Light weight tubes(8 posts)

I'm looking at tubes for race wheels next year - what do people know about the 50 gram Conti's or Michlin tubes? Are they worth the price? Noticeable weight reduction? Hold air well? Or, am I better off saving some money and going with something a little heavier, like the 68 gram Specialized tubes or lightweight Ritcheys? I've used both and know that they hold air better than cheap training tires and cost $6-7. Thanks for suggestions.

I used Continental Supersonic tubes (54g each) and Continental Supersonic tires (165g each) on Ksyrium SSC SL wheels on a Chisallo. The first day I had 3 rear flats on the same route I always ride. No damage to the tire but a hole in the tubes. I switched to a heavier tube 65-70g and not a flat in 1,000 miles - same route. I'm a 145lb rider.

I use for regular training the Michelin 70 gram tubes with the Michelin Axial Pro Lights. Plus, I've been using the for over 7 years. I've had 2 flats this year in thouasands of miles ridden. Very reliable otherwise I wouldn't use them as a daily trainer.

Do NOT under any circumstance go with the Lunar Lites sold by Performance with the advertised weight of something like 43 g. ea. They have a tendancy to spontaneously fail at the worst possible time and this can be very bad.

I've had a pair of Lunar Lites on my bike for a thousand miles with no problems. Infact, I've worn out a set of Conti 3000's without a flat using these tubes. I weigh 160lbs.

Where do you ride? My bad experiences have all been in the hills/mtns around SF Bay Area in the fall, which can be notorious for sharp things like Goat Heads. The funny thing is that many of my friends have had similar experiences and the tubes are completely shredded and unrepairable. Very unnerving when you front tire suddenly goes flat while descending a steep and twisty hill - to this day I still have no idea why I didn't go down.
ride on rough roads, will give Michelins a try, thanks (nm)BenR

My experience with light weight tubes has been that I've had more flats with them. I've had flats on the rimstrip side, for example, that should not happen. Now I've standardized on the standard Specialized tubes in the black box. Besides saving some money, I've yet to have a flat that wasn't attributed to something puncturing the tube (i.e., a thorn, wire, etc. ). The standard Specialized tubes are actually pretty light too but they're not stupid light.
