Raydek Posted October 30, 2014 Posted October 30, 2014 Well remember me to wave to you when I pass you on the side of the road with a flat. Surely they can't be 100% guaranteed no flats??
Cejay Posted October 30, 2014 Posted October 30, 2014 I'm in the same boat, I don't see the benefit of tubeless.. It just seems like a mission... I am running as low as 1.8bar (26psi) with tubes in Conti Race Kings 29" x 2.2 and have had maybe one flat in a year.."So what did you do Son,nothing Dad I just smiled"
cadenceblur Posted October 30, 2014 Posted October 30, 2014 I reckon it's guys not doing it right, I"ve had tubeless for a year now, without a single issue, the guys I ride with as well. All the conversions have been done by LBS though, so you never know...
Wil6 Posted October 30, 2014 Posted October 30, 2014 Surely they can't be 100% guaranteed no flats??In 8000km I never had a flat in a race or training ride. Just make sure you always have enough sealant left before each ride and take a couple of plugs with you. Sometime you get a nail or something in your tyre and the plugs quickly seals the hole and you can ride again with no time lost at all

Raydek Posted October 30, 2014 Posted October 30, 2014 Would the longevity/quality of the conversion depend on the rims? Cause I don't believe I have the greatest rims out there, they are tubeless ready though... Kore XCD SL
Captain Fastbastard Mayhem Posted October 30, 2014 Posted October 30, 2014 It'd depend on the rims, tires and your installation.
Headshot Posted October 30, 2014 Posted October 30, 2014 Ya, there are many variables. Decent rims and tyres make the set up far easier. Some rims and tyres just don't work well. Rims may state that they are 26/650 /29 but in practice they are not all the same. Same with tyres - some fit a rim tightly, others not. A couple of good tubeless rules/tricks. 1. Try and buy tyres with proper thick sidewalls eg WTB ,Conti protection range, Maxxis LUST and Scwalbe snakeskin or super gravity. Some older designs had flimsy sidewalls and leak sealant leading to burping off and/ordinged rims if you don't notice in time. Specialized tyres pump up easily but have the leaky sidewall syndrome. 2. The main problem I have encountered with tyres not seating when fitting them yourself is when the bead of the tyre does not fit over the rim strip tightly enough when the tyre is flat. Air just leaks out and soap does not help. Even a tight to fit stiff tyre is sometimes loose over the rim strip. A solution which has helped me 100% of the time is to wrap 2-3 layers of normal insulation tape over the rim strip. The tape just needs to go over the center of the rim ie over the spoke area and not into the bead so on narrower rims you may need a narrower tape. The effect of this is to cause a seal between the rim strip and tyre beads that allows the tyre to inflate tubeless and lock into the rim bead groove.
Dirkitech Posted October 30, 2014 Author Posted October 30, 2014 i just had the reply below typed and before the image upload messed up the page and had to reload... sigh.I have no idea why you get pinches at high pressure. But add some babypowder to the inside of the tyre, it helps the tube move out the way when the tyre compresses. I run this on my trials bike and never get any pinch flats!!thanks for the suggestion- I'll definitely try it! At least, it may help me mount the stubborn mtb slick! Why would you not want to go with tubeless? It's just better in every way. Oops... forgot to mention something- see my reply below please.But the amount of times I have seen guys riding and suddenly one of their wheels just starts squirting out sealant is a lot more.. What happens then? Bomb it? Tube it? Is this a common problem or these guys just not doing it right?This scares me more than a puncture... if a tire tears/cuts during a race, you forfeit? Does the rim not damage easier without a tube for cushioning in case of a blowout or whatever? Anyways, I should have mentioned this- I have 1 set of wheels on which I use both my mtb tires and mtb slicks. I cannot afford to buy slime each time I swop out tires. Also, the whole tubeless thing sounds wholly more expensive that running a tube- is it not? Im attaching a picture of my rear wheel. It has conti rim tape to the rim but I doubt the pinch flats were ever from spokes sticking into the tube. PS: the tire in the attached picture is not the one that I get snakebites with. edit: picture got cropped very badly. trying to fix it
dillon Posted October 30, 2014 Posted October 30, 2014 i had a stick thicker than a pencil penetrate my tyre and the sidewall. (Schwalbe Hans Dampf), bombed the tyre and rode on 15kms to finish the ride. Only problem in 15,000 kms of riding. thoooobless is the way!
rouxtjie Posted October 30, 2014 Posted October 30, 2014 Guys I think the OP has made up his mind ito not running tubeless... To the OP, pinchflats...its part of territory when you have tjoobs. Deal with it

Besides thin smooth tyres where designed for road bikes, they just look weird and wrong on a mtb.And on that bombshell GO TUBELESS (once you go tubeless you'll never go back)

Riding in the cape with our thorns and a few pinch flats, I had my arm twisted into tubeless.Man what a great move. I havent had a flat in 9 months of tubeless riding, as opposed to having races cut short, walking off mountains cos i have a flat. My biggest problem about tubeless is getting ragged that I was against in the first place. About sealant pissing out. About 3 weeks ago I was riding at hoogekraal and in the first 500m of my ride i got the dreaded psssssssssss. Well sealant pissed out, air made noise. I stopped spun the wheel, kept on leaking so I thought my ride was over, turned around to go home. and the tyre sealed up!!!! went on to do my ride, didnt even have to pump up the tyre. The big trick is make sure there enough sealant. It works
Long Wheel Base Posted October 30, 2014 Posted October 30, 2014 Maybe you pinching the tube when you put it in? Iv seen plenty times(even to me) with a tyre that fits tight onto the rim when you change it and slide that last bit over onto the rim there is a little bit of tube stuck in the way and it pinches it with a small gat that leaks slowly.

Deal with itwhat does your post have to do with the tire pressures affecting pinch flats that i'm querying? please don't reply if you can't help or contribute meaningfully.
