    More supple, less puncture flats, can run lower psi without pinch flats, less rolling weight, less $ on tubes.

    The only con I can think of is not being able to swap tires quickly.

    The search feature (more like "search failure!") is difficult to use well for me.

    Depending on your fatty tubeless setup/scheme.......less rolling weight is not an attribute of most tubeless fatty setups. FYI IMho FWIW YMMV LOL

    Less rolling resistance than tubes IS an attribute of tubeless> (though I am not sure we have quantified the data) (search function for that???) .

    I find that it's much easier to type in "use the search feature" and add to my post count, than it is to actually be useful in a post.

    I'm also looking for a truly compelling reason to try tubeless, and I've yet to see it, plus I'm now subscribed without having to use that painful Subscribe to This Thread button.

    not only that but the PSI is identical along with weight. and what do tubeless folks do when they do flat due to a puncture? install a toob.

    Nope.. Lower pressure with tubeless, half a pound lighter and IF I get a flat dunno, never happened but might just use stans and pump..

    You know what helps make the search function work better? Spelling the most important word in your post title correctly. Hmph.

    I've been mountain biking for 25 years, fatbiking for almost 3, have a fleet of bikes, do my own builds and repairs and I've never run tubeless, ever. Always been curious, but never compelled to do it.

    My biggest reason for not running them on the fatbikes us that no rims and tires are designed to be tubeless yet, and I don't trust the so-called ghetto tubeless techniques. I barely trust the tubed rim/tire products that currently exist. The QC on the tires is especially bad, with ridiculously loose or poor fitting beads, and out-of-round tires. I haven't had a tire come off at speed yet, but I've heard the tales, and they often seem to involve going tubeless.

    Also, if you flat while tubeless out in the woods, how do you get the tire seated again without using a tube? (I know, you don't) So now you have a tube. Are you really gonna swap that out when you get home? I wouldn't, cuz I'm lazy.

    I think I'll switch to tubeless when I stop seeing threads about the pros and cons of going tubeless.

    nope in either case sorry. Toobs can go down to 3psi with no problem and weigh the same or less. and if ya go any lower it's flat end of story so ya might as well huck it.

    Small puncture resistance and weight saving are the 2 major reasons, I read about lower pressures but my findings were opposite, I don't need the super low pressures so rim hits are a non event for me. If anything the more supple casing with tubeless got me pumping 0.5-1psi more in the big-ole-bags.

    Nevermind the cash, the time spent on my 5 attempts (2 sets of wheels) before I got it right blew the cost out of the water by 100:1

    Once dialled its a relatively painless process.... kinda

    I can't, the tyres start to slip on the rim.. so depends of the rim-tyre combo how down one can go. With tubeles no such issue..

    I'm tubeless on my fat bike and mountain bike because I'm lazy. It's easier to put in two scoops of sealant than fuss with a tube. I really hate interupting a ride to change a tube on a ride because of a pinprick puncture that sealant can handle with no problem.

    My primary reason for running my BFLs tubeless is the same reason that all my MTBs are tubeless- the tires conform to the terrain a lot better without tubes. The difference in traction and ride quality is even more noticeable on the 4.7 BFLs than on a standard 2.35 MTB tire.

    I use Fatback Uma 90 rims, which have a bead locking ridge for running tubeless. The BFLs pop onto the bead tightly, just like a Stans rim, and I have had zero burps since converting. All they require are sealant, tape, and a valve, just like a Stans rim.

    A lot of the "tubeless doesn't work with fat tires" talk comes from people having limited success with ghetto conversions (split tube, foam strips, ect.) on rims that were not designed for tubeless use.

    I don't understand why running tubeless makes swapping tires any more difficult.

    It will also reveal your disdain for tubeless. As someone else has asked, why do you even read threads about tubeless if you are so opposed to it?

    About $40 A small fraction of what I spend on my biking sport and it makes it more enjoyable because I don't deal with flats, ever.

    NOT. This event is so rare it isn't worth being prepared for it no further than most ride from civilization. But the tire can be patched just like a tube. My most recent 1/2" wide puncture has sealed just fine and I've been riding on it all summer.

    This is totally WRONG. 3psi will pinch a tube very easily. During the winter, 3-4 psi is generally my high, with 1-2 psi when the snow is difficult. The tire isn't flat but it does have a lot more surface area.

    negative on both counts so why read these threads when you want everyone to believe as you do?? 1-2psi is flat and has nothing to be gained over 3-4psi and i challenge you to come up with a quantitative measurement between the two.

    far more than what toobs cost and time to prep with all sorts of ghetto stuff. and yes you will get flats so stop pretending ok?

    There is a large quantitative difference to be experienced when riding on snow that won't pack or climbing in fresh snow at 2 psi vs. 4 psi. You challenge me? Someone already has and in one of the previous threads I did calculate the added footprint of the different pressures. But, I'll do it again.

    As far as switching tires, which by the way, I don't do often because I like to ride my bike, not work on it, I don't see the problem. The tire comes off the exact same way. Yes, there is "slime" in the tire but it doesn't make the tire change anymore difficult. Take the tire off and pour the slime into the new tire. Mount it and air it up. Actually, it might be easier because one doesn't have to deal with a tube which for some causes problems.

    Switching tyres is a pain in the a$$, it probably doesn't take much longer than swapping tubbed tyres over but there sealant everywhere and getting the tyre seated again to deal with.

    I have 2 sets of wheels, both marge lites with 183mm hope rotors and cassettes already fitted to each set, one with 4.8" buds and the other set with 4" HuDu's. So my tyres switch is dead easy.... just cost a bit to setup.

    There is no need to get sealant everywhere and if done well, putting air back in the tire isn't hard either. Mini, no, I don't switch tires very often. To me, it's a pain in rear to switch tires with or without tubes. I just don't like doing it. It's not that I can't, it's just not something I care to do. But, I have, and do. Yes, there will be some sealant that gets on the rim. Use a rag and wipe it off. You can't change tires without washing your hands anyways.

    CUJarrett, in the first few paragraphs of your description you mention that "...there are no dedicated tubeless wheels...".

    This is incorrect.

    Speedway Cycles, the designer/builder of the FATBACK frame and forks have their "UMA" series of rims. They go tubeless just like a Stan's rim. Just use Stans "wide tape" and sealant and air them up.

    It was mentioned earlier in this thread. It is a fact.

    I don't want to get into an e-argument, but I believe we are saying two different things. I believe Fatback/ Speedway rims can be made to work tubeless, as I have proven so can Surly Rolling Daryls, however neither website advertises they are tubeless rims.

    I verified this on Fatback and Speedway's sites.
    FATBACK Ľ 90mm Rims

    The closest thing to advertising the rims as tubeless is:
    "Secure bead lock holds tire tight even at low pressures", which is not the same thing as saying "tubeless ready".

    Overall I believe we are all winners as we as a community have proven that there are working solutions!

    Thanks for the feedback man!

    After you search it and read about Uma doing some rimming.... click on the IMAGE button at the top, its all clean and many wheel pics.

    CUjarret......peace brother!......but.....

    Arguments over semantics aside, I brought this out because your article could have mentioned the Fatback Speedway UMA as the viable tubeless solution it presents due to it's performance-similarity to a Stans Tubeless rim.

    UMA rims.

    Stan's rims.


    Stan's..........Stans-tape the spoke bed, throw on a tire with sealant, and blow.

    Speedway/Fatback UMA........Stans-FAT-tape the spoke bed, throw on a FAT-tire w/ FAT-sealant and blow.



    I hope that doesn't sound argumentative. It is a fact.

    also, others'........for realities-sake, let us not think that tubeless options save any weight over available inner-tube options.

    Peace! D

    gcappy, the other reason for me to enter into these discussions is so that I can get negative reputation from nvphatty. Maybe he's spread it around enough to do so again.

    So.. is there a consensus that UMA rims are better suited to being set up tubeless than say Surley rims for example?

    mtuck1.......I don't want to be the guy to tell you to go "do your homework"...or "...did you try to use the 'search function', dude?..." because I've been hasssled and told those things.

    But......there is a ton of info. of guys doing UMA's tubeless. There is a "Stan's Fat Tape" that is for doing UMA's.

    I'll wait for the rest of the "consensus-ers"...

    PS, I do not run tubeless....but......when running less than 4 PSI on 80mm rims with HuskerDu's and tubes I am hearing alot of squishing/squeaking/stretching-rubbery noises from my tires and I suspect it to be tube versus tire relative movement. There is no question that it is annoying and maybe even causing me to spend more energy to keep them rolling

    No worries... I am currently running tubes in Marge Lites but there is a tubeless method in another thread that simply uses a Clown Shoe rim strip to seal the Marge Lite and that seems very simple and light (compared to tubes). But I am also considering a set of UMA's as a second wheel set. Not sure which makes the most sense at this point.

    Stevo, inquire into shipping them here (maybe its changed). The Price of shipping a set of UMA rims to oz would near buy you a set of Marge lites from Jensons and ship for $28.
