Tube or tubeless?

y2keable

Just bought a new stumpjumper carbon FSR, chap in the shop asked me if I'd like it set up with tubed or tubeless tyres. How do I decide this? I've never had tubeless tyres before =/

Go tubeless would be my advice, cuts the risk of punctures due to pinch flats and thorns etc as the sealant fluid inside the tyre will seal these as they happen, you can run lower pressures too..........no brainer mate.

Tubeless, just learn how to do your own changes when the time comes....

Fair enough, thanks chaps.

Thought it may just depend on this and depend on that...

Where do you ride?
How many punctures do you pick up now?
Do you like to change tyres according to weather conditions or terrain?
All things to consider.

How much spare time do you have? Every time I go tubeless I end up burping a tyre which won't reseal on the trail, so I put a tube in to get home and then 6 months later it's still in there.

That's what's always put me off a tubeless set up, I know tubless devotees insist they are less hassle but I'm just not convinced.. If I suffered a lot of punctures I'd seriously consider it but I don't, and I don't run mega low pressures.

That is broadly where I'm at, I don't like lower pressures it just feels horrible (to me) and I get so few punctures to be neglible. So I've stuck with tubes. Plus I know how tubes work, and for me they work fine, no problems.

Must be badly set up. In three years I have never burped a tyre and the only punctures I have had have torn the tyre so ruined it anyway. It takes ten minutes a wheel to set up using a CO2 inflator to seat the tyre.

Tubeless it is the only way!

Lower rolling resistance, less weight, more grip and fewer punctures - what's not to like? If you're burping tyres, then more likely its inappropriate riding for the conditions - the kind of impact that would cause a snakebite anyway.

Perhaps your tyre pressure is too low.

It's not so much how long it takes that's the problem. It's more about remembering to fix it in between rides. My riding is generally after work so I'm in a hurry to check tyre pressure and put kit on then I get home, put the bike away and forget about it until next ride.

What are you needing to fix between rides? I've been tubeless for a year and never done anything between rides. I've never had a puncture and never needed to pump them other than when I want to change pressure for road or trail. Only thing I've had to do is change the valve on the rear once because it sprung a leak. Other than that I don't have to do anything.

As for burping tyres I think that is dependant on what you ride. Light XC tyres are going to burp more easily than something with a stiffer side wall. The guys I ride with are very much XC so I tend to keep tyres as light as possible.

Been tubeless for nearly 15 years and never burped a tyre. UST Mavic, converted Mavic, Stans, Roval and Light Bicycle rims. Schwalbe, Bontrager, Spesh, Continental, Hutchinson, Michelin, Maxxis and Panaracer tyres, some tubeless, some not. Just about every lightweight tyre going. User error I say.

My Giant branded Pxc-2 rims were terrible running tubeless with a Swalbe Racing Ralph and Nobby nic which Were done by a bike shop . I found out later the tyres were really baggy on the rims. Basically I ended up ahving to run too high a pressure to stop burping.

After faffin about a good few times I gave up and stuck tubes in again. A trip to my LBS and to a Giant specialist shop both confirmed it was known they were a crap combination. Basically the rim came up slightly small, the tyre slightly big and the sidewalls were a touch too thin.

I have just bought a Spec Purgatory and whilst not as good a fit as it is on my other MTB with mavic rims its far better.

Perhaps your tyre pressure is too low.[/quote]
But low pressure is the point of going tubeless. I run 25psi on the front with a tube without problems. If I go tubeless anything below that results in burping. It may be a problem with my rim's profile.[/quote]

Surely, a really low pressure is just asking for a burp?

njee20

I generally run 20-25psi, and have run 15 before in 2" XC tyres. That is bloody squirmy admittedly.

I run the same rims and not had a problem yet other than initial inflation. Used Stans tape, valves, sealant and a pair of DD Nobby Nics. Run them down near 23 PSI and not had any issues yet, although they do loose about 1PSI a month.

How tight are your tyre beads on the rims JodyP ?

When inflated for the first time they would pop back off the rim when the air was removed. They were however very well seated on the rim when inflated. Not *touch wood* had issues yet. I may have just been lucky.

Maybe. Maybe I have been unlucky. When my tyre was deflated if I held the top of the tyre in one hand I could easily pull the rim out with the other. I took it back where I got it, they reseated / sealed it and the same thing eventually happened again. I even spent a week in between rides shaking it up and leaving it on its sides overnight too to try to get as much sealant all over around the inside.

I thought this odd because I would have thought a Giant rim / racing Ralph or Nobby nic tubeless combo would be quite common. However I started telling the mechanic in the Giant Shop and he knew what I was going to say before I even finished.

I run at 25 on tubeless and have been as low as 15 when I went by feel, only to discover later that I haven't got a clue when it comes to squeezing tyres. I've got a High Roller II (F) and and Ardent Race (B) on Superstar AM Carbon rims which is a good combination as far as sealing goes. Once you get them on you almost rip your arms out of their sockets trying to get them off.

JodyP

Henry - Might depend on year and rim size. I saw a thread that used Bontrager rim strips on the 29ers so tried the equivalent on my 26" wheels and the strip was too wide for the rim.

Yes, if your BMI was normal you'd perhaps have fewer problems! ;-)

Ok, so I picked my bike up on Tuesday with tubeless setup, took it out for an hour (just round the streets) to have a little play and to spin the sealant round inside. Next morning, front tyre was flat. Pumped it up nice and hard when I got home from work, took it out for spin along the riverside for a few hours (took an inner tube with me just in case) and it was fine. Though, this morning it's flat gain =(

Something they did wrong at the shop or something I've done wrong?
