    Successful 29er TUBELESS CONVERSION SETUPs ( 29’’)

    Coming from 26’’world with 3 bikes successfully running tubeless for past 4 years and ZERO flats. Nice history. I am using mostly Eclipse (DT Swiss) conversion kits but STAN’s works similarly.

    NOW after crossing to 29’’ world and my first 29er bike (I love it) and 26ers start collecting dust at home, I am frustrated, say at least a bit. No tubeless tires (except Crow now), tires too big for tubeless conversion and difficult to inflate even with strips.

    I’ve spent a lot of time toying with 2 sets of rims and tires:

    Rims) Amer. Classic MTB-350 29’’ and Bontrager Race Lite 29’’
    Tires) Bontrager 2.2 ACX 29’’ and Maxxis Ignitors 2.1

    and of course Stan’s strips and yellow tape.

    Sofar, any combination is failing and after many hours, no success, even with compressor at home and on the gas station.

    HERE IT IS:
    ****************
    CAN WE SHARE HERE WORKING combination of RIMS, TIRES, PREPARATION PROCEDURES (e.g. USING STANS STRIPs or leaving the orig. spoke strip intact).

    I am sure many of us struggled the same way and letting us know what was the secret of the success for you, can help the other.

    Let me and other please know your successful 29’’ tubeless conversion procedure/ setup.
    ************************************************** ************************************************** ***

    Many thanks Pete

    American Classics:
    Nano Raptors wire bead and Specialized Fast Tracks
    Rim set up:
    3m strapping tape
    Stans valve stem
    electric tape (the good stuff)
    Stans sealant

    Sanded in side of rim lightly
    cleaned with rubbing alcohol
    strapping tape
    electric tape
    poke hole for valve stem
    place tube in tire pump up to 60 psi this set tape
    deflate remove tube
    add tubless stem
    add stans
    spray soapy water around wheel air up to until bead snaps
    do the shake and spin
    mine hold air for at least 5 days without losing more than 1-3 psi.
    The Nano's sealed up quick, but the Specialized needed a little help with some watered down degreaser around tire instead of soap.
    Used a compressor also.
    Team Mate has the Kevlar nanos and has no problems we are both 6'ft 170+ XC racers

    Try different rims. Mavic or Stans.

    I have inflated Maxis Ignitors on Mavic XC 717 disc rims with a floor pump, using rim strips.

    I've done...

    wire and kevlar bead notos, wire bead motoraptor and exiwolf, and now the crow. The wire beads were the hardest to seal for me. The beads are super loose and (of course) not flexible. I find that using a paint brush and working the soap and water into the bead until achieving an almost shaving cream like consistency works best. I've done them hanging and on the floor. Actually worked best for me to leave the tire/wheel on the ground then lift it with the inflator while holding the tire above the stem - let's you sort of work the bead/rim connection a bit. I don't think I could ever seal one of the loose fitting wire bead tires with a floor pump.

    Rims are the key. I use Stan's rims at 225lbs and they work great with Ignitors, Nanos and Exis.

    Just the tape and sealant (no rim strip).

    Pure bliss

    I have run Stan's rims with yellow tape and olympic strips with folding Kenda Karmas and Specialized Fast Tracks. 30-35# no toubles at all.

    I also have run Cane Creek Carbon Zonos wheels with the Karmas using strapping tape, electric tape and 26" std rim strips. No problems.

    I mounted (all folding tires) Bontrager's, IRC Mythos, and Ignitors and the beads felt very loose and unsafe. I did not have the gonads to ride them. The Karmas and FastTracks fit tight on both sets of wheels.

    Velocity VXC rims with Stan's 26" rimstrips, Ignitor rear and wire bead Exi front.

    drilled out inner valve hole on both rims. mounted both tires with tubes first and let them sit for a week (probably didn't need to be that long, I was waiting on parts for the build). used soapy water, 2 scoops of fluid in each tire, and compressed air.

    sealed quickly and easily, held air well from the start. No problems after at least 20 hours of riding.

    Anyone have any luck with Salsa Delgados? I spent a while trying to get the tires to seat on the rim, but got no dice.

    What's the trick with the soap suds?

    Bonty Rims

    I have bonti rims with wire bead motoraptors, my multiple flats per ride are history. I'm not kidding, The Africa terrain I live in has thorns like nowhere else. I use my own sealant mix, similar to what is commonly used by mtbr members.
    I am using the split tube method (shraeder valve) with a velox strip underneath to creat a tight fit for the tire. Link here: http://www.geocities.com/etrexkb/no_flat.htm
    I like having a valve attached to my rim strip, and the rubber to rubber contact seems very air-tight, although I haven't tried very -low pressures (under 25psi.) The shraeder valve makes adding sealant a breeze.
    The only thing I don't like is that if the tire get's totally deflated for some reason (adding sealant), the seal can easily break and I have to re-air with a compressor. With the tire to rim method (ala stans) the sealant bonds the tire and rim so that the tire is almost glued on. Once you get a good seal, you can air up with a minipump when you go flat.
    Since 26" shraeder tubes are in abundance here, I am using that for my rim strip.

    Made my own rimstrips from some 24" tubes....I will spare you the details because while the worked REALLY well...they did not work as good as the Stan's I am now running.

    I now run delgados (non disc) with Exiwolf tires
    follow the directions pertaining to 29er delgados exactly on the stan's site (i.e. use 2 layers of velox strips to build up the center section, install strip after drilling the valve hole.

    This proceedure is well documented on the stans site. I think most people will have good results if they use the rim compatibilty chart that Stan has on his site, and follor the directions EXACTLY!

    I selaed them with a Park floor pump...aired up easily as stan claimed.

    down side....
    If I run 25 psi or lower, I can and will burp air pressure and eventually break the seal. I ride very hard, and dont shy from jumps and such. If i keep the pressure over 30psi I have no problems.

    When you push the beads inward you can hear air rushing out (burping). this takes a great deal of force.

    My next plan is to try the ZTR free ride rims. according to the stan they seal up much better and if you push the beads together air does not rush out. Can anyone running these rims confirm this? Does anyone test their seals as Stan shows in the videos?

    I was pretty skeptical too coming from 26in wheels last April.
    Stans Olympic Rims
    Kenda Karmas(standard tire)
    yellow rim tape(bought from Stans for 5 bucks)
    I have been "Stansing" Kendas for about 2 years now so I know a lot of little tricks. These mounted quite easily though don't inflate them past 35#s. It might stretch out the bead.
    Knock on wood but no problems yet. As a matter of fact I had to have the wheel trued for a race the other day and the took of my tire in order for it to fit on the trueing stand. Slapped the tire on and aired it right back up again. No problems.
    I am going to convert my Bontrager Race Rims next, though I will use the Stans Rubber Rim strip for those.

    Caution;  Merge;  Workers Ahead! One more point

    I started using the 26" wheeled UST system when it first came out.

    Used several tire combos (UST and non UST). Stan’s rims are by far better than any UST system I have used in the past.

    Several Successful Setups

    For all applications, I use StanStrips and DIY sealant (latex/slime/AF/2water)
    So far I have done -

    Matrix road rims with wire bead MotoRaptors - took patience to get the strips into these rims w/o buckling, but it worked (rim a bit too narrow)

    StanZTR rims with FastTrak, Ignitor, wire MotoRaptor (used)

    All of the new tires have gone together easily - the Moto I switched rims on was a bit of a problem.

    I always use an air tank to seat the bead. I apply soap/water with a squirt bottle set to "spray" and shoot it directly into the bead/rim gap all around. And if all else fails - give the wheel a spin (1 rev then stop) and then hit it with air quickly before the sealant can get very far. If you spin and wait, you will have sealant drooling all over the place. But done quickly, its a sure thing for seating. Learned this on 26ers.
    This isn't a "you're doing it wrong" topic.

    Delgado Cross, Schwalbe Big Apple 2.35", non-ZTR Stan's 29" strips, cork bar tape underneith.

    Older ZTR rims with Stan's 29" ZTR strips, Fast Traks and Karma's. Karma's require thicker goo solution when home mixing.

    stans ztr rims with the yellow tape. (he sent the rims with strips too, said they were optional, so I didn't use them)

    Kenda Karma's - zero issues.

    They tires are very tight on the rim. I have run low pressure nad snapped the tire off on angled rock more than a few times. Never burped air.

    I would like just a tad more grip in the front, but they just roll so fast, it's hard to change to something else.

    another option

    Posted this reply in another thread recently, but this seems like a good place too.

    I've had success with Maxxis rimstrips. $5 on their website. Plus Stan's sealant.

    On DT 7.1 with Maxxis Ignitors. Had to use the stock plastic rimstirp, plus two layers of strapping tape(with fibers). The Maxxis strip goes on top of that. About 1.5 scoops of Stans per tire. Able to inflate with floor pump when I pumped REALLY fast. Once bead is seated, no issues. I've used this setup for several races now... loses very little air in a week.

    On Bontrager Superstock wheels with wire bead EXIs. Stock rimstrip(cloth), plus one layer of strapping tape. About 1.5 scoops of Stans per tire. Again, took some initial FAST pumping to seat, but then no problems. A few rides on this setup so far.

    Maxxis strips come in different widths/depths for 26inch wheels. Since you're stretching them so much, I don't think the model number matters all that much, but I ordered according to my 29in wheel's depth/width.

    MC 29er stock rims & notubes?

    Has anyone successfully converted the stock Alex rims and EXI tires that come on a Monocog 29er? If so, which rimstrips did you use?

    Thanks!

    29er Stans 355 w/ Fastracks...

    have worked great for me with only the yellow tape (once the trails dried out ). Will need to find a different tire for Fall/Winter. Like how light the rims and tires were, wheelset is probably the same as average 26", but with all the advantages of the big wheels.
    that rug really tied the room together.

    DT RR 1.1 built up with 2-sided foam and sealed with strapping tape, Maxxis Ignitor, 2 scoops. Inflated with a compressor and took ~an hour of messing with it to get it to stop leaking and hold air. Had to add air after the first three rides (ridden by my 115lb wife). On the fourth ride the tire (front) blew off the rim on a descent. She bled and bruised but didn't break.

    Stans ZTR 355, yellow tape, Maxxis Ignitor, 2 scoops. Inflated with a floor pump, sealant did it's job in just a few minutes. About 3 minutes into the first ride, the tire blew off the rim. No injuries, but that was strike two.

    Stans ZTR 355, yellow tape, IRC Mythos R, 2 scoops. Inflated with a floor pump, sealant did it's job in just a few minutes. Rode it around the yard, around the block, up and down a few curbs, etc... to get it seated. No burps, no leaks. Tire blew off on the way to the trailhead. Strike three, and no more tubeless for the wife.

    I've used various combinations of 700c rims and 29" tires without tubes over the last 5 years. Mavic rims, Bontrager rims, Stans rims, Salsa rims, and Zipp rims. WTB, IRC, Kenda, and Maxxis tires. All using Stans strips and sealant. All have inflated and sealed, but all have also ultimately failed, some quicker than others. It's rare for any of them to last more than a few rides. The best, most durable, longest lasting setup was the Kris Holm Unicycle rim, Stans DH rim strip, and a WTB wire bead Exiwolf. The rears last a few rides at best before I punch holes through the tread (riding sharp rocks) or tear a sidewall. I had one front that lasted ~6 months, but typically they only last a few rides before the tire fails.

    DT RR 1.1 rims on a wheelset built by mikesee, Stans 26 inch rim strips, homemade sealant and Nanoraptor tires. 165 pound rider on a GF Rig racing hardpack conditions in Michigan.

    I have tried many 26 inch tubeless tire setups and expected to have some difficulty. Much to my suprise, tires inflated with small compressor on first attempt and held air overnight. No problems the next day during a 20 mile easy ride so I decided to use them at my next race, an 8 hour race. I had a brake issue during the race and switched to my 1FG for a lap. After that lap, I was a 29er converter.

    Tires held air during the entire race without issue. Mileage was around 100, 50% singletrack. Four days later, still at same pressure.

    It's been my experience that nearly every manufacturer will state not compatible with tubeless but we know better. Some of the items that Stans won't endorse have some back story such as the DTSwiss hubs. It doesn't mean they won't build up well. Stand just won't offer you much support if it fails.

    I am seeing several DTSwiss hubs built on the discontinued Olympic and the new ZTR hoops that have tied and soldered spokes to extend the virtual flange. The trick is finding someone that knows what they are doing with that type of build. I am real curious to see how some of the lighter tubeless setups work over time with riders over 160lbs. Mostly, I want to see how the hub bearings hold up.

    Good points. Other than the Bontrager Jones ACX (which broke a bead and blew off the rim after two days), I've had complete success with every 29er tire I've converted, including:
    • WTB: Wire beaded Nano and Moto Raptor and ExiWolf
    • Kenda Karma
    • IRC Mythos XC II
    • Bontrager Jones XR (the big ones - after my initial bad experience with the Jones ACX, I was hesitant to try the XR tubeless, until T. Brown told me he'd been doing it successfully for quite some time.)


    I've successfully mounted and ridden on each of these tires for at least a month at a time without issues. None have blown off the rim, despite bashing, jumping and beating them just as I would any tubed tires.

    My current setup is a Jones XR on the front and a Karma on the rear, both tubeless with my Mold Builder and windshield washer fluid-based "getto Stan's" solution sealing them up.

    I've done this successfully with Mavic A719 and Salsa Delgado X (non-disc-specific) rims, taped with one pass of strapping tape, two passes of electrical tape and a cut down 24-inch tube as the rim strip/valve. I've also used Stan's 26-inch rim strips stretched to fit the larger wheel with good success.

    I'm curious about what pressures you were running or why you think you had so many blow off episodes? I've stayed with wire bead tires due to fear of blow offs but obviously a lot of people are using folding beads with success.

    Also, are you saying that a Stan's set up makes a tire more susceptible to sidewall cuts?

    In the wife's tires I typically run 22-26psi. I run mine typically at 26-29psi. Never over 30psi in any of them.

    Any DIY tubeless setup makes a tire more susceptible to flats from sidewall cuts. If you cut or nick the sidewall, the sealant may or may not be able to seal it. If there's a tube in there, you'd have to cut the tire and the tube. With respect to sidewall cuts, my experience is that I rarely cut the tube, and (if running tubeless) the sealant is never able to fix it.

    I just discoverd this thread. I will add a few details to the set up I have been running.

    I am using:

    DT Swiss RR 1.1 Rims
    Maxxis Ignitors
    26" tubes for rim strips
    Stans NoTubes sealant.

    2 days ago I re-did the set up. The tube sort of bonds to the tire, creating the seal. It is easily pealed off without doing any damage to the tire. This time around I added 2 scoops, instead of 1.5 of the sealant.

    I have had some very good results using this DIY set up. The KTR was the acid test, and I had no problems at all over the 142 miles. Since then I have raced/ridden many miles with no problems. I am not a light weight either, sitting at 173lbs. Every few days I top off the tires as normal. I usually run ~35lbs of pressure. I have been told that running anything over 40lbs is not recommended for this set up.

    I will admit that I was skeptical about this set-up, but it has worked very very well.

    Stans 355 rims, yellow tape, maxxis ignitors, 1.5 scoops, ~20psi, 2 weeks, 50 miles, no issues. Had to air up with compressor.

    150lb rider, SIR9, pace29, i9 wheels.

    So far the setup is great, and can't wait to get it on more trails. Went through some small, sharp rock gardens already. Small burp once on a landing. Going to go up a few psi in air.

    Entire stans notubes related items, including 1.5 scoop of sealant was right at 100g total per wheel.

    Anyone successfully convert the new 29er DT swiss 340 rims? I have yet to try.

    Any DIY tubeless setup makes a tire more susceptible to flats from sidewall cuts. If you cut or nick the sidewall, the sealant may or may not be able to seal it. If there's a tube in there, you'd have to cut the tire and the tube. With respect to sidewall cuts, my experience is that I rarely cut the tube, and (if running tubeless) the sealant is never able to fix it.

    Not sure if your tire was blowing off because of too low psi, but I've pinch flatted UST tires when I accidentally ran them that low (mid 20s psi). I had had them at about 35 psi, but forgot to top up after the bike had been unused a week or so. yeah, and I thought I would be AVOIDING pinch flats going tubeless I actually never pinch flatted a tube, but wanted to use less pressure, so converted to tubeless. Can run it lower, but no TOO low

    Good job! Mavic 217, with Stans 26" 517 strips stretched on, Notos folding

    My limited experience:

    I inherited a pair of well ridden XTR/Mavic 217s (the rare 700c size) that were built up for a Willits 29er back in the late 90s here in Crested Butte. I've been running them on my purple Fisher Rig singlespeed for about 2 seasons now. To setup tubeless, I took off the old velox rim strip, cleaned them up, put a layer of Stans fiber/packing tape, then stretched on one of Stans 26" rim strips (the original narrowish one, designed for 517 rims). I'm running IRC Notos 2.1 folding tires with 1-2 scoops. Stans seems to dry out pretty quick up here in Crested Butte (maybe the dry air) so I check/refill every month or so. The Notos are about worn out, so I'll be putting on some 2.1 WTB Motoraptors real soon. I've got a brand new Delgado Disc, 36h, supercomp spokes, alloy nips, Hugi/Hayes 6 bolt hub FRONT WHEEL that Mike Curiak built me up (so I could set up a disc brake in the front) but after reading all the hassles with getting this rim to work with Stans (and the fact that Salsa strongly discourages it), I think I'm going to sell it. If anyone's interested in a bomber front wheel built by a great wheelbuilder, give me a shout. I just can't go back to tubes after having so much good luck with Stans (my 26" mtn bike is running strong with Stans too)

    Thanks,

    less weight, less flats

    stans kit with bonti rims -
    Only one sidewall tear (always carry a tube) in my second season of riding tubeless (3-4 rides a wk)
    Maybe two times a season I remove the valve stem and squirt in some more goop, pump up and keep on a gittin' it....

    Cush,

    Which tires and Bonti rims are you using for your tubeless setup?

    I have spent the better part of a day trying to figure out the optimal no-tubes tire for my Bonti Race Disc. Seems like a hopeless task trying to find a tire that has good reviews, decent weight and is suitable for a Stan's notubes conversion. Sort of a shame my Bonti Jones ACXs aren't recommended. They have good reviews and are very light (570g.)

    Forget reviews....Ignitors will work fine tubeless

    Hoy,

    if you talking about 29er than, I have the bonty race lite 29er. But have not converted them. But I am confident now that it would work. Good tires I am using tubeless on my 29er AM Classic set are Maxxiss Ignitors - no probs. and also Stans Crow. Both of them just with stans yellow tape. Had to use couple 12g CO2 cartridges with compressor together to seal them... but once sealed work as charm...
    I am confident now I could seal bontys without the problem too. The trick is really to use CO2 rather than compressor...... much bigger air blast.... read my post I am about to post now......

    The Trick is CO2 cartridge for sealing - forget compressor !!!

    Hi everyone,

    I have to say I now have been able to run 2 sets of tires on my 29er... that is 100 % success...... and the biggest trick after doing this for such a long time.... use CO2 cartridge. to be precise several and compressor with it. Untill recently I thought the compressor is the best thing to use. The reality is the unless you have something special- meaning a big thing with huge tank that can output big volume (the pressure is not that important), then compressor often is not enough for 29ers. The compressor at home and even the compressor on the gass station will not give such a air blast as cartridge. I have the 12g/16g CO2 inflator; have bought box of CO2 cartridges in Wallmart (cheapest about 60c/ 12g cartridge).
    So to seal AM Classic 29er set with only stan's yellow tape I have used sevelar cartridges(one or two failed to do the initial inflation) and the compressor.

    the blast from CO2 seems to be by far of larger volume than all compressors (including those at gas station). so I seal the tire to the rim and then quickly inflate more with compressor up to 60 psi. that guarantees me the tire will not deflate. then I quickly start shaking and sealing (OK... forgot to mention that before I start inflating I put inside 2 scoops of Stan's latex).

    And this whole process of using CO2 with compressor works....

    To give you better Idea - my compressor is in about $80 price range.

    I was glad to "waste" couple CO2s to finaly win the battle. I am now confident this process would allow me to seal almost any combination... beleive me the Ignitors were pretty loose on AM CL. rims and still sealed...

    Crows worked fine just with compressor...

    American Classic 350's and Kevlar Exiwolfs.

    I followed the directions. The combo works flawlessly for me.

    Thanks for the feedback. So, for running tubeless it's between the Maxxis Ignitor (705g. 29x2.1) and the WTB ExiWolf (825g. 29x2.3). I think they are both 60 tpi. I'm running 26" UST Ignitors on my C-dale Prophet. No complaints with those. Of the two, does anyone have a preference for use in mid-Atlantic woodlands? Does anyone know which of the two provides a tighter fit?

    hmm...CO2 inflator...

    Has anyone tried using a scuba tank for this. You can buy a tire inflator (schrader) for the LP hose on the 1st stage regulator which will inflate a tire very quickly. Its a big investment but for those divers out there with their own tanks and regulators it's an extra $10. Plenty of air in a solid uniterupted stream. The air nozzle attachments work wonders for blowing crap outa your components as well.

    I'm still researching this tubless thing but when I get it all figured out I'll give it a go and let everyone know how it works.

    You can use a scuba tank, my buddy takes his with him to far away races just in case something happens. Plus it is easy to use at home.

    Not sure why you'd need a scuba tank. When I converted my tires to Stan's NoTubes I used a floor pump and inflated the tires just like they had tubes. No problem at all. The trick was to use plenty of soapy water and keep the wheel vertical with the valve at 12.

    Another Successful Tubeless Conversion

    2006 Gary Fisher Paragon.
    Bonrager 29" Race wheels.
    WTB ExiWolf tires (folding).
    Stan's NoTubes 26" conversion kit.
    30 psi front. 35 psi rear.

    No problems encountered. No leaks. No burping. No flats. Used floor pump to inflate tires on first try. Watch the how-to video on notubes.com and follow Stan's instructions closely.

    Thanks everyone who recommended the WTB ExiWolf tires.

    Update 1/15/07. Notubes has been wonderful. I took my bike down to Panama which involved having to remove the tires in order to pack the bike. I was able to reinstall the tires with no problem at all. In fact, I just use a floor pump and pump at normal speed. The tires held up to some very rocky areas and big thorns.

    Will really want to see the results of this. I am running Mustangs with Stan's 26" strips but have a set of Race's (same rim I think) that I would like to try without the strips. Is his tape anything other than electrical tape or is it stiffer? I was thinking of going 1 strip of electrical tape with strapping tape over the top.
