    If the bead stretched on your Piranhas, then you probably didn't have the most current version of the tire. Curious, but how did you set up your A23s for tubeless use, just tape or with a rim strip?

    I've got three sets of tubeless A23 wheels, all using the Stan's std 26" rimstrip, and whether I've run Bulldogs, Piranhas, Happy Mediums, or any number of tubeless ready road tires on them, I have not had a single lick of problems with them.

    If you're not using a rimstrip, try the std 26" strip. My guess is all your problems will go away.

    Everyone warned me that tubeless was a no-no for cross, but I'm glad I tried it for myself. Many probably don't want to believe tubeless is a valid replacement for their pain in the @ss tubulars that are superior by a seemingly decreasing margin. Component choices (rims, tires) seem to make a bigger difference as to whether tubeless will work consistently, although I'll be able to say that more confidently after I have an entire season on them under my belt.
    I say this with a completely straight face, you are not fast enough to realize the superiority of tubulars.

    Well, I know this is true for me.
    The biggest obstacle for me to go to tubs is tire pricing, and needing another set of wheels. I'm a mid-pack 4, racing singlespeed in an area that has no separate singlespeed cat.
    There's a lot I could do that would make me faster than tubs.
    I rode and raced tubs in the 90s on the road, and completely understand why tubs are superior in CX, I just can't justify the expenditure for a hack like me.

    Clement pdx tubeless on stan's 340 rim at 45 worked great for a half lap. Took a g-out as if i was on the mtn bike (didn't want to endo). BOOM

    That was a long walk back to the pits to get the other bike

    I had a hard time sealing those tires up. Worked great on girlfriend's bike but my luck with them was obviously not the same. I was burping them in warm ups. Damn i wish i was 50lbs lighter haha

    dt tk540 rims, 2 layers gorilla tape, stans valve.
    i aired them up with a compressor, but no sealant. the bead set fine. i took out the valve core and put in sealant the clean way and aired them up again. holding the wheel sideways while pulling on the bead around the tire will really help to seal any potential leaky spots. they hold air for weeks no problem.

    the ride is good. i have had them as low as 33/35 but thats generally lower than i would run here in texas, given the rocky nature of many trails. i also have 32/36 spoke wheels (they still make those??), so its really fun to barrel through **** most wheels would cringe at, knowing that i a)wont fall over b) wont pinch flat and c) wont break my sh!t.

    cant really speak to the weight, im not that guy.

    been tubeless on the mtb for years, im never going back to tubes for cx now that tires like this exist.

    Here is my experience with tubeless cross:
    I weigh 150 lb and have been racing cross for over 10 years. I'm fast but not super fast.

    This year I bought Stans Alpha 400 and mounted them tubeless with Michelin Mud. I just used the yellow tape. They surprisingly did not mount with a floor pump but aired easily with a compressor. 1 scoop of Stans.

    I did 7 races this fall and mainly ran pressures about 27/28 psi. Twice I went with pressures at 25/27 psi.

    The first race I burped my front tire on the last lap and had to run it to the finish. But I crashed hard on the last lap and not sure if I that caused the burp.

    After that, I never totally trusted the system but I must admit they worked great every other race. And the Michelin Muds were great all season. Good on the hard pack and good enough in the little mud we had this season.

    27 psi feels so much softer in cross than mt bike. Unbelievable difference. With the squeeze test they feel way too soft but once ripping over hard, bumpy grass course they feel great. And they do ride different at that pressure than mt bike tires. I think one has to know they'll feel a little wiggly and put up with that for the float and traction benefits.

    The Alpha are not the stiffest rim. I rode a teammates bike for one lap this fall with HED Stingers tubulars and they blew me away. Stiff, precise with great float. But for the money, the Alpha tubeless are great.

    Another benefit; I can train/race on the same wheelset. I never could do that when I used tubulars. For a 45+ Masters racer with not enough time/money this is a huge benefit.

    An extra plus is I can set them up in 20 minutes. I glued tubulars a few times and really, really disliked it. And when I looked at new tubular tire prices this past August, I just couldn't do it.

    No, they are not as good as carbon tubulars but for the price/convenience/performance, I will probably use them again next year.

    After a couple flats I decided to move forward using my Bontrager Rhythm Comp wheelset that I was no longer using. My 700x40 Kenda Happy medium mounted up with a floor pump w/o issues.

    The 700x35 SB8 is being a pain in my ass. I couldn't get both beads to seat. A friend suggested I seat both with a tube, carefully pop one bead, remove the tube, then proceed with tubeless inflation attempt. Still couldn't get it to seat with my floor pump. I have a compressor...but my inflator tool broke. Think I can get the one to pop on with a compressor so I have to go buy another inflator.

    But I've read a lot of warnings about converting non-tubeless road tires to tubeless, because the tube actually helps press the tire's bead against the rim's hook. A non-tubeless road tire's bead will stretch under the higher pressure, and without the tube holding the bead in place, a catastrophic blowout will likely happen with typical road tire pressures (roadie wrench Leonard Zinn talks about it here).

    Non-tubeless mtb and cross tire conversions usually doesn't have the same problems because the pressures are much lower.

    I like the idea of being able to mount higher pressure road tires on my cross wheels in the off season, since my cross bike is my only road bike currently. I emailed NoTubes about using higher pressure road tires on some of their cross oriented rims, and got this reply from Peter Pelychaty:


    You cannot use road tubeless tires with the Iron Cross because they are too tight. You can use road tires with a tube, but we recommend staying under 90 psi, especially with the larger road tires because it can slightly shorten the life of the rim. The Arch EX is a good choice, but it also cannot be used with road tubeless tires, but only tube-type road tires. We can make you a custom Alpha 400 wheelset...


    Until Hutchinson's Intensive 28 road tubeless tires become available, I'm still a little curious (and a little cautious) about having some fat tubeless road tires. So Deeps, have you had any problems with your Pasela tubeless conversions?

    Which Pasela model (ie width) have you converted to tubeless, which rims have you used, and most importantly, what pressures are you using?

    Thanks in advance!

    I was able to get the SB8 mounted on the Bontrager rim with a new blow gun attachment for the compressor. Battling some tiny bead leaks still on both tires. Going to throw an extra scoop of Stans in each and go out for a ride to help seal them up.

    I have been running Michelin Mud2 tires with Mavic Askium rims and Stan's rim strips. I have been running 28 psi front and 32 rear. I have raced them all season and even ridden them on single track. They have been working perfectly until Saturday, during practice before a race, when I went off of a small drop to an off camber turn. The front tire burped all of its air, the rim stuck into the dirt and I went OTB. I noticed afterwards that the inside of the tire had very little Stan's sealant left. I am not sure if being low on sealant caused the problem but, I am no longer as confident with the setup.

    It is 4 weeks since the last post - here is an update to the "wire bead tubeless".
    I was riding A23 with wire bead Clements for another 4 weeks, 2 races and probably 50 MI of MTB singletrack at 27F, 34R verified by Topeka digital gouge (I am 195 lbs after Christmas). I think if this setup can be burped by now it would. Had one crash and badly damaged rear wheel, getting the tire off the bead was very difficult.

    Question for everybody - Anybody tried wire bead road tubeless setup? All they claim for road tubeless bead is that it does not stretch SO -> the wire bead may do the trick for 1/4 of the price??

    My LBS does a lot of tubeless and consults with Stan about what works ( we are in Ithaca, 30 miles from Stan's facility in Elmira), and says most wire bead tires will work, but not folding (kevlar bead can stretch apparently). Must have a smooth bead seat, not ridged like you see on some tires, and no skinwall.

    is that a response to Bo_vk? if so... then stan's website is outdated as it says road tubeless specific must be used. AFAIK, there are no wire bead tubeless road tires

    For liability reasons, no manufacturer, including Stan, will endorse tubeless conversions for wire bead or other tires if they were not intended for that purpose. And Lennard Zinn on the Velonews site has cautioned riders from converting regular tires and running at high pressures (90psi+). But many people have experimented with different setups, at their own risk of course. I can only speak for what works for me.

    Should have quoted bo_vk for more clarity.

    Hi everyone,

    This is my first post, I and arrived here trying to find information about going tubeless in my brand new cx bike, a Cube X Team.
    I regularly use it as an all mountain, not competition yet (cx season is over in Spain).

    So, after reading lots of threads, I decided to go tubeless, and the first choice was to buy a specific tubeless pair of wheels. My choice was DT Swiss R1800, because they were at an excellent price. I have not read so much of this wheels, but I swear it will work for my purpose.

    Now, my doubts are choosing the tires. I would prefer going again to specific tubeless tires, but the options are very limited, and I've read good reviews using regular clinchers. If I go in that way, does anyone now if Maxxis mimo cx is a good choice? And the most important, do I take the wire or foldable version? And at last, with a non tubeless clincher, do I need to use some tape in the rim?

    Thank you very much for your answers, and happy trails!

    Experiences with Mavic SL and Alpha 400

    Vittoria's are a breeze, on both.
    My wife's commuter (Alpha 400) and Clément USH were a pain to get airtight, in the end had to resort to NoZisch, after 3 weeks of battling with NoTubes.

    I'm running alpha 400's with continental CX race (700x35 folding model) with a stan's rimstrip on top of the tape.

    Had them burp once at ~27 psi while pre-riding a race course, then had the tire blow off the rim while taking a very tight turn on pavement on my way to work at ~55 psi. Admittedly the 55 psi was probably pushing it, but I do like to run at higher pressures on the road so I have a tube on the front for now.

    I think I'm going to make the jump to a tubeless specific tire soon - I had some trouble getting my front tire back on even with a tube. The bead was very stretched out, making it almost too loose. This makes me think the bead wasn't really strong enough to run tubeless (at least at a very high pressure). Hoping a stronger bead will help me run higher pressures on the road without issue.
    Yeah I only carry cans cause I'm a weight weenie.

    Any experiences with the new TCS rims from WTB with cross tires? Specifically I'm looking at the I19 and want to run them tubeless. I emailed WTB, but they were pretty useless. I dont have the cash to buy the rims and build the wheels just to test out some combos.

    I had a pair of MiMos for a while, and they were pretty loose on a few different rims. I doubt they'd set up well tubeless.
    You may want to check out the Vittoria XG TnT, or Specialized's 2Bliss Ready tires.

    Thanks sslos.

    Yeah, I also agree the best way is to go for a specific tubeless tire.

    Kenda Kommando, Vittoria XG TNT & Spe Captain 2bliss are my options, but they are hard to find. Which one will you prefer for hard pack, rocks, dry trails?

    Hmmm, I have not ridden any of these in those conditions, but judging from the tread I'd say the Spec.

    Impossible to get the Captain's 2bliss in Spain.

    Vittoria TNT and Kenda Kommando or Small Block Eight SCT are the last options in tubeless tires. Not sure if a non tubeless tire will work on my DT wheels

    I like the SM8 in hardpack, rocky terrain. Terrible if there's grass or any moisture, so they didn't work for me for CX.
    I set mine up tubeless with some difficulty, but they did work.
    Unfortunately, the sidewalls are a bit delicate. I sliced the rear fairly quickly, 1 cm gash that hasn't really patched well enough to keep them tubeless.

    Did you use the SCT (sealant compatible) Kenda tire or just the normal version? Which pair of wheels did you use? Stan's?

    Has anyone experienced going tubeless on DT Swiss R1800 wheels?

    Standard (non-SCT) tires, Bontrager Mustang rims, Gorilla taped.
    The SCT version wasn't available when I got them, and after one CX race on the SM8s I won't spend the money. I liked them pretty well for singletrack duty, but they were terrible in the grass-heavy CX courses we have here in Idaho.
    If you're not racing the SCTs might be a viable solution.

    I'm trying to set up my CX bike as tubeless but having just bought a new roadbike and MTB, funds are a bit low!

    The routes I ride tend to have a lot of thorns around the trails so punctures are a common problem. I'm hoping to cut down on the punctures if possible.
    Instead of going for new wheels and tyres, I'm planning on fitting a set of Schwalbe tubes with removable cores then putting some Stans sealant into the tube to see if it'll help with punctures. Has anyone tried this and did it work?

    Yup, that's pretty standard in CO with all the goat heads we have. I even put a little in my road tubes. Cheap quality brand tubes also have removable cores.

    Excellent, thanks for letting me know.

    Out of interest, how much sealant do you use in the tubes?

    Worked for me too. I used the QBP tubes which, as mentioned, have the removable valve stem. For my 700x35 tires I believe I used about 1.5 ounces per tire. I've pulled multiple thorns/goat heads out of them after races without much air loss, so they do work well. I don't think they are pinch flat proof though. I have been trying to get motivated for tubeless , even have some stans alpha rims, but it seems like different tires are hit and miss. I had some Maxis mud wrestlers set up beautifully only to have them blow right off the rim riding down to the park to test ride them. After seeing and hearing other scenarios like this, it is hard to beat tubes and sealant. I mean what’s the point of saving a few grams if your not even going to finish the race. So I that note, has anyone had luck with the continental X-kings tubeless? I like the looks of the 700x35’s, but heard the side walls are rather porous.

    Since this post I installed Hutchinson tubeless road tires on my bike so I felt an explanation may be in order. I still feel the wire bead road tires would work tubeless. It came down to the risk / benefit feeling. As I was looking for wire bead road tires I realized they may not be made in needed quality to keep the wire from separation from rubber at high pressures (several people actually mentioned this in tire reviews). So I got the real tubeless road tires and sure enough, the build quality is visibly excellent. For road where there is so small margin for error I will stick with real tubeless.

    On the other hand I still like wire beaded tires for CX (low pressures).

    Any experience with these tubeless

    Vredestein Premiato Cross Tire? Would be going with the 700X34 on a Stans Alpha 340.

    Nope. I don't think they are tubeless ready... so you may need a rimstrip.

    ALPHA Cyclocross Rim Strip

    if that's too expensive... then there are the proven ghetto tubeless methods to try

    Thanks for the response. I thought for the stans alpha set-up that a double layer of yellow tape was all that is needed, or is this for Road tubeless? I did set these wheels up with some Maxxis mud wrestlers (New old stock 700X35s). They set-up and held air beautifully but blow right off the rim when riding to the park. These were really loose fitting and I found out later people were not having success with these. So with a tighter fitting tire would I still need a rim strip? or is it mostly trial and error still at this point in cross tubeless?

    The majority of cx tires will fit on the Alpha rim and can be used tubeless. There can unfortunately be large variance in tire size. I have seen sets of Muds that are loose and others there were tight. A tight fitting cross tire will work well with just the yellow tape and valve. For a loose fitting tire add the alpha rim strip. http://www.notubes.com/ALPHA-Cyclocross ... 91C13.aspx

    Double wrap is mandatory for road tubeless due to the high pressures for road tires.. Optional on cross and mtb. Going double doesn't hurt.

    Specialized Captain 2BR set up just fine with 1 layer of Stan's type on Alpha 400.
    Specialized Bicycle Components

    on my MTB.... I had to use 2 on my Arch EX rear wheel with Specialized Renegade Control. The front Arch EX was fine with 1 layer with Specialized Captain Control (both are 2Bliss ready)

    tubeless ready (non-UST) would also have an extra butyl rubber layer on the bead, to help with sealing. So, non-tubeless ready tires, this is why you can use a rimstrip to take up the slack. There are other methods also, ie build up with rim tape, gorilla tape, extra tube, etc.

    Re: CX Tubeless setup thread

    Decided to end my conti experiment last night (CX race 35s on alpha 400s). They were a GREAT off road tire but didn't deal well with even moderately high pressures, and felt squirrelly on the road with lower pressures on such a narrow rim. Sidewalls were kind of porous, and didn't recover from punctures too well - the last straw was coming out of work to a flat and having to ride home with maybe 10psi worth of co2 left. These will go on my B wheel set which may end up getting sold to my brother if he gets this sweet lemond frame he's been eyeing.

    LBS had some Vittoria XG TNTs lying around so I dropped my bike off to get them on. Hoping for a stronger bead so I can run at least 50 psi on road without fear of blow offs and a better sidewall. Will report back.

    Vittoria should be no problem.
    Have been way over 50 psi with XN (on Alpha's)

    Re: CX Tubeless setup thread

    Good to hear - my mountain bike is in the shop and we got some nice weather this weekend so I'll be testing these bad boys out on the road tomorrow. May try as high as 60 psi if I feel cheeky.

    Construction on these tires feels impeccable. Supple sidewalls, really strong beads, went up tubeless no problem without the stans strip. Only concern is that I'll chew through the tread too fast on the road, compound used feels very soft. But I'm tirewilling to replace tires a bit more often in exchange for a more robust tubeless setup.

    **EDIT** these tires feel great on the road - pumped up to 65 in the rear and 60 up front and was rewarded with a very confidence inspiring ride (actual pressures may have been higher not sure how much confidence I have in my pump's gauge). Saw they are rated for 45-90 PSI - I think 45 was about the maximum my old tires could handle with a tubeless setup. Hope they don't have any issues on the occasions when I want to go lower, but with such a supple casing 45 might actually be low enough. That soft-feeling tread compound makes for some amazing grip too. Can't wait to get out on them again.

    Experienced a blowoff from a Clément X'Plor, whereas the Vittoria was still going strong, I measured with a digital gauge the Vittoria @ nearly 5,7 bars ~ 80 psi, the Clément was long gone ... I still have my garage ceiling painted with NoTubes :-)

    Never trust your old pump gauge ....

    I will share my experiences from this past season. I initially started off running Maxxis Raze both front and rear on DT Swiss 1850 rims with wide rubber 26 inch rim strips (2 on each rim for thickness). They both aired up very easily but I experienced 3 or 4 burps during races this year that cost me several positions (cat 4 mid-pack glory) and decided that something had to change on the front. I never experienced any problems with burping on the rear. I was running high 30s on the front and low 40s on the rear.

    I switched to a Maxxis mud wrestler on the front and it has served me much better. No burps in any CX races. I did get a slight burp this past weekend while riding 12 miles of singletrack at the Doubleshot race here in North Carolina. The burp was very slight and was easily pumped back up. The course was very rocky and rooty for skinny cx tires.

    Overall I think the Raze has too loose of a fit to work reliably for ghetto tubeless in CX. Maybe people using a proper rimstrip or Stans wheels would have different experiences.

    Next year for CX racing I think I am going tubular but tubeless is still a viable option.

    I'm planning on doing a CX tubeless setup with Stan's Crest rims (which were recommended to me by Stan's for my custom hub and spoke choices).

    I'm interested in the Vittoria TNT tires, but have heard from a guy at my LBS that they can be terribly difficult to mount. For those of you that run these tires, what did you think of the installation?

    Also, has anybody tried the Stan's Raven tires tubeless? Any details on those would be great to hear too!

    I've had the Crest rims on my crosser since last spring. Currently have allrounder tires on now (Serfas Vida, not tubeless-specific but work just fine). Will put on the Ravens that i have been saving for mud season. used those ravens on my DT Swiss wheels w/Stans conversion but not yet on the Crests.

    Ravens are great tubeless - that is their purpose. Had one sudden leak that resealed itself in 6 mos. of riding (finished the ride w 10 lbs of air). you can't go wrong with Ravens on Crests. The great thing about Crests (and all Stans wheels) is they will allow more standard tires to be used tubeless because of the tighter fit. Also means that changing tires can be a bear.

    The Arch EX on my MTB... seating the bead is a PITA.

    the Alpha 400 on my Cross... super, super easy. I can seat the bead by hand with tubeless compatible tires

    Re: CX Tubeless setup thread

    Vittorias definitely tight - shop had to remove my rim strips to install. Once on they go up easy though. The tires that go on easy seem to be a bit less reliable.

    Haven't had to pump them up since first ride - haven't had that with any tubeless setup and its pretty lovely. May look for a TnT tire for my next MTB setup to see if they hold air as well.

    Just mounted a pair of Clement LAS on Stan's Iron Cross. Tires seeped a bit. Added some Sealant after a couple days. Got in a nice gravel ride on them and they feel very quick.
