    Clyde and Flats...

    OK, so I keep having flats. 275lbs on a Trek HiFi Pro 29er. Bontrager Tires and Tubes with 45-50 psi with lots of thorn trees in the area. Stans, thorn proof tubes, strips inside the tire, kevlar tires, tubless w/Stans ???? What do you do ?? I am going crazy and broke investing in a tube per ride and either a patch job or long walk back......I have taken the tire off, turned it inside out, broke out the magnifiying glass and can find nothing inside or out in my tire. It's always a small puncture.....all my little friends say go tubeless with Stan's...

    tubeless and Stan's does seem to do pretty well with small punctures. My experience with thick tubes is... basically if something gets through your tire, it's getting through your tube no matter how thick the tube is. Those tire liners, I have seen one cause a flat (by wearing a hole in the tube), no idea how many it prevented. I've had pretty good luck with the Specialized armadillo tires and flats, not so much with the Continental protection line (so kevlar tires can be hit or miss).

    you don't say how wide your tires are. 45-50 seems like a lot of pressure, and that can make you more prone to punctures. Were you getting pinch flats at lower pressures? lowering 5-10 psi is the first thing I'd try.

    Tubeless is the way to go. I'm 6'5" and 220 and used to pinch flat, snake bite often here in
    the rocks of Colorado. Went tubeless 6 years ago with Stan's and I've never looked back.
    Very few tire issues now and I've used converted non-ust tires and ust tires with great results. I can't go the low pressures but about 35-38 psi works well without any squirm in the back. Tubeless works for clydes.

    Another vote for going tubeless. A friend as the Hi Fi Deluxe and I think his wheels came tubeless ready, so all you would need is the stans valve stems, and the stans sealant, no rim strips. I believe, ( But please confirm before you purchase).

    Im about 225-230 and have had zero issues running tubeless. I am running at about 25-30lbs of pressure and have no major issues. I have burped a few fronts but I think that was due to me messing with to low of pressure or bead not seated properly. No issues of late.

    Give it a try, it easy to do for a first timer, just watch stans videos on his website and you;ll be good to go.

    285lbs, hifi deluxe and I run tubeless around 35-40 psi and have only had one flat in the past 100 miles and thats because I let the pressure get too low in the tire. I would run tubeless with stans if I was you.

    Facing the same issue you are on the flats. Heading to the LBS for some of Stan's sealant, I should be tubeless tonight.

    Hey,

    I was in the same boat as you. 280's and running 45-50 psi on DT 470 rims and 2.0 The Captains tires. I would get a flat every other ride. I finally went with Stans and run them at 35psi and haven't looked back.
    If you don't want to get the Stans Flow wheels you can always try and run your current rims ghetto tubeless if they're not tubeless already.

    Good luck to ya!

    if you keep having flats make sure you don't have thorn or glass in the tire run your hand gently inside to see.Also look to make sure your spokes are not sticking trough the tape.

    I use to have flats all the time, Untill I installed new rim tape. The old tape looked fine and there was no spokes sticking though. Maybe a hole in the rim tape that you can't see.

    I've flatted 6 times in the last 2 weeks. Sounds like I need to look into the Tubeless option as well. I''m so frustrated right now I walked 6 miles to get back. However the coolest thing happened to me while I was walking. A smoking hot girl pulled up next to me to give me a ride. I thought it was like a penthouse forum story! Then my buddy who went back to the car pulled up. Drat!

    Try a new tire - a few years back I had a similar problem. I never did figure out why, but once I put a new tire on, everything was better.

    I tried the ghetto tubeless yesterday and it just did not work well. So I have Stan's kit for my rims coming, so I should be tubeless by the weekend.

    Have fun fixing a tubeless flat out on the trails.

    I'd suggest upgrading tires and tubes. Used to get pinch flats all the time, but using a set of 2.3" DH tires has stopped the problem. You can run low PSI without any issue. Specialized Clutch SX is my recommendation.

    Plus, the extra rotating weight gets you better exercise.

    Its not hard to fix a tubeless flat, you carry a tube with you and put it in when you get a flat, really the same thing if you have a tube setup.

    I'm 275 on a HiFi and I only ever run 35 psi with tubes with no flats. Here in Georgia we
    don't have the thorn problem that the drier regions do but we have plenty of pointy rocks
    and roots. I run WTB Wolverine tires and cheap REI tubes. At our size it does take a little
    finesse to clear things without bashing. Keep us informed on your progress.

    PS - my problem is freehub bodies. I've destroyed five of those now.

    When I lived in Arizona goats head thorns were a constant annoyance. While not a perfect solution I went to slime in the tires and the problem went away.

    I haven't done the tubeless thing yet, since I'm old and set in my ways. I will tell you that Mr. Tuffys in your tires will stop most of the thorns, except the really persistent ones that find their way into a sidewall.

    These 2 posts make the most amount of sense to me. I had 3 flats in a week once, it turned out that I had a spoke sticking through the rim tape.

    Since then, I really check my wheel every time I fix a flat or swap a tire. I've found a few small burrs that I polished, found another spoke issue that I had repaired and found a piece of wire inside the tire once.

    I used Stan's setup on my bike last week and it saved my butt this weekend. My wife's bike is going to be done this week. So far I am a happy customer.

    You guys are running tubeless at 280 lbs. You are brave souls. At your weight , all it takes is for the tire to hit something edgy just right, and the tire will separate from the rim. I'm 275, and run the rear tubeless, but the consequences are not the same. I wouldn't trust the front without a tube. Just MO.

    Gettting stronger tires is the best solution for pinch flats, if you also go tubeless, even better. Since I use GEAX Saguaro TNT I haven´t had a pinch flat, and that is 6 months ago!

    Also struggled with the fear of a front tire burp or blow-off.. Then with tubes, I had the front tire wash out, break the bead seal, went down, and figured hell- no tubeless isn't for me. [Caused by a thorn that dropped the psi.] Then I moved to an area full of brambles and starting flatting non-stop. Too many late night hike a bikes, and one walk along a busy road with bike in tow changed my mind.

    So, this past winter after cruising this forum, I decided to go tubeless with a set of Flows, using regular tires, yellow tape, and valves. No flats yet this year, get a better feel for the trail, and so far it works great. Don't believe that us big guys can ride the uber low PSI that some people talk about here, and am run about 5 PSI less than with tubes. Also set up my WTB LD's using the yellow tape, and valves salvaged from old tubes, and so far no flats.

    I thought I'd resurrect this thread to get some updates and ask a couple questions.

    Any more updates? Everyone still happy being tubeless?

    Also, could you notice an actual reduction in rolling resistance?

    My trails are pretty clean and i haven't had too many pinch flats running 32 front/34 rear, but I'm using Slime and its a 29er. I did some reading and Slime makes the tire about 2x normal weight and I do see green seepage (snakebite) when I pull the tire.

    BTW, I'm 230 lbs on the way down...

    I just realized that I'm likely got get a bunch of folks saying that I don't need to worry about the extra weigh on the bike... I'm not worried about it... just wondering if you noticed a performance difference in respect to the bike handling, etc.

    I am a huge fan of tubeless.
    Last ride I went on with tubes was only a short one, I took out 4 tubes in a couple of hours while being careful (that is a great thing about tubeless, you do not have to be carefull).

    Tubeless gives significantly more traction, lower rolling resistance, greatly increased reliability.
    The only downside is that the tyres get more bouncy, not everyone is perceptive enough to notice this.
    Then again some people are not perceptive to notice the pros either =-)

    I do not like the current methods of tubless at the moment, so 'invented' my own.

    Buy a ultralight inner tube that has a lockring. I use the continental tubes.
    If on 29" use a 24" tube, 26->20"

    This is your rim strip, mount it, then cut it down the middle an flop the sides over the rim.
    using soapy water, get that chalk off the strip. Let it dry.

    Mount the tyre and using a light contact adhesive (by light I mean runny/watery not weak, bostik is my current fave) glue the bead of the tyre to the rim strip. With contact adhesive let it dry before putting both sides together. so to clarify.

    contact adhesive layer on left bead and left of strip. Let it FULLY dry, then push the two sides together HARD. then glue on right rim strip and let it dry. if you are neat you can let it dry on tyre too, but I normally have rim strip dry and tyre wet on this side (too easy for the glue on the tyre to stick to the wrong side. Inflate your tyre.

    You will be amazed to see a tubeless tyre inflate with a hand pump, no sealant, no soap, no water.

    I can mount a 2.5" 29er tyre first time every time with a hand pump.

    This is basically mixing the perks of a tubular tyre and a tubeless.


    If you are careful you can remove that tyre rim strip and all and remount it later letting you swap tyres.

    The other major clyde friendly perk is you cannot burp a tubular tubeless tyre.


    Sorry for the unclear explanation, but although English is my native language, I can't be bothered to make sure it is 100% clear. So any questions, ask me. If I forget to check here, pm me!
    Why would I care about 150g of bike weight, I just ate 400g of cookies while reading this?

    I have been running tubeless for a year with ZERO flats. I will never go back to tubes and flats...35lbs up front and 38 rear, 275lbs and it works for me....

    I went tubeless in March. Specialized "2bliss" ready tires w/ stock Roval rims, also tubeless ready. Easy conversion, just put in the valve stems and some Stans. The beads seated just fine with my floor pump, didn't even need to get out the compressor.

    I can't say it has been mind-blowing and I don't have a dramatic analysis to offer (although I'm not really prone to hyperbole -- I just ride my bike!). It does feel a little better, the lower pressures seem to give a bit more compliance, although at 240#, I still run at 30# front, 38# rear to avoid dinging the rims.

    No flats so far, so that is good. I did burp the front slightly on Porcupine Rim a couple weeks back, picking my way down a very steep rocky section where I stalled on a square edge, putting my full weight on the front and ending with a 3/4 endo-roll. Don't know if it burped because of the weight and twisting as I went over the bars, or if I went over the bars and twisted because of the burp. At any rate, it sealed right back up and I was able to put a few more psi back in the tire and finish the ride without incident.

    Overall, a decent upgrade IMO. I will be even more impressed if I don't get any puncture flats all summer -- we'll see!

    Thought I'd chime in here because I'm having some minor problems running tubeless on my 26" rims. 330ish here and for a year I've been running both my 29" Stan's Flows and my 26" Mavic 823's tubeless and both have Speshy Armadillo Purg's 2.4 front and 2.2 Captains rear (32psi/38psi). My Stan's wheels never burp at all. Great rims. But today my Mavic 823's burped a few times over rougher stuff and the last ride I had major burping on the rear and then completely blew the bead on the front (my first "flat"). Thankfully enough Stan's sealant in it to get it to re-seat the bead on the trail with itty bitty hand pump. Wondering if I need a bigger rear tire, like 2.3-2.4? I find the Captain wallows a bit much on the 26er. The burping could just be the inevitable result of riding harder these days?

    Actually found some old threads on here about how the Mavic 823's just seem to burp a lot. Guess I'll have to live with it, or maybe just try other tires.

    I had a couple pinch flats on my 26 2.10 small blocks.. and i'm 6'1" 325lbs. I have had great luck with Bontrager tubes and found my solution to be this: Use a slightly larger tube. I run 2.2 - 2.5 tubes instead of the slightly smaller ones, and even at 50psi no more flats. Even on some tough roots and rough terrain... haven't lost a front tube in almost 100 miles (knock on wood)..

    I'm not super experienced, but was a cheap solution for me!
