Really, if flats are not a big deal, then dealing with latex goop, buying special tires, pumps, valves, rims, etc. is not attractive. If you live in goatheadville, then it is. I might give it a whirl, though -- right after I get done cleaning my chain. https://www.sheldonbrown.com/chainclean.html -- Jay Beattie. |

Let me ask you again - why do you suppose that every other rubber tired vehicle has changed to tubeless? Even when I do loaded (40 to 50 lbs of gear, food and water)touring for two weeks or so on dirt/gravel/trails in northern Ontario Canada I get very few flats in my 26" x 2.125" tires with INNER TUBES. Most trips I don't even get a flat. Why in the world would I want to mes with something that can be so hard to repair? All I have to do if I do get a flat is pull out the flatted tube, check the tire for any debris that has caused the flat and then install the new tube and pump the tire to the pressure needed. Then I can take my time in camp and repair the punctured tube. Tubeless might be okay for some to many of us tubless is an answer to a problem we don't have. Cheers Yeah like I said we’re in to August and I’ve had one flat this year. Took 5 minutes to replace the tube and fill it with co2. Most seasons I get 2 or 3 max unless there’s some anomaly. Usually due to pot holes on crappy Quebec roads. Don’t remember the last time I had a puncture flat. I was using Spec Pro tires and now Conti GP 4000s. Both have flat protection that seems to work. -- duane |

Cheers In fact, except in unique situations - like the goat head thorns - I suspect that flats are really pretty rare. At least on road bikes. Riding in Bangkok my average is less then one a year which is hardly enough to notice and it takes 5 to 10 minutes to change a tube, which makes actual lost time due to flats in the neighborhood of 3 or 4 minutes a year. Hardly worth fooling with all the goo and gore to run tubeless. In fact, back when I was running sew-ups I had very few flats but of course it takes much longer to repair those :-) |

That's way more than average. But it's still nowhere near the threshold that will cause me to switch to tubeless. Each flat took me less than five minutes on the road, and less than ten more minutes to patch the tube at home. -- - Frank Krygowski |

Speaking of weight, just how heavier are these tubeless systems compared to the old tyre and tube system. You are perfectly free to feel that the same technology used on every other rubber tired vehicle in the world is not suited to bicycles but if you're going to argue, don't use inadequate responses like "lock you in to their products" or "testing procedures are only for very narrow test conditions." when this isn't the case at all. It is far easier to test bicycle tire performance than those of a motorcycles. +++ How many of these "every other rubber tyred vehcicles" are not driven by an ICE or similar power plant. P.S. you can leave out shopping trolleys. . Why are you arguing this? Tubeless tires are missing the weight of a tube. What's more, because the sealant is so reliable you can use lighter racing-style tires rather than armored tires such as the Gatorskins or the others of similar construction. The flat tests I presented earlier was a guy riding Continental 4000's - a racing tire that has minimal rolling resistance in the tests. |

It plainly states in that article that they don't have tubeless tires because of the expense of upgrading to new style tires and rims. If your argument is based, as most here appear, to be that you have an old bike for which conversion would cost more than the worth of the bike why the hell don't you argue THAT instead of using the phony arguments that they would be difficult to repair if you got the same sort of flat that would also make a tube tire worthless. The dumb-ass comment that you could fix one of these slashed open tires with a candybar wrapper is pretty inane. Or the claim that they don't get as good a performance when even the testing shows the theory of rolling resistance being less on a tire with less mass to e true as it is in every other case. Look, I've been riding for 40 years. I've had a lot of flats. I have never successfully repaired a slashed tire with either an innertube section or ever found a candybar wrapper that would possibly hold anything together against the inflation pressure of a high performance tire. As a sailor I could also repair sails with heavy needles and nylon string. I'm pretty sure you could sew up a tire well enough to make it home against inflation pressure but again - that would work equally well with a tube or tubeless tire. Since Joerg complains of sidewall slashes from the way he rides I could understand his arguing against it. But 10:1 his sidewall failures are punctures that a tubeless setup would allow him to continue riding. |
