Tubeless road - it actually works

do people have saddle bags with stuff in it who run tubeless? I have just stans darts, Co2 & pump, have never had a problem, I would never get a tube in so my only saviour would be the darts but have never used them. ( The wheels have sealer in them) Curious if people have used stans darts

Can anyone recommend a tubeless tyre that works well with Mavic UST rims? For training... longevity more important than grip.

I've used the Yksion Pro and also the Hutchinson Fusion 5 Performance. Both were easy to set up but longevity was very poor.

I have GP5000TL on my carbon Prime RP50 racing wheels. Almost Impossible to seat on the rim despite using all the tricks. I've heard from numerous people that these are hard to seat.

conti are awful designed a tyre for tubeless compliance isn't right, personally like the mavic yksion 2nd one lasted quiet long, its only the gravel that seems to cut it up. the tubeless tyres are never going last as long as a clincher gp4000

Hi,
Earlier tonight I noticed a bubble, thumbnail size on my rear wheel.
Decided not to chance it and replaced it with tube/tyre.

Might see can I get a replacement from Mavic, despite being a year old, I'd say the tyre has barely 1,000km on it.

From what I've read, this bubbling is not caused by wear but a manufacturing fault.
Has this happened to anyone else?

Found taking off the tyre, inserting a tube and reseating with non tubeless tyre very straightforward, given the horror stories I've heard about tubeless I was pleasantly surprised.

I have the dynaplug one - only had to use it once but it worked a treat.

See a previous post of mne in answer to your first question:

That happened to me with three consecutive mavic tubeless tyres. Rear wheel bubbling, and not after many miles either. I eventually did as you did and went tube and tyre on the UST rims but the tyre was not easily mounted. Ended up walking a short ish (couple of k) distance home one evening after a long spin when my tired hands simply couldn't get a fresh tube in and the tyre back on.

I made the switch to tubeless last November and in my opinion of all the technically advances or upgrades that have been done or can be done this is without doubt one of the best
I done just over 12000 km on two sets of wheels using Continental GP 5000 tyres with only one puncture and one rim strip fail
which compared to 8 punctures in the last 2000 km using conti's 4 seasons is a joy to behold for me and has made feel that punctures may be thing of the past or at the very least infrequent

I think the GP5000 tyres are a super tyre with a very supple ride quality though I have gone from 23c to 25c so that might have helped as well
The grip is fantastic and has allowed me to enter and exit out of corners with more speed than I would have normally been able to before
Mileage wise obviously given that they would be classed as a race tyre don't last as long as the 4 seasons but give a respectable innings
Of the 3 tyres I changed so far 2 rears 3700 & 3250 Km and 1 front at 5200 Km (the front was only changed due to a side wall puncture that wasn't sealing)
I reckon when cycling in North Wicklow given that the roads are so bad 5.5k for the front and 3k for the rear is about all I can expect from these tyres
On better roads I would expect nearly 7k from the front and a good 4k on the rear but of course it all depends on the type of riding your doing as well

My only one down side is fitting the tyres, for me they are nearly impossible to fit and I have at this stage given up carrying a spare tube because there isn't a hope in hell of me fixing a roadside puncture this way
Instead I carry a Stans plug set but thankfully as of now I haven't had a puncture so not sure how that's going to work out for me
The 3 tyres that were changed were brought to my mechanic and normally he can pop tyres on with his hands but not these, Zip ties and tyre levers were required and even then it wasn't easy change over

Sorry, but for me those two statements are incompatible and the very reason why I bailed out of tubeless tyre use.

What is the consensus on best tires at the moment? I've a Cadex set that I'm going to change, have Schwalbe Pro Ones on another bike and they are fine so far, don't want to go for GP5000s. I see some Pirellis getting good reviews but not sure how much of this is just marketing

I'm trying to mount tubeless for the first time today...going as bad as I expected.

My bike is already tubeless but the stock Cadex tire needs repairing after 300km, so I'm trying to fit Schwalbe Pro Ones.

I have a tubeless pump, and have tried any tricks on the internet like soap and water, putting in sealant, removing valve core etc. Don't have a tube to fit that.

Tires went on and off ok. When I try to inflate using the tubeless chamber, it does inflate but air escapes from one part of the tire, just between the bead and the rim. It isn't seating correctly, almost sort of half seating. You can tell by the look of the tire that it isn't seated correctly as there is a small indicator line.

Anything else I can try, beyond swearing more loudly?

Put a tube in it.

Thanks for the replies - it doesn't seem to be the valve lock ring. I can pump up the tire and it even held air overnight but once it goes above 60psi or so, sealant just starts spitting out where the bead meets the rim, and you can tell from the logo that the side of the tire opposite the valve just isn't sitting correctly on both sides of the rim (the Schwalbe logo isn't even visible correctly).

I only quickly cleaned off the old sealant on first inflation so I wonder is some old sealant stopping the bead sealing against the rim. Other than that my only theories are rim tape damaged, or worst case scenario I've damaged the bead with a tire lever when installing.

I'll try a tube this evening I think

Can anyone help me here? This is with a tube in - but it looks exactly the same as it did on my very first go of mounting it tubeless with a tubeless pump.

You can see from the last photo that it looks to be seated perfectly fine by the valve and the rest of the way around, but at the logo on the other side (both sides of rim) it is clearly not seating correctly, even with the tube. There is an indicator line to show where it should sit but that doesn't show at the logo opposite the valve side.

Rim only has 350km and hasn't been crashed or hit a pothole etc, rim tape looks perfect too.

What sort of pressure are you at? Keep pumping until it seats properly. Little bit of soapy water might help.

I've tried 160psi from a tubeless pump and even that won't work

If another tire fits on fine it's a duff tire. If the second tire doesn't seat in the same place it's a bad rim

this is why i'm big fan of Mavic UST, with their approved rules no faf, wheel pops on after few pumps and little faff.

Have to agree, found taking the tyres on and off very straightforward.
My only issue was getting a bubble/blister on the rear tyre. The shop gave me a replacement. It seems to be a fault/problem with Mavics own tyres, pity as otherwise I found them very good.

While I was waiting on the new tyre I put on clinchers and tubes and they went on surprisingly easy too.

Got it on eventually (with tube) by pushing at the bead and going beyond 160psi. Was waiting for tube to pop tbh. Will try to unseat one side, remove or even cut out the tube, and keep it on tubeless once I build back up my stores of patience

I'm finally sorted (I hope). Left it in with the tube for two days (for patience not any technical reasons), unseated one side, soapy water, one side back on (wasn't the easiest), , valve back in, tubeless pump, seated first go, removed valve core, sealant, tubeless pump again, seems to be seated and holding air.

Now I just have to do the rear - the front tire would have needed a repair anyway as it got a puncture that wasn't sealing. I'll have to live with non matched tires for a few days
