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

    I think the crest is only 24mm and I used to run 23mm road tires on in the city.
    I ran none TLR on MTB with out issues, but CX sizes are sort of a grey area so hence why I asked

    The reason Hutchinsons don't work on crests is due to the larger diameter of the rim, not the width. The carbon beads on the Hutchison's don't like to stretch.

    I ride CX tires on crests tubeless, as do others I know. All with great luck. None with Hutchinsons, most with clements (pdx or mxp).

    What pressure's? Weight?

    Inner id of crest - 21mm , alpha - 17mm , iron crosz - 20mm. My teamate went from alpha to iron cross & could not keep his mud2's on rimz . I guess u just don't know sometimes. He could not get pdx's to seal @ bead on alpha's either....

    I'm running slightly higher pressures because I'm paranoid and larger than your average cx whippet, around 35f/40r. I found the key to getting the skinnier tires seated on the crest was to always seat one bead with a tube before trying to set them up tubeless. It takes an extra 2 minutes and makes the entire process MUCH easier.

    I've heard of others having troubles getting the clements to seal on the alphas. Have you tried seating one bead with a tube before setting them up tubeless?

    Do you think a 35c non tubeless tire (panaracer cinder x folding) will work on a Stans Flow EX?

    He could not get bead to seal due to grooves in bead - sealant kept leaking out.

    I had to use tubes to mount muds

    He ran 28f/30r w/topeak gauge w/muds on alphas @ 175

    Reason i mention topeak is becauze i bought one & it read 5lbs less then my pump gauge. I am down to 30f/32r w/topeak @ 150lbs

    You 'should' be able to make it work, but it will square out the profile of the tire. You just need to ensure the tire is wider than the rim.

    It depends on what iz acceptable tire pressure. U weight, etc. Keep in mind your rim is 25tmm. While alpha is 17 and crest 21

    Tried mounting the cinder x 35m on stans flow Did not work as soon as I got to 40 psi the tire blew off the rim. Didn't work on my WTB trail rim setup ghetto either.

    Checking back into thread w/ feedback on a few setups

    I'm checking back in with some of my recent setup experience, here goes:

    1. Clement X'PLOR MSO 40mm wide on 1st gen Stan's Alpha 340 rims, w/ just one layer of Stan's yellow tape: not good, blew off rim above 45 psi, and felt like it would burp below that. Did not want to spend the time fussing w/ extra tape, etc. I just want a tire that works out of the box w/ these 340 rims.

    2. Clement X'PLOR MSO 40mm wide on 1st gen Stan's Arch rim front, one layer of gorilla tape, Bonty 29er rim (not sure what flavor) rear with Stan's rubber strip: pretty bomber, raced 3 hard dry condition races around 40 psi, with no drama, I'd ride/race this blew off rim above 45 psi, and felt like it would burp below that. Not the lightest setup for cross racing, but moto. These tires hook up real good on dry/dusty corners.

    3. Vittoria Cross XG Pro TNT 32mm on 1st gen Stan's Alpha 340 rims, w/ just one layer of Stan's yellow tape; ridden one hard practice session at 40psi front, 42psi rear and I'm happy. Tire was quite hard to get on, but held air for 2+ days WITHOUT any sealant added. I'd never seen that before (I've never dabbled w/ any UST specific MTB tires though). I added 1 scoop of Stan's to each tire and I'm gonna race these wheels over the next few weekends at some NorCal CX races.

    Conclusion so far: I really just wanted a plug & play tire for these 1st gen Alpha 340 rims & so far I'm happy w/ these Vittoria Cross XG Pro TNT tires (and they were on sale at Nasbar for $30 recently, which is way cheaper than good tubulars).

    What is your weight that you are running 40psi +?

    We've had a lot of success with the Vittoria TNT set up on tubeless specific road rims. For tubeless road/cross it seems that the fit of the tire needs to be a little tighter than your standard clincher set up.
    i.e. - Vittoria TNT tires have a slightly smaller diameter than standard clinchers and/or, Stan's Iron Cross rims have a slightly larger diameter than normal 700c rims so that you can run non tubeless tires tubelessly.

    I haven't tried to set up my Kenda Kommando 35mm tires tubeless yet, but I think it is noteworthy that the 35mm Kommando is dwarfed by the much more voluminous "33mm" Clement MXP. I want big and cushy and would not waste your money on the undersized Kommando. Also saw the Giant-propriety not for aftermarket 35mm tubeless Schwalbe Super Swans mounted tubeless on a friend's bike. They looked girthy and great and he said they worked great tubeless.

    I ran the CinderX 35c on Stans Crest-rear end at the CX race yesterday.

    I tried to run it at 35 psi, which felt really great on the warm up. Somewhere around lap 2 or 3 I started feeling the tire bottom out-must of burped, was down to 20 psi at the end of the race, fortunately it was one huge sand trap so I don't think I did any damage to the rim.

    What PSI are you guys running???

    I weigh 195 and I'm riding a mountain bike.

    Just to list a success so far. Stans Ravens CX on Iron Cross @ 32F 35R I am 175 bare. Two races on hard pack and several practices on same. I've mounted Mud 2s on these rims for a single practice session - was fine including one unseen trench where I thought I'd broken the fork.

    If/when the mud comes here to Norcal I'll try the Mud 2s again. Was trying to get Captain 2bliss - but they don't make the CX version anymore.

    A general question about running non tubeless tires tubeless. How are they at high speed descents? I'm a bit leery of hitting 40+ mph on a tire not designed to be run tubeless. Anyone have experience using a non tubeless tire for a gravel grinder or fire road riding in the mountains? Any thoughts are appreciated.

    I've been running non-tubeless tires on some Stans rims for a bit over a year now on my cross bike. I've hit 35-40 quite a few times on pavement and no issues. I think the first few rides after converting (had run the tires w/ tubes before) I was a little tentative with higher speeds, hard cornering, etc. Once I realized the tires weren't going to blow out or fall off the rim, I don't even think about them now. I did see my top speeds on one short steep descent actually rose about 1-2 MPH with the same tires tubeless vs. tubed. And I am running about 5psi less w/o tubes than I was with tubes. The tires were a pretty tight fit on the rims, I didn't have to use any extra layers of tape over what came on the rims.

    Re: CX Tubeless setup thread

    I had a non tubeless Conti 35 tear off my front rim once (stans alpha) coming through a tight turn on pavement. Luckily I was moving pretty slowly or things would've gone horribly wrong. If I do run a non tubeless tire without tubes again I will probably keep to the smaller side and look for the beefiest/tightest bead I can find.

    Think this would be less of a concern on gravel because there is less grip to tear the tire off with.
    Yeah I only carry cans cause I'm a weight weenie.

    Does not surprise me, I've never succeeded to get Conti on, either with Alpha400 or Ksyrium.

    Use tubeless ready tires guys! It's the safe and reliable option. There are more and more options out there now from Specialized's 2BR CX tire range, Vittoria's TNT CX tires, and Kenda's SCT CX tire range to name just a few. I wouldn't waste my time or money trying to mount CX tires that aren't tubeless ready.

    Crest with Conti Cyclocross. Works great. Weeped at first, but held fine.

    las, mxp, pdx sealed up on alphas for me with zero issues, they did burp around very hard off camber corners though. I put a mxp on a iron cross and couldnt even get it to burp with my hands at 20 psi.

    Easton XC One wheels with Specialized Trigger Pro 2bliss tires. Couldn't get them to seal for 2 days. I rode them for a 30min. ride on the road at 40psi, burped on big bumps.

    I think UST rims are not great for tubeless unless you have UST tires.

    I've successfully converted Alex SUB rims(Standard 30mm rim with 17.5mm ID) tubeless with Kenda Kwicker 32c tires.

    Took about 20 minutes to seal all the previous flat holes and bead areas to seal. I took the bike out for a 20km ride and they are holding air.

    I pumped them up to 70psi to make sure they don't burp on my commute and went back down to 50~60psi.

    EDIT: I've been riding in packed snow trails with 30 psi front, 35psi rear. No trouble so far.

    After about 3 months of running my Surly Knard 700x41 on an Ultegra tubless front wheel I finally got it to burp. I had no problems at 35-40psi. Then I forgot to inflate it before my ride and had about 30psi. While traction and bump compliance was killer it burped after I got on the top side of a rut and dropped it back in onto a rock.

    After reading through this post, decided to take a chance and see how a set of Schwalbe Sammy Slick (700x35c) will work tubeless on Enve Twenty9 XC MTB wheels. Originally wanted to use American Classic valves, but found them to short for the Enve rim depth after a bit of trial and error (mostly error), I finally got things to work using Orange Seal sealant, valves, and 24mm tape. Ended up using 3 layers of the tape per wheel and a Challenge latex tube to get the bead to seat, but looks like the effort paid off after a 2-hour gravel/mixed surface ride with 40-psi to start, tires had only lost ~2-3 psi by the end. Although the tires are still holding air as of this morning, I have ordered a couple sets of the longer Enve tubeless valves which should be the final tweak but may try a set of the Specialized Trigger Pro 2Bliss but are not yet available on the Spec. site.

    I've been trying to set up Clement MSO 120tpi 40c's on Velocity A23 rims with 2 layers of Stan's tape & Stan's sealant. I'm having a hell of a time getting them to seal up around the bead. What's worse is that when I let all the air out of the front tire, the bead slips back off down into the rim. At 25-30psi I can squeeze the sidewalls & air will escape. I'm sure I wouldn't run less than 38lbs or so but this has me leaning towards tubing them. I've never had trouble setting up a tire tubeless like this -the previous worst was a 26" Kenda Excavator that finally sealed up after a couple of hours. I'm on day 2 with the MSO's...

    Any suggestions?

    As another point of reference. I recently setup a pair of lightly used ritchey speedmax pro 35c tires on stans crests with 2 layers of yellow tape. After seating one bead with a tube, I was able to air up both tires with a floor pump.

    I have another stans crest/355 wheelset where I only have one layer of yellow tape installed. This works perfectly for MTB tires, and also works with new/tight cx tires. However, I was having a slight problem getting cx tires that weren't brand new to setup tubeless. It seemed like the tire wasn't sitting very tight against the rim, so all the air pumped in (with a compressor or floor pump) would just escape around the beads and would never actually push the beads of the tire into the rim's bead seat. Due to this I made the decision to use two layers of tape on my newer crest wheelset. Having the extra layer of yellow tape seems to make sense on cx tires where the beads aren't quite as large/robust as on a mountain bike tire. This makes installing tires slightly more difficult, but ensures a tight seal once mounted. I'll likely be going to two layers of yellow tape on the crest/355 wheelset as well since I plan to primarily use it on my cx race bike.

    I've been running alpha 340 wheels with vittoria Xg TNT tyres for about a year and and it's been a great setup.

    Getting a new disc brake cx bike in a few weeks though and was thinking of running the SRAM roam 50 29er wheel set, 21mm ID and 25mm OD, anyone tried these yet?

    I've had relatively easy times with tubeless CX setup - I've had 35c Ravens, 34c XG Pros (non TNT), 32c XG Pros (TNT), and 35c Ritchey WCS Sheilds mounted on ENVE XC rims.

    The Ravens were the most difficult to get mounted and sealed, the TNT XGs the easiest (no surprises there!). Loving the Ritcheys now - nice big volume, plenty of traction (in dry to damp conditions), and still fast on the tarmac. They sealed up really easily for a non UST/Tubeless tyre too, which was a bonus.

    How have your Sammy Slick's been holding up tubeless?

    Vittoria XG TNT and Specialized 2bliss is the way to go if you want ease of installation and sealing tubeless. Been running both for a full season of CX racing and some single track riding with no issues. I'm now running them on American Classic 29er Tubeless disc wheel set. The 32 Vittoria measures 34 on this wheel set and the Captain CX 2bliss measures 36. The wider 29er wheel set let the tires expand nicely and they sealed right up immediately with no issues. Oh yeah...I weigh about 170 kitted up to ride.

    I successfully converted to tubeless over the weekend. I used the Stan's Cyclocross kit and Michelin Mud 2s on my old Mavic Reflex rims. I replaced the cloth rim tape with two layers of Stan's and then used the rim strips. My only complaint is the rim strips have 44mm valve stems. They are very long. I guess people use some deep rims nowadays. I used an air compressor and wouldn't have been able to do it without one. On one rim, I had to remove the valve core to get enough air in to seat the beads. The bubbles from the soapy water showed the air escaping the beads faster than it could go in with the valve core installed. Then I had to keep my finger over the valve stem while I flipped the wheel around to distribute the sealant. I inflated to 40psi and left them overnight. The next day they were still at 40. I'm hoping to ride this week between rain storms.
    I have come here to chew bubblegum and kick ass... and I'm all out of bubblegum.

    I want to try my Conti 42mm Cross Ride/ Speed Ride tires on my Velocity A23's for a gravel race this weekend. I already have two layers of Velocity tape on them and Velocity valves ready to go. anyone with experience with these tires or these rims, or both, as a tubeless combo?

    I actually had pretty awful luck with Vittoria XG TNT's. Not the performance of the tire - although I didn't think it felt quite as supple as Grifo Open Pro's - but the wear was absolutely terrible. I ended up replacing the rear after only two months of use, having worn clean through the center tread. Now, I ride that bike a LOT, but the Grifo it replaced at least took the better part of a year to wear through. The front (I replaced both at the same time) still looks ok, but the center tread is definitely showing its age. I've got a SB8 in the rear now. It didn't set up easily but it's been a blast since.

    Do you ride them on pavement a lot? That is the only area I've really seen problems with wear, but it was bad enough that I used it to justify buying an old road bike

    Did you use the grifos tubeless?
    Yeah I only carry cans cause I'm a weight weenie.

    Yes to both, but the wear on the Grifos was far less than on the Vittorias, like 10 months versus 3 with comparable use.

    Would def buy a commuter, but I have an mtb and right now s-1=2, unfortunately.

    Good to know - the Grifo is my favorite tire but I haven't tried setting it up tubeless. Don't think I can rock a blackwall tire on my new bike

    Hey Mack,

    I have a Langster single speed with Schwalbe Extremo ZX 700C x 23 tubeless tires mounted on A23 wheels. I used two wraps of Stan's tape inside the rims and things sealed up well, holding 80-110 psi. Rims are good.

    Can't say how fat tires, especially those not rated tubeless, would work. Be careful using high pressures with non-tubeless tires since the tire beads are not designed to hold in the rim without a tube and failure could be catastrophic.

    Totally agree - I nearly wore through a brand new rear tyre in the course of a three day/1,100km mixed terrain brevet this year...

    I just mounted a set of Clement MXPs on Mavic CXP 21 rims. 1 layer of Gorilla tape and Stan's rim strips. I had to take the valve cores out to get the tires to seat. 2 oz of Stans Fluid in each. They lost pressure overnight, but I aired them back up to about 30 psi and took a short ride on pavement and then some soggy grassy trails. I will take them out on some trails this weekend and see how they perform.

    In the interests of fairness, the XG TNT's have been stellar as far as seal and toughness of the sidewall are concerned (though getting them over the rim makes me dread ever having to change one all by my lonesome). My CX bike is often also my mountain bike, and I've put those tires through sharp, pointy hell without a peep. If Vittoria increased the hardness of the center tread, these tires would be better than the Grifo's.

    I'd be interested to see if this works.

    Same tires on Stan's Crests and had one blow up in my face and the other when I hit the first bump. Pretty disappointed because I thought Stan's rims would hold most anything. After all that money I only lost a few ounces and still have to run tubes.

    redwarrior- I admit defeat on my new MSO's. I tried all my tricks and can't get the bead to seat. I found "part 1" of the review for these tires on gravelgrindernews.com after I tried and tried to sea them, (I read part two first, and bought the tires). Part 1 said Clement does not recommend tubeless setup. But I've only been beaten by one other set of tires in 7 years of "anything can go tubeless". Lighter fluid and a match is all I have left to try. Maybe I need to put on 4 layers of Gorilla tape.
