Tubeless Tyres -"saying the same things about tubeless tyres over and over again" Hippy read the first f**king post

Your anecdote is nice but I'm still not going to run road tubeless.

I won't lose any sleep

I've had one puncture on my 25c GP4000iis, so what?

nice anecdote is nice.

This was the article I was looking for the other day re valves:
https://www.bikeradar.com/features/this-is-why-its-time-to-stop-using-presta-valves/

so what?

So what's the disadvantage of tubeless for road that's made you decide it's no good without trying it?

If you like the bukkake look for your bikes I highly recommend road tubeless :)

Why would I change my technology if it's not failing me? To me that sounds like an exercise in boredom and a burdensome wallet. I'd prefer that time riding my bike and afford some nice groceries.

That reminds me; also, the times I've ridden with people running tubeless (following their wheel) I've ended up covered in jizz. Can't remember the last time someone's inner tube slapped me round the chops.

I can arrange it but it'll cost extra over the usual agreement... ;-)

Which is what you get when you've had several punctures seal themselves without you having to stop and change or patch a tube.
Not trying to convert you. I just wouldn't go back to tubes unless in an emergency.
Cost wise, it was £15 for a pair of valves which can be reused basically forever, and about the same again for a bottle of sealant which has set up 5 or 6 tyres.

There's also environmental impact concerns. I rarely patched tubes which I should have done more of but eventually they go in the bin and I think something like 96% of London's bin waste gets incinerated. Sealant is mostly latex which is biodegradable in UV light and Stans I believe has some sand in it. And plastic bottles are recyclable (if we didn't ship it abroad to be landfilled somewhere else under the label of recycling)

That's fine but tubes and tyres are consumables, and if you bought your rims in the last few years there's a fair chance they're tubeless compatible.

No one is saying you have to sell all your shit to change over, but it just comes down to what you buy to replace (which at some point you'll need to).

Concerned with the environment but rarely patched tubes? :S

I'm surprised but there's actually a massive article on this:
https://www.bikeradar.com/features/tubeless-sealant-environmental-impact/

It doesn't work for me. We can explain each others point of view til one of us expires but tubes cost me £2, sealant IS messy, and I've just had a catastrophic failure riding Gravel tyres tubeless for the first time. Why would I then try road?
The inner tube has been working pretty damn well for over a hundred years.

This has been a huge concern of mine also, I used to work at the EA and helped processing a project researching how much of a certain chemical from de-icer ran off into the water systems and ended up in food. Will save this for later, thanks.

Oh yeah fine, don't get me wrong if you prefer tubes then go for it - I'm not some sort of evangelist. I just don't see cost of switching as a big factor given costs aren't dissimilar

I realise this sounds very old man Tom of me and I can be a technophobe sometimes (mostly because marketing promises much more than tech can ever deliver in order to sell products - although that's another discussion entirely) but I consider it crucial.

A local river here has been severely polluted by runoff from the airport cargo terminal. More cargo planes due to more online shopping and the de-icer just washed straight into the waterways.

It's the C02 rather than the ice. If I have to use one to seat a tyre, I then deflate and use a pump

I've ridden tubeless road for years. I was an early adopter, got several rides stopped because the tire won't stop leaking, co2 froze my sealant, worms got expelled, tire went unmounted and won't go up again, forgot to top up. Any tubeless drama you can think of I probably had it before. At the end I was carrying more spares than I would with tubes, got jizzed over too often and every flat was a lottery. A steep learning experience, but for the few times I flat over a year I'd rather put a fresh tube and keep going.

Tubeless is the new helmet thread :D

Verdict, stans dart aren't just overpriced, but are over hyped and shit. The cheap worms are far more effective.

I have 40mm maxxis velocita tyres on wtb i19 rims. Two layers of tessa tape. These have held air and been fine. Topped up with Orange Seal Endurance often.

I’m getting intermittent air leaks. The rear will lose air pretty quickly (maybe 5psi and hour) above 20 psi.

What to tinker with first? Valves?

When fitting the valves it’s not easy to know how hard to force the rubber bung in. I presume they will split if forced too much?

Any insight welcome.

Sorry to hear you struggled with them.

Do you have any experience with the dynaplug stuff? I've found these worked more easily compared to the cheap worm and pronged tool at least on skinnier tyres.

No. I should try them. This is 9n mtb I should say. The cheap worms seem to last forever.
