Tubeless newbie

    A few weeks ago had some swchalbe tubeless which were fantastic although disappointingly on the way home tonight I had a puncture it doesn’t seem massive and compared to the “nail through the tyre test” didn’t seem a lot only about 3mm x 1mm Sealant went everywhere initially I got off and span the tyre a bit no joy. Running a tube in there now. 

    Now I’m worried if the tyre is buggered and if I missed something after getting the puncture. Anyone got any tips? 

    3 years on Duranos not one puncture. 3 weeks on tubeless one potentially ruined tyre.

    I’ve had a couple of big cuts

    I’ve had a couple of big cuts on my S–Ones, on the sidewalls where they never really fixed. I tried those “rope plug” kits, all they did was pop out and make the hole bigger

    I’ve got these for repairs now, just really hefty patches:

    I had the same problem.  It was the rim tape in the end. 

    Not saying you have the same problem but try a new rim tape. 

    Not all of them are the same quality and sometimes while we are trying to change the tyre we can damage the tape unknowingly. 

    I feel much more secure with my tubeless than clinchers.  Currently I am running the old Schwalbe S-Ones and they seem to be quite good all round.

    For bigger cuts on tubeless I

    For bigger cuts on tubeless I use superglue, believe it or not. Squeeze the tyre so the hole ‘gapes’ and swipe in a little superglue. Give it time to harden. You’re not closing the hole with the glue, (you can’t, the glue will dry hard and the tyre will flex and the bond will fail) but you are making it smaller so that the sealant has something to ‘bridge’. Pump the tyre like hell to force through the remaining sealant. It has helped me about half the time and the weight/cost/effort is almost zero. I buy superglue multipacks from Poundland.

    I do this with the tubs I run on the summer bike too (before using a can of Effeto Mariposa).

    Had similar challenges

    Had similar challenges getting tubeless to re-seat after topping up sealant. Ended up taking it to my LBS (who happen to be a Hunt / Tubeless dealer). Their air-line wouldn’t ‘pop’ one of the tyres, so they’ve built up the rim a bit with more tape.

    This reduces required air volume, and encourages the bead onto the rim sidewall, rather than sitting in the middle of the gulley of the rim.

     

    There’s only so long you can pump up air chambers, soap tyres, use inners to ‘stretch’ tyres, and generally swear – whilst reading the words ‘easy tubeless ‘ on the One-Pros!

    The ability to seal is very

    The ability to seal is very sealant dependent.  You can try some tricks like adding glitter to your sealant to help it seal larger holes.  That said, 3mm x 1mm is a fairly sizable hole, you may need to get one of those “rope plug” kits to fix the tire, I am not sure any sealant would reliably seal a hole of that size.

    The main advantage of tubeless on road (as I see it) is being able to run thin supple tires (which greatly reduces rolling resistance and increases comfort) while having some puncture protection. You probably give up 20-30 watts running Durano  over Pro-one tires. Trying to run the same type of tire tubed would result in even lower reliability than you see now.

    If reducing punctures is your primary goal then Durano is probably a better choice, you can even get a tubeless version which should be even more bomb proof as any small holes that make it through the tire breaker can get sealed.  You will however take a hit in rolling resistance for the added security (there are no free lunches).

    The Pro-one’s are quite thin fragile tires as they are racing tires.  Tubeless setup makes them more reliable than they would be otherwise, but it really is a relative scale.

    You dont say what tire you
    You dont say what tire you are actually running. The S-one is generally the best overall, and is pretty much indestructible. If its a small cut like you describe then the sealant should take care of it, providing there is enough in the tire. For a 700c road tire you generally want about 40-50 ml. Failing that there are tubeless tire repair kits, by Genuine Innovations; basically its a strip of rubber that you jam in the hole with a little poker supplied with it. Work a treat. The problem you describe sounds an easy fix whatever.

    Schwalbe Pro One? I got a

    Schwalbe Pro One? I got a pair of them. Felt fantastic, and then I realised that they’re like tissue paper. Guess it’s fine if they seal, but only to a point – you still lose the air and a load of sealant.

    Plus I clearly had a manufacturing fault in one of them – I wonder if there was a problem with the liner or something similar, because there were weird bulges at parts of the tyre. Like blisters just under the surface. I tried patching the inside of the trye, but it didn’t do any good.

    A bit part of me really wants to replace it, but looking at the reviews, it seems like so many other people are also having problems with durability. 

    The summer bike’s been put away for a few months. I’ve still got the one surviving Pro One on the back, with a GP4000s on the front. I’m off to Mallorca in a few weeks time. What I *want* to do is replace the knackered Pro One. But I’m thinking that what I actually should do is ditch the remaining Pro One and swap it for another GP4000s.

    I’m totally sold on the concept of tubeless. I just don’t know if there’s a road tyre out there that’s at that GP4000s sweet-spot of being nice enough for the summer bike, but still offering a degree of durability.

    Tyre is fine with a hole like that, you either had too little sealant or the hole was just too big to seal.  Tubeless arent immune from punctures, they offer better rolling resistance and eliminates pinch flats.  I have had thorn punctures and they have sealed fine, but bigger, who knows.  The other benefit is that tubeless is much less to suddenly deflate(pop), crtitical in safety especially when travelling at speed or downhill.
