base after ride.) All 3 tubes-Performance. Hmmmm. Any validity to my hunch that Performance tubes, esp. where valve meets the tube, may leave something to be desired. |

Back when I exclusively mountain biked, I had very good luck with Performance brand tubes -- even the lighter types (like Lunar Light and Ultra Light). Lately with P-brand /road/ tubes, however, I've been less than pleased. The standard weight ones are OK I guess, but the lighter ones have either failed like you describe (at the valve) OR right out of the box with pin holes (twice!). At least they took 'em back and gave me new ones; haven't installed them as yet. For my money, Michelin Race Lite tubes are the best in terms of moderate cost, light weight, and decent durability. (Trek brand tubes pretty good, too.) YMMV, BS |

I've had three Performance 700c tubes (just their standard tube, not any of their super light models--haven't tried those, don't want to) fail on me in the last couple of years, all at the valve stem where it meets the tube. Fortunately, all three have occured while the bike was just sitting there after (or before) I was going to take it out on the road, or once while I was actually pumping with a floor pump. I suppose it could be the tube, or my pump attach/detach techniquze. I've had better luck so far with REI's Novara brand of tube as well as other, "no name" Taiwan-made tubes. I haven't tried any European brands. -- I do not accept unsolicited commercial e-mail. Remove NO_UCE for legitimate replies. |

I bought the 3 for something about 5 years ago, and I may have to order something from Performance to get some more -- I used the last of those three this spring. No real issues with the tubes; as I recall, I punched a tire lever through one, tore one stem off (that could have been user error OR faulty tube), and couldn't patch the other one when I got a leak right next to an older patch. So no, no real problems with that batch. Later batches might have different stories. Pat |

All 3 tubes-Performance. Hmmmm. I've not used Performance tubes, but I had the same problem with Specialized 700x20c-28c tubes. I think I lost 5 or 6 tubes that way in the first year. I would have given up on the tubes except for the fact that I'd bought a pile of them on sale, and they are the smallest tubes I've found which claim to be a fit for 28c tires (so I can fit an extra spare in my seat bag). I've not had a similar failure in over a year, however, since I began throwing away those knurled valve stem nuts and installing the tubes without them. I think I've had only one flat on this bike since I chucked the nuts, and that one was caused by a tack which came through the tire. I'm not sure how (or even if, to be honest) the valve stem nuts could cause this failure. I'm almost positive I wasn't over-tightening them, I'm paranoid about not being able to get the nut off by hand after a flat and so I would check that the nuts were just barely finger-tight even time I put air in the tires. What I've observed about this particular tire/rim/tube combination, however, is that no matter how hard I try to get the valve centered over the rim hole and the tube stuffed evenly into the tire all around, by the time I get the tube inflated to full pressure without the nut the valve almost always ends up cocked over at a bit of an angle. This didn't happen with the nut on the valve, of course, since the nut forces the valve to come straight out the hole. Forcing the valve straight will necessarily be accomplished by stretching the tube at the base of the valve, and I guess this extra stress at the base of the valve could contribute to the demise of the tube. In any case, you might try and see if the tubes last longer without the nuts on the valve stems. Dennis Ferguson |

I've had a couple Performance tubes fail in the same fashion. Since I've been changing inner tubes for 30 years, I don't my technique is at fault. The local Performance also sells Bontrager-branded tubes. These have been fine. Jeff |

I bought 10 for a bit less than $20 a few years ago. Two or 3 had
actual punctures. The rest all failed at the base of the valve... Jay K wrote: OK-I love spending $2 on tubes, but I'm starting to think I get what I pay for.

I had some Performance tubes two years ago and stopped using them after
valve-stem failures, and had the same problem with Michelin ultra-light tubes. They are such crap I use 'em as bungees to tie things up with, never again to ride on. For my nickel the best value in road tubes is Kenda ultra-light. I first tried these 5-6 years ago and they've proved extremely reliable on all my roadie and fixie bikes. I prefer U/L's because they save weight and roll up more compactly. |

Another use for them... I have this cat that insists on chewing cords.
They make great conduit! Mike Yankee wrote: I had some Performance tubes two years ago and stopped using them after valve-stem failures, and had the same problem with Michelin ultra-light tubes. They are such crap I use 'em as bungees to tie things up with, never again to ride on. |
