We had a guy go through 2 latex tubes with two punctures yesterday (the first with a mighty POP). It's over a year since I've ridden with someone that had a puncture with tubeless (that we knew of).

Tubeless isn't perfect, but I've never had a ride stopped for more than 20secs with someone on tubeless.

i have about 2 flats a year on latex with a mix of GP5000's and corsa speeds.

the time when your at the side of the road with some numpty on tubless, st spraying everywere as it wont seal, him jamming plugs into it and then giving up and having to put a tube in it anwyay.

thats when you realise tubeless is stupid.

I've not had a flat that I've known about in 5 years on tubeless.

And not only have I've never had a 'st spraying' tubeless issue, neither has anyone I've ridden with.

We have however had multiple 20min delays when someone hasn't got a spare, can't fit their spare, hasn't checked the tube & re-punctures, doesn't have a value extender/right length valves etc.

The longest issue I've ever had with a tubeless rider was a gravel bonanza 2 years ago when a guy got a thorny twig stuck in his read tyre. Stopped, pulled the twig out, span the wheel to seal it, got moving. The rest of us didn't even stop and never lost sight of him.


You can like or not like tubeless, but pointless they most certainly are not, and not just because they have a very clear and obvious point to them.

If I had tubeless, I would not have had to stop a 100m sportive 50miles last week - to faff around trying to sort a puncture/repair/etc. then a slow 10miles to feed station (where there was a mech with track pump) with low pressure (mini pumps aren't great biggrin) to get up to proper pressure and then I could speed up again.

Tubeless is most cases you won't even know you've got a puncture and can finish ride/event in time/speed you want.

Exactly that, and what has happened to me when mine have gone. Other than I could never put tubes in mine as the dynaplugs have a brass nipped which won't detach once in (otherwise it all opens up again). So if plugging doesn't work it is walk / train.

Latex tubes are awful, zero puncture protection with decent tyres. We have a lot of flint on the roads in our area (York wolds) so you will end up with quite a few cuts that latex tubes cannot handle ... tubeless certainly cope with these smaller cuts with a decent amount of success without needing to plug them.

2 weeks odd in and the tyres have really transformed the bike. I am very impressed.

Spending 45 mins on a 5 min job and not having the right pump isn't really the tyre's fault though.

Takes a while to pump up with a tiny mini-pump. I forgot the co2 as well biggrin That's on me.

But it took me a few mins to get the tyre off and find what it was that caused the puncture (no point putting in new tube until I had).

Regardless of whether it delayed me 10m or 40m, with tubeless I would not have had to stop at all as would have sealed something like this no problem.

Any thread on tubeless problems will always go this way.. bunch of different ideas on how to set up followed by someone throwing in the ‘tubeless is ste’ comment…

In my experience continental gp5000’s will go on if you just squirt a bit of soapy water round the bead…

Secondly the whole ‘you need to put sealant in to get them to hold air’ argument is only true if you can’t be arsed to be meticulous in your initial set up. A new tyre, on a well set up rim will and should hold air. If you are expecting the sealant to seal up poor rim tape set up etc it will likely fair prematurely.

I always seat the tyre, check it holds air reasonably (it will lose a bit) and then add sealant by removing the valve core once I’m satisfied the tyre holds its own.

Have to say the rear would not seat / seal until sealant was added. And it was blown on correctly (dry).

It deflated numerous times, in sequence. Added sealant and rode, held perfectly. Another lesson learnt that I didn't even know was a lesson.
