    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.

    Just stepping in to say tubeless CX sucks. After 7 years of trying all the options i'm done. Not reliable for racing. Hello tubulars i'm ready for you and all your glue.

    Have you tried tubeless rims with tubeless ready CX tires? If you haven't then no wonder you're giving up.

    I have ridden this setup 3 times on trails. About 30-35 psi. No burping issues. However, I hit a rock and put a small hole in the rear tire. Stan's would not seal it, it was shooting out of the hole. I used a can of Caffè Latex and it slowly sealed. I had to ride gently home on a squishy tire. It seems to have sealed now, but it would not have been sufficient for a longer ride home.

    Just another data point....

    Clement MXP 33 (measure 35mm) 30 tpi on Some Alex rim (whatever is stock on Kona Jake the Snake) with a Stan's cyclocross rim strip, no problem. Some pinholes in the sidewall, but no excessive leakage. Rode quite a bit on it.

    Clement USH 35mm (that measure 33mm) 120 tpi on the same Alex rim and Stan's cyclocross rim strip. One tire has sealed up relatively well with one scoop of stan's. The other tire looks like a bulldog has slobbered all over it. Leaks pretty bad from just above the bead. It has 1 1/2 scoops of stan's and a teaspoon of latex mold builder. Haven't rode but a few miles on these.

    Edit, the problem tire finally sealed up.

    Edit #2.....I've gone back to tubes after a mystery flat with tubeless (and it was the tire that sealed up fairly easily, not the problem tire). I cannot recommend Clement tires for tubeless.

    I would try adding latex mold builder to Stans, like Manning mentioned above. I had same thing happen to me with a bonty 29-0...unfortunately had to figure out stans wouldn't seal during race

    Information below provided by mtbr member "dwt"

    "One part mold builder liquid latex ( buy on Amazon or art supply store), 2 +/- parts propylene glycol anti freeze. This is the pink/red colored non toxic stuff used for RV's, not the toxic green stuff used for cars, available at any auto
    Parts store

    This mix will seat and seal a tire, but not so good at plugging punctures. For that, add regular Slime auto tire sealant to the mix

    Now you're good to go"


    I got my mold builder from Hobby Lobby, you can also find it at some Michaels, be sure to look up their 40% off coupons before buying

    I've been running Michelin Mud 2's on Stans Ironcross wheels at 30 lbs. I had some problems initially getting them to hold air. I put a tube in to shape the tire, removed the tube (left one bead seated), put soapy water around rim and pumped. I got one tire to pump and had to take the other to the gas station. They worked well through cyclocross season; however, I've done 2 mtb races (with cx categories) with them and I got sidewall gashes (on the rear) and flatted in both races. The second one was very small (Stans didn't seal it).

    I love riding my cx bike in mtb races and wonder if cx tires just aren't made for this kind of abuse (e.g. rocky courses), or whether there are tires that will seat that have stronger sidewalls than the Mud 2's. Thoughts anyone?

    I blew out a Mud2 on the rear on my CX running tubeless on some old Mavic Reflex rims. No problem at 40psi but tried it at 35ish and lost a bead. I used the Stan's kit. I talked to Michelin and they of course do not recommend running the Mud2 tubeless. They wouldn't comment on whether they are releasing a tubeless compatible tire either. I talked to Stan's and they said the fit of the tire on the rim is crucial. I'm having the wheel rebuilt with a WTB Chriscross rim and will run a Kenda tubeless compatible tire. I will post up after I get the wheel back.
    I have come here to chew bubblegum and kick ass... and I'm all out of bubblegum.

    I had same issue mounting new muds, even using compressor.

    I ran Muds on alpha 340's last year at 27r/25f (?) @ 150lbs with no problems. My teamate (who I bought this wheelset from), could not get muds to stay on his Ironcross, even though they worked on alphas. His thought was that the Irons were a little wider. He has had no problems with specialized captains - not sure about sidewalls

    With all the options of tubeless compatible tires and tubeless rims why are people still going with unproven methods? I am not trying to be a jerk, I just do not see why people are risking a possible nasty crash with ghetto setups. I have run Kenda Slat Six SCT on both Alpha 340s and Crests with no issues. I have been down to 21 psi f/r on the Alphas without any burps (I weigh 145). My only hope is that some wider options, like 38-44c, that are tubeless compatible start coming out for those of us that do not care about UCI rules.

    You make it seem like there are a lot of tubeless ready cx tires. There aren't. The tread patterns that people want don't come tubeless ready.

    That's okay. Many non-TLR tires will work tubeless just fine, with the right rims.

    Kenda has six models with one size aleady SCT and a second size listed on their website, so 12 there.
    Hutchinson has 3
    WTB has 1
    Notubes has 2
    Specialized has 4
    Vittoria has 2
    Maxxis 1

    That is 25 possible choices. To me that is a lot.
    I am sure there are tires I am missing too.

    Keep in mind, how many mtb racers actually DO NOT run TR's due to weight, But i could see it on CX wheels, due to set up being more challenging

    Clement X'Plor MSO 40mm 120tpi working great on Shimano WH-7850 front wheel

    I'm jumping back in with my latest (successful) setup: I scored a near new Shimano Dura Ace WH-7850 front wheel recently (scandium rim, tubeless compatible, no spoke holes, etc) and thought I'd try to set up my Clement X'Plor MSO 40mm 120tpi tire on it for the upcoming Lost & Found race happening near Lake Davis, CA on May 31st.

    From my previous posts/experience, this tire did not like my Stan's 340 rims at all, blowing off the rim around 45 psi. This time I took the tire to 50 psi upon install (no problems), then backed the pressure off to 45psi, & went out for a 4+ hour mixed dirt/single track shakedown ride in Marin this Sunday. ALL GOOD, no burping, no nothing, felt rock solid the whole ride. I used Caffe Latex b/c I hear that's more friendly to the scandium rims. Now I need to track down a matching rear wheel.

    Bike set up is a 2011 Kona Major Jake w/ TRP CX9 brakes, FYI. The 40mm Clements fit front & rear w/ room to spare.

    I am curious why you prefer to ride such high pressures (to me at least). What is your weight?

    I'm 170lb. 45 psi in a 40mm wide tire when I'm riding rocky/dry/rutted single track at speed doesn't feel high to me, but I'm erring on side of not trashing my fancy new front rim. By squeezing the tire, and that one ride I did, I definitely feel I could case the rim if I got sloppy going fast at 45 psi (hitting a water bar too hard, getting blown off line, etc). Also, the Clement sidewall notes rec'd 55-90 psi for this tire, so I thought I'd start at 45. I'm no expert on this whole "gravel" thing, but 45 felt just about right. Now if I was riding some grassy/muddy euro type cross course on the level, that'd be a whole different story, with a whole different tire...

    I've tried the stans rimstrips, basically the same thing. Definitely helps with looser tires but I wouldn't consider it bomber.
    Yeah I only carry cans cause I'm a weight weenie.

    Thought I would comment on the combination I've been running for a couple of months now. I'm running Specialized Tracer Pro 2Bliss on Velocity A23 rims (the A23 Pro build wheelset to be precise) with Cafelatex as the sealant. I have to say that I am quite impressed. They hold air much better than the bike did with latex tubes. They are very compliant and fast.

    Mounting was very hard though. I have a 60gal compressor and that would not seat the tire. In the end I mounted them with a tube. That seated the bead into the rim. I left that for a couple of days. Then I deflated the tube and popped/opened only one side of the tire off the rim. I removed the tube and installed the valves. Then I flipped the tire over so that the open side was down so that gravity could help. Then a ful blast of air from the compressor. I had to push it to around 65-70 psi for the bead to then seat again. Then deflate and add sealant through the value.

    On my first ride I was running the wheels at around 30-35psi. I was alarmed at just how much squish there was in the tire and how it can "roll" on the rim. It freaked me out so much that now I tend to run 45psi. It's sill comfy and compliant but I feel it is just a little more secure and it protects my rims from the inevitable rocky trails I ride.

    Hi everyone. I'm new here. Roadie finally giving CX a try. Team races Trek bikes and the crocketts/boones comes with their Bontrager tubeless-ready wheel. I'm 139-145 lbs depending on the day and interested in CX tubeless. Hearing a lot of negatives but I'd like to see if anyone has experience w/ the Bonty TLR hoops raced with tubeless tires, and what set-ups have worked well for you.

    Thanks for your help.

    If you use tubeless specific rims and tires you should have a pretty fool-proof setup. I have both Stan's Alpha 400's and Crests. Currently running Kenda Slant Six SCT tires on the Crests and looking for a more mud specific tire for the second wheelset. I weigh 145 and had the Kenda's on the Alpha 400's last year as low as 21psi. No burping. No experience with the Bontrager rims though, sorry.

    CX Tubeless setup thread



    Hope Hoops utilising their Pro II Evo straight pull hubs, Stans Alpha 400 rims, Stan's Tubeless kit and Hutchinson Toro CX Tubeless Protect'Air Max tyres. Pretty happy with this setup.

    Thanks for your help.

    I have the Boone 5 disc and am in the process of setting up tubeless. I've been able to convert the stock CX3 to tubeless using Gorilla tape and Stans, but can burp by hand at 40 psi. I've switched to a pair of Vittoria XG TNT to see if these are better, and so far they are. I may need to add another wrap of tape as I can still get a really small wisp by hand. The shop I got the bike from didn't recommend the Bonty strips. I've heard that Bonty is coming out with a TLR ready CX tire that Comptom supposedly ran down to 17 PSI.

    Boone is a sweet ride!

    wait, what??? they DIDN'T recommend the Bontrager rim strips? My experience (albeit limited to one wheelset) with the Bontrager rim strips was absolutely glitch free and super simple to set up the tires. Everything I've ever read about the Bontrager system is that it is one of, if not, THE easiest system for problem-free tubeless setups.

    You need a new LBS.

    +1 Only downside is weight compared to other options (stans tape for example)

    That's funny. The Bontrager strips are a lightweight plastic, not lead. .

    And here I thought they were made out of rubber, at least I made you laugh.

    Bonty rim strips = 35g (1.23oz)
    Stans yellow tape = 5g (0.17oz)

    Some would agree this is the most imporrtant place to save weight - rotating mass at the outer diameter of wheel.

    Save 2oz of rotating mass AND spend less $, one of best weight savings per $, if you can get away with stans tape (I do and have no problems)

    Anyone try WTB TCS on Alpha 340 0r 400 rims? I have found only one mention of of someone using Crosswolf TCS tires on 400's, but everything else I find says the UST bead will be too tight.

    Digging that set up Ozzy. Any issues getting them set up tubless?
    If you ever see a turtle on a telephone pole, remember he had help getting there. Is there anything beer can't do?

    First attempt at cx tubeless, used Mavic Open Pros and Challenge Fangos

    What worked: A couple wraps of fiber (strand) tape, valves, sealant and a little glitter. Inflated right away with just a floor pump.

    What didn't: Thinking I had to set the bead, I jammed the rear up to 90psi before it exploded off the rim, spraying everything in the garage with glittery sealant and leaving me functionally deaf.

    Ultimately, they were much less work than tubulars. I set them at 40psi and raced a pretty dry course yesterday. They held up despite some nasty hits and rolls that had me wondering. I don't think I would trust them much below that pressure so we'll see as the season progresses.

    None at all, track pump set up first time. Got quite a few K's on them now with no issues.

    Running at 40psi defeats going tubeless as I can run clinchers with tubes at that pressure without flat issues. A reliable tubeless setup should get you into the mid 20psi range. I weigh 145lbs and can go down to about 21psi with Kenda Slant 6 SCT tires on Alpha 400 and Crest rims...and I only run yellow tape on the Alphas.

    Yes and no. The course I raced was fast and dry, I would have run 40 in my tubulars as well. But, Open Pro's aren't designed to be tubeless rims, so I wouldn't really consider them reliable to begin with. Like you, I have Crest rims with yellow tape on my mtb and wouldn't hesitate to run lower pressures on them because that's what they're made for. I'll just have to experiment with lower pressures until I know exactly how low I can get, but until then I'll sacrifice some psi for reliability in a race.

    CX Tubeless setup thread

    Sorry must comment - @145# I agree you should be able to get to low 20s - but that is entirely based on rider weight and tire size - I can't run a tubed cross tire at 40 without pinch flatting but I can run tubeless there so it is an advantage.

    If you look at sizzler's setup, looks like burping would be an issue when the pressure is in the low 20 psi...

    Maybe a Stan's rimstrip may help him to reduce the pressure

    That may be so, but you shouldn't run them that high, unless you just want higher rolling resistance, less comfort, and less grip. It's your call, ultimately.

    Won the race, so it seems to have been the correct choice.

    Might have been an okay choice, under the circumstances. Doesn't mean it was the best choice. The science on rolling resistance and traction, re: inflation, is pretty compelling.

    Congrats on your win, btw

    Thanks, do you happen to know any good articles or info about psi as it relates to rolling resistance, traction, etc? I'm interested to hear more. I've experimented a bit with low pressures in my tubs and personally felt it makes the bike handle less predictably and felt slower on hard surfaces, but clearly provides traction benefits in sloppy, wet conditions.

    You can start by searching L. Zinn's articles on Velonews. They often contain links to the actual research. I believe it was J. Powers who also wrote recently about getting over the concerns about squishy tires.

    Schwalbe had a research paper about lower pressures aimed at mtb setups. I have the pdf saved on my home desktop. They have the conclusion, so to speak, on their website:
    Rolling resistance - Schwalbe Professional Bike Tires

    I believe there are limits, obviously, as a flat tire is not the fastest and eventually going too low you lose support of the tire and it likes to get squirmy under cornering loads. Going from a good grass pressure onto paved corners can be scary as **** sometimes. Had this happen to me in a training ride last night with a new set of tires that like higher pressure (mid to high 30's) whereas my old setup loved the 30 psi range (I'm 220 lbs for reference).

    I setup the Crest 29 wheels with Hope Pro 2 EVO Hubs from my MTB on my Cross Bike with a set of Michelin Mud 2 tires last night to try in our first cross race of the season this Sunday. With the Hope hubs it was a very easy to switch the hubs from 15mm and 142x12 to QR 9mm.
