Tubeless rims...aaarrrgghhh.

    Oki, ok, hand up, I'm having trouble with modern tubeless-ready rims. I am stoically sticking to rim brake clinchers, and I like to run a tube. There, I've said it.

    Now - modern & wider tubeless ready rims - sound great on paper - allow for larger tyres, give the option of running a tube or not, and opens the door to slightly better puncture protection (not convinced, but let's paint this as an advantage).

    My gripe is with how bloody difficult it has now become to mount a tyre on these rims - doesn't seem to matter what tyre - I've snapped a set of tyre levers in the last week, and bent half a dozen dessert spoon handles while shouting at the dogs, before reaching gingerly for the elastoplast.

    What gives?????

    What's the knack?

    Is there a tool I'm missing?

    The way I feel right now I'd happily turn my back on tubeless-ready rims and pick up only old school clincher rims from now on - except they're dying out too.

    If I can't change a tyre in the comfort of my living room, how the heck can I expect to change one atop Sally Gap on a frosty January morning?? Makes me not want to risk tubeless rims on any sportive in case I pick up a flat - I'm goosed.

    have a set of Hunt Aero Wide Race and a pair of Mavic Cosmic Elite USTs, and I'm squinting at both with trepidation, and it's not right!!

    Do you mean it’s difficult to get the tyre onto the rim at all, or to seat in the bead correctly when set up tubeless?

    To get them on the rim, this may be way too basic, but have you tried washing up liquid? I always find it helps.

    The difficulty for me is usually trying to get them to seat in the bead correctly when set up tubeless, If that’s your issue, I find fitting them with a tube first, then unseating one side of the tyre only to get the tube out, and then reinflating with a compressor does the trick.

    As for the sportives, I had a tubeless failure in the middle of nowhere in Galway this weekend: two big punctures in the same tyre. I tried everything to avoid having to put a tube in because I was dreading having to refit the tyre with tired, sore hands, but in the end I gave in and honestly it just slid on. Once I inflated the tube it popped into the bead and it’s still grand 150 km later. The sealant sloshing about everywhere did the job of the washing up liquid, I think.

    I'm talking about just getting any modern tyre onto any modern tubeless rim. At this stage doesn't matter whether there's a tube in there or not it seems!

    Mavic UST rims - Jesus Christ folks, you'd want thumbs like iron man. There is clearly a knack to it that I have not acquired.

    So what is it? And no, I won't be carrying around washing up liquid on my spins!! 😂

  • Registered Users Posts: 3,216 ✭✭✭ Breezer

    Well it can go in a small bottle, you don’t need loads 😂

  • Registered Users Posts: 5,634 ✭✭✭ fat bloke

    Amen brother.

    Sell em. Those mavic ust's are a mare. A set of wheels you can't comfortably get a tire are a chocolate teapot.

    Invest in a pair of pre-tubeless normal wheels.

    I find the best trick is to try and get all other areas of the tyre edge toward the centre of the wheel (width), where the diameter is a little less, so you have a bit more room to get the tye over the rim.

    Yep - I'd second this - simply work your way around the wheel, pinching both sides of the tyre (temporarily pushing the tyre bead off the slightly raised sidewalls into the centre channel) - this should give you a little bit of extra slack when it comes to the last bit - doesn't necessarily mean it will be 'easy' but it should be 'easier'.

    There are various tools which can assist you:

    I’ve a set of Mavic UST wheels on which I have 28mm Tufo clinchers. First time seating on i broke skin on two thumbs & the bike shop guy found them extremely difficult to fit.

    Second time round I went straight to lbs to seat the tyre & they have some sort of Giant product that rubs on the rim to allow for easier seating. The tyre popped on in seconds!!!

    Maybe washing liquid would do the same job for you?

    I pray every spin that I don’t puncture btw.

    Yep 100% agree OP. VIttoria Corsa are easier tyres but my VIttoria rubinos, I had to pull them on with a pliers wrapped in duct tape and a bucket of hot water. Have had a couple of punctures, have found one side is usually 'easier' than the other for some reason when trying to get the tube out. By easy I mean almost thumb breaking but not impossible like the other. No idea why. I dread getting punctures, I never really get the pressure needed to reseat them from a handpump. No pop.

    Cheers AxleAddict - some good food for thought there.

    Anyone have any direct experience with any of these tools?

    I struggle to mount GP5000 (tube type) tyres on Zonda 2 way rims. Struggle is putting it mildly. It's a nightmare. Add latex tubes to the mix for added difficulty.

    I find that it definitely helps to get the bead into the well in the rim. A sturdy set of tyre levers is a great asset - I use the Park Tool levers as the regular black things simply aren't up to the task.

    I never used to mind fitting new tyres but my current tyre/rim combo has me dreading it.

    On the other bike I have Fulcrum Racing 3 rims with Michelin Pro4 tyres that almost fit themselves compared to the Zonda 2 way/GP5000 combo.

    Progess, apparently. 🙄

    The best tyre I’ve found for fitting and sealing on the Mavic UST Rims are the Hutchinson Fusion Range. I like the tyre on the road too.

    On a Prime wheelset I use Vitoria Corsa’s, again, they went in pretty handy.

    Ive long given up on GP5000TL, but Schwalbe Pro One aren’t too bad to fit either.

    This 100% was the difference for me, some tyres are still a bit tough but only the last little bit

  • Registered Users Posts: 4,058 ✭✭✭ MojoMaker

    Might try those Hutchison Fusions alright.

    Can't get Schwalbe Pro One, Vittoria Corsa, Vittoria Rubino Pro, or Conti GP4Ks onto either set of rims I have.

    Anyone still making non-tubeless-ready clincher rims anymore? is the only route handbuilt maybe?

  • Registered Users Posts: 2,708 ✭✭✭ De Bhál

    yeah I have that Lifeline Seating Tool and it does the job. Save your thumbs and buy one

  • Registered Users Posts: 325 ✭✭ AxleAddict

    I actually own all four of these (which is why they readily came to mind) - well, actually I don't have the Lifeline Tyre Seating Tool but one very like it from BBB

    Here's a pic which shows them side-by-side and their relative differences in size. The first three should be small enough to take with you on rides (either in a jersey pocket, tool bottle, or saddle bag) - the last one is not very heavy, but it's possibly too bulky to take out on a ride and is more suited for home use (I mean, you could probably fit it in your rear jersey pocket - but not into most average sized saddle bags)

    I'm busy right now, but if I get some time later this evening I'll update with my experiences of each.

    i've never used them tubeless, but i like the hutchinson fusion tyres too (especially when decathlon seemed to mis-price them, i got them for i think €20 each)

    one thing i found with them was that when they reach end of life, they do it quickly - you go from 'hmm, i might need to change that tyre in a month or two' to 'holy ****, that thing is dangerous' in no time.

  • Registered Users Posts: 8,734 ✭✭✭ Macy0161

    I've a version of the pliers on right end, and think they're brilliant. Even coped with Marathon Plus. Be interested to hear about the others @AxleAddict especially the Tyre Key on the far left, which I was tempted for in the Saddle Bag.

  • Registered Users Posts: 6,953 ✭✭✭ CantGetNoSleep

    I'm a tubeless convert but those Mavic UST rims are an absolute disaster - I sold mine on after a week. I got tires on them after an awful lot of trouble (and changing the tire type), but realised that one of the tires I had fitted had a puncture and getting it off was even worse. There was simply no way I would have been able to fit a tube out in the wild. I've had better experience with Hunt's though.

    Fair play AxleAddict, that was certainly comprehensive!

    I'm going to pick up a Tyre Key and the Lifeline tool on that basis.

    On the subject of 'lube' for tyre fitting, and without wishing to gross anyone out, I presume good old fashioned (and free) saliva be a solution in the wild?
