    Switching from tubes to tubeless...

    I have been biking for a few years now and have always used tubes underneath my tires. I am in the process of building up a new bike for myself and I am thinking of making the switch to tubeless. My friend has tubeless on his XC, but my knowledge of them is pretty limited. I know he has that weird goop stuff inside his tire, and I know they are a helluva lot lighter than my wheels.

    So, school me on tubeless. Whats the mounting/dismounting process? Easier/harder to fix on the trail? What does a beginner need to know?

    Thanks!

    www.notubes.com has a lot of information on tubeless. I really like my tubeless set up, the fact that I can run mud tires at 25 psi is kind of cool (I'm 135). You do have to use the sealant in the tires. Mounting them is not significantly different from a regular tire. I sometimes see people complaining about tubeless on here but I really don't know what their deal is, I have had a very good experience so far.

    In saying "not significantly different" I meant it as it's not like mounting a clincher vs. mounting a tubular. For me, on my tubeless specific rims I just put the first bead on, put the second bead on 80% of the way, dump the sealant in, put the rest of the bead on and then inflate.

    edit: I just watched that video, damn I'm glad I don't have to really do any of that crap.

    Stan does it differently.

    You can get an injector offered by Stans(around ten bucks) that will let you put the sealer in thru the valve. It is way cleaner than mounting a bead, mounting the other bead, mostly, and pooring the seale thru the hole.

    are you doing it because everyone else is? i never flat. never. i ride ga's rockiest, rootiest trails and never flat. there are pros and cons all the way around. yes, you need the goop. and then you have to add more a few months later. and then...reprise. and then if you switch tires (if yer one of those who changes tires a lot it's going to get really old), you have to fight the goop mess again. it won't repair sidewall tears and if you get one of those 8 miles from the car, well, be sure to carry a tube anyway. and a clif bar wrapper. and stans will rupture and bubble certain tires.

    now, if you tend to flat a lot - it's probably going to be well worth it and the weight savings is a bonus. and if this is the case, so a searc on mtbr (or maybe even here) for homemade tire sealant. you can make it for pennies on the dollar as compared to buying the stuff retail.

    do the research, evaluate why you want to do it, and make the right choice.

    I hate to say it as well, however in all my years of MTB riding, I have never flatted or pinched flatted either. However I'm sure I just jinxed myself by expressing that

    On the road (road bike) I had gone +8 years with out a flat, then all of a sudden last year in one month, I got 6 flats, 2 were on my MTB commuter


    That said, I bought UST rims incase I decide to go tubeless.

    I basically want to go tubeless to save the weigh for climing. Its not gonna be as much of a pain in the ass as that video right? haha.

    I would most likley just install tubeless at home, then bring tubes with me on rides incase of a flat.

    Going tubeless does not save much weight. Better off finding some lighter tires. I use tubeless(UST rims) because I can run low pressures, that would pinch flat a tubed wheel, to get great grip and less bounce.

    Do tubeless tires really not save that much weight. I'm not sure exactly how much a typical tube weights, but that's at least 100 g per tire. Are tubeless tires heavier?

    The fact that the weight loss is on the wheels makes a huge difference if you have front or full suspension. Shaving weight by losing the tubes makes it easier for the suspension to keep the wheel on the ground, greatly increasing traction and control.

    I switched an 06 Epic, went with full XT wheelset, Approx- 250 grams lighter than the stock ones. Added the specialized tubeless S-works tires with sealant. When all was said and done, the bike weighed the same as it did stock. If there was 50 grams difference, I would be surprised. Could have made it lighter by using standard tires, ( which I normally do, but don't recommend it for bigger riders) .

    For me it's about not getting flat's, and very little rolling resistance at low pressures. I don't anticipate going back to tubes anytime soon. Last fall I picked up a thorn from a locust tree. It was 4+ inches long and went through the bottom of the tire and was sticking out the sidewall. I pulled it out, heared a small pfft of air and sealant, and that was it! Didn't, and haven't, added air to it since.

    I dropped a quarter lb by going to stan's system. All in rotating weight.

    If you're building up a bike from scratch, go with UST rims and a good set of UST tires with stan's sealant. I really like my stan's conversion, but mounting new tires can be a bit of a bear for a first timer. Luckily I don't switch out tires that often.

    I'd agree with others on the weight issue....you're not going to save any significant amount of weight by switching to tubeless. that being said, do it anyway.

    the real reason to switch to tubeless is to run your tires at a much lower pressure. what this does is give you much better grip. i have been running tubeless on my xc racer for about a year, and noticed a significant improvement, especially in climbing. concerning flats, I've never had one, even though I run standard (not UST) tires on UST rims. even so, I always carry a tube for extra measure.

    So, while you are looking to reduce weight in order to climb better, I would instead switch to tubeless to get better traction on a hill climb, and worry less about the weight (provided of course, that you don't increase your weight!).

    short answer: regardless of your reasons, you probably won't regret the switch to tubeless.

    Sure as Hell, as I was leaving work today, my back studded tire on my commuter was flat! Honestly, in the winter? What a drag!
