    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.

    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??
    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.

    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.

    Managed to blow the Vittoria off the rim yesterday (stans 400). I was at a hair over 80 psi (by my gauge, which may not be the most accurate). So will be keeping in the 70's in the future. This one was interesting because I was going straight - much different experience than the conti which basically tore off the rim coming around a tight corner. It was *very* loud too, people came running out of their houses thinking I'd been shot. I filled up in the morning, so I suspect that the tires got good and hot as the ride went on, causing it to eventually blow off.

    Probably could have re-seat the bead roadside but went with a tube in the interest of getting home (was 50 miles or so into a 65 mile route, and almost as far from home as it took me). It did not appear to have sustained any damage.

    The good news is, getting it set up tubeless again will give me an excuse to remove the tape so I can fish out the nipple that's been rattling around in my rim driving me crazy

    XG Pro TNT (700x32) holds up fine for me (w/ Stan's alpha 400) at 65 PSI.... with 30+ mph cornering on descents (which is scary)

    Yep 65-70 should be great. High speed cornering may be hindered but worth it if the tire stays on

    I'm curious to hear from anyone with experience converting Hed Ardennes rims to tubeless. I have a 2012 CL version of the wheelset and ran them in cross last year with tubes. I was hoping to convert them to tubeless using stan's tape and sealant and running either Specialized Captains 2bliss or Michelin Mud 2's. I'd like to hear from anyone with experience using these rims and/or tires tubeless. Thanks

    Anyone had an issue with folding racing ralphs and the bead tearing off at 60psi. I got the tyre replaced but it was a long walk home. Now running the the replacement tyre and the other racing ralph with no issues.

    Took these off to fit new rotors and thought I would post them up here as ive been following this thread.

    Lightbicycle XC carbon rims (21mm internal dia), hope hubs and DT revo spokes. 1560g wheelset. Set up tubeless with 3M 8898 strapping tape, stans and enve tubeless valves... I will be changing these out for regular tubeless valves when I need to refresh the stans as they were too long, hence the blue alu spacer.

    Anyone run a specialized carbon Roval 29er wheel with a cross tire yet? I'm thinking of pulling it off my mountain bike and setting it up with a Terra Pro 33. It has a 45psi max. I'm a little worried about damaging the carbon sidewall if I do hit rocks or roots too hard.
    Will no bead hook matter?
    Any Thoughts?

    I've been running the Captain CX 2BR on my front wheel (Hed Ardennes) set-up tubeless with 2 strips of Stan's tape. I've raced it at 35 psi on a really rough course with lots of roots with no issues. I weigh 175 pounds. It really grips well.

    Re: CX Tubeless setup thread

    I rode those rims on a rented road bike and couldn't stop thinking about how much cross tire they could put on the ground if set up tubeless. Glad to hear they work well. How was the setup? Guessing not too tough if you needed the strips

    You are running the Schwable RR in tubeless, and which size? I am wondering as I have worn out my Stan's Raven 700X35 and looking for something with a bit more grip.

    Why are you guys running such high pressures in cross tires? Kevlar bead tires whether they are tubeless ready or not are not safe at higher pressures. Road tubeless use a carbon bead that does not stretch and therefore stays on. I only weigh 142 so I can run lower psi and 40 is max for me but that's for commuting. Off road I'll drop to low 30's. There is no advantage to rock hard tires. As a gauge you want to have a little bulge when your on the bike. And not bottom out too often on rocky or roots trails.

    Today was my first ride tubeless. I am running Stan's 355 rim on the front wheel and a Stan's Iron Cross on the rear. The front wheel came from my mountain bike and was still in good shape but the rear needed a new rim and I had it rebuilt with the Iron Cross.

    I ordered a set of Vittoria XG Pro TNT tires when I got the rear wheel rebuilt. They were a pain to get on because of the tight beads and reminded me why I hate TNT tires. They aired up easily with the floor pump and I set them at 32psi front and 35 psi rear, fwi I weigh 165. Rode some smooth singletrack trail, road, gravel, and grass and things worked well. The ride was nice and when I rode over branches that were laying on the roads I barely felt them. I also tested the cornering ability out on grass and they seemed to do well. I may drop the air pressure a bit for racing especially if it is a smooth course.

    I also have a set of wheels built with Velocity A23. I tried to set them up tubeless with Schwalbe Racing Ralphs Evolution. I could not get the tires to seat with a floor pump. I took them to the shop and the got them to seat with the compressor but would go flat over night. They were extremely loose on the rims and I didn't trust them tubeless so switched back to tubes. I even tried them on the Stan's 355 rim and no luck getting it to seat. I don't trust a tire if I can't get it to seat with a floor pump or at worst going to a nearby gas station.

    Lots of my tires I could not get setup with out a compressor and they have been the most reliable. However that it MTB sizes 1.8 or larger.

    I seen the Vittoria XG Pro TNT also and was considering them and wondering if they offer more grip than the Stan's Raven 35mm?

    I am pretty much bald on my Raven's now so really need something to fit the frame.

    update -- ran Clement PDX on A23s with 2 layers gorilla tape and a 24" split tube. 0 problems with burps. Ran 40# in front and 50# in the back, obviously I would like to run a little lower in the back. 40# in the front was right at the limit for me when it came to squirm on this course. We had a fast paved section followed by a sharp paved corner that the front tire REALLY wanted to roll over on. I thought I burped on it but when I checked pressure when I got done, it was the same. Will definitely experiment with lower pressures in the back, I did not like the way the back tire seated so I ran a higher pressure as I did not have time to experiment. The pressures may seem high but I am 6' 6" and 240# so they are not unusual for me. The lowest I would run tubed is 45# as pinch flats become an issue for me there. This was a good test as there were 2 grassy off camber sections one that was basically switchbacks down the face of a hill.

    I set up my carbon roval control mtb wheels tubeless with the terra pro tires my bike came with for the race this weekend. I ran them with 38 psi front and back, it was a really fast/hard course with a high speed heavily rooted section. I burped the rear tire on the second lap but it held for the rest of the race (40 min). When I threw the pressure gauge on it afterwards it was sitting around 30psi. I thinks it's good and glued now!!

    Yes there the "2bliss" ready version. They work great in mud and loose sidehills, but don't role the best on hard-pact. Go figure

    Sorry, only seen your post. They are 33's, currently running Clement Las as tubeless.... nothing wrong with the ralphs, just wanted to try something with a flatter center profile.

    The Raven's might be a bit flatter, but also a bit less grip (rolls faster). Mine are 35mmX700. I may have to check the RR to run on my Bad Boy as there is not much space left, and I don't feel like going down to a 26er wheel.

    FWIW I have not burped my setup at all and I am always doing MTB on it. Usually in the 40psi range, but even less down to about 26psi. Lower psi though and tire roll comes in, and lots of rim bashing.

    AKRC78, I guess you burped the rear on the rooty section of the course? How much do you weigh. I've been running a Vittoria TNT size 32 set up tubeless on my rear wheel at 40-41 psi without any problems while riding some rooty single track. I weigh 175 pounds.

    Yeah, I hit a root pretty hard and felt it burp. But after that I went through the same section 7 more times with no problems. I set them up the night before with no riding on them prior to the race and I think they just needed to seat proper. I weight 170. They ran fine at 31psi just a little soft for the rear tire.

    Anyone tried setting up narrow rims tubeless? I've got a set of last year's Oval 327 CX wheels and the rims are 17mm wide. From what I've heard, the issue is that the narrow rims demand a higher pressure, but the fit on a non-tubeless rim isn't tight enough to ensure the bead won't blow out. Anyway, anyone tried this?

    They may work they may not. IMHO the most successful method is split tube. You may be better off just using latex tubes(admittedly I have never used them)

    Just set up some velocity A23's with Stan's yellow tape and rim strips with Clement tires. Seated up no problem, but took time for beads to seal with the help of sealant. I did not hear the beads snap into place. Usually heard that with my mtb wheels.

    Just out of curiosity, which Clement tires? I was thinking of trying either their LAX or X'Plor.

    Have X'Plor USH on 2 bikes, seated up well, with NoTubes took ages to seal, (Alpha and Mavic) in the end resorted to NoZisch to make the seal.

    Thought I would pass on my experience. I have had great success using Bontrager TLR rim strips mounted in Volocity A23's with numerous tires, both wire bead and folding. The strips fit perfectly and provide a generous "shelf" for the tire to seat on and the bead locks firmly into the strip. I have never had a burp or bead pop off with pressures between 25 to 40 psi(I'm 185). The TLR strips are much more durable than any tape. I'm currently building a set of HED Belgium's that will use the same system.

    wow sounds like a perfect solution. Are your A23s 1st generation(no ledge) or 2nd generation(have a tubeless "ledge")

    I have used both. My current setup is with the 2 generation.

    Anybody had their tires setup to higher than 60psi? I want to ride on the road to the local trails so I ride high 60's with my tires to get to the trail.

    EDIT: I do lower my pressure when I get to the trails.

    One of my coworkers had a Specialized Terr Pro 2Bliss blow off of his Alpha 400 at 75 psi. Straight line, on smooth asphalt.
    I gave him a hard time for running such high pressures. I just don't get it. He's at 65 now with good results.
    I don't think over 60 psi really helps much with rolling resistance.

    What tires are you running? and on what rims? Last year I ran 700 x 35 panaracer Tservs at 45 - 55 psi tubeless doing fast group rides and every day commuting and I was about 230 lbs. They were mounted on A23s. I cannot see you needing to go higher then that unless your rims are narrower or your tires are substantially narrower or your are heavier then me.

    I have Gigantex carbon rims with 18.5mm internal(24.5 external) width. I've been running Mud2, Jet, and Vittoria XG tires in various combination with tubes. Also, I'm running 60psi front 70psi rear on the road, down to 30F 35R on the trails.

    Anyone try the Rocket Ron's going tubeless ?
    From my understanding neither the Rocket Ron or Racing Ralph are actually TLR?
    We are debating these at my bike shop as my next tires on crest 29er rims. I can't get much larger than a 35/1.3 on this Bad Boy I have and from what we could tell only TLR is in 2.1 or larger?

    Hutchinson was also an option but apparently they do not like the Crest Rims.

    I mounted some Hutcinson Toro's on I9 Ultralight CX wheels yesterday using a basic floor pump. Super easy.

    My Giant CX bike came with tubeless ready rims (made by DT Swiss for Giant) and tubeless ready tires (Shwalbe for giant, 35mm).

    They are great. No issues so far with 4 races this year and lots of practices in thorn infested areas. Thorns no problem as long as the Stans is topped off.

    Too bad the whole setup is all proprietary to Giant. I think it's worth considering a Giant bike just to have this setup.

    As an update, I've run both MXP and PDX setup tubeless on a stans crest (front) and stans 355 (rear) with good luck. Part of this may be due to the wide rims? I started out the season with MXP front/rear but have changed to PDX front (for more bite), MXP rear. I'm ~180 pounds and run 36-38psi front, 40-42psi rear, at these pressures I've avoided burp issues and could probably go slightly lower.

    Changed my tubeless setup last week. Was running Vittoria XG pro TNT on stan's rims(iron cross rear and 355 front). I had no problems using them for the Iron Cross race and doing two traditional CX race. I just didn't like the feel/performance of the Vittoria's.

    I decided to try the Schwalbe Racing Ralphs again. I ordered a roll of 8988 tape and went to town. I used 5 layers of tape on both rims and put the RR on the rims. The fit was tighter than before and I was able to use a floor pump to inflate and get them to seat. Both tires snapped on with a reassuring pop.

    They lost most air sitting during the week but held air for the first ride that I did on them. The next day I had a race and ran them at 30 psi front and 34 rear. I think I was a little soft in the front and may have folded over the front tire in a corner which caused me to crash. The great thing was that there were no burps during the race and since then the tires have not lost any air.

    I'm going to increase the front pressure up to 32 and leave the rear as is.

    Would a Flow EX be too wide for a Panaracer Cinder X 35?

    I would use Crests, but my wife wants to ride in the next race...

    I have been using Stans Crest rims with yellow tape and Vittoria XG TNT tires this year with great success. Ran pressures sub 20 psi in a muddy race a few weeks ago.

    So far +1 on alpha rims w/ mud 2's (practice plus 1 race - a W). I had to mount up one bead first with tube though. 28f 30r 150lb rider.

    you should be able to order just the wheelset through a giant dealer. my teammate had to buy a new one after he ran over his front wheel.

    I am trying to run some tubeless singlespeed wheels. Having a hard time finding a good pair to work with though. anyone have any experience with ss tubeless setups?
    also I am interested in doing it as reasonably as possible. it seems the beginning posts are from a few years ago. How has tubeless improved over the years?

    The rim/tire combination is important. My post is above.

    What rim/tire do you have or plan on using?

    I do not run TLR nor any of my teammates (not schwalbe though) and we do not have any problems tubeless. See this article Going Tubeless for Cyclocross – Avoiding the Burp, Choosing the Best Tires, and a DIY System (Updated, Part III) | Cyclocross Magazine – Cyclocross News, Races, Bikes, Photos, Videos

    As far as Hutchinson not working with Crest rims, it will be more challenging to run any CX tire on the wider mtb rim.
