:laugh: :laugh: :laugh: I must be sealing more holes than I realise!! I take your point and if I'm honest I haven't a clue. By "drying up" I was thinking literally of the sealant drying and forming a crust or flaky powder. I'm going to find out............

My buddy's experience of TPU is not great and an expensive lesson!!

A quick Google shows several articles all stating same thing, the sealant is water based so will dry out. Again there are likely to be some which are not water based(?) so maybe not an issue. Going on a quick search most are.

That doesn't seem to make sense
if it is water based it will only dry out if it has a way to evaporate into the air

but it is in a sealed environment so the water will not leave that environment
and if it is - that is called a puncture!

or am I missing something??

I think most tubeless setups need a top up of air every coupld of weeks or so, which means there is fresh air getting in for it to evaporate into.

so the tubeless setup requires a topup every couple of weeks and the sealant needs replacing every x months
and they are difficult to get on and off

all in all - for the average rider that is not bothered about losing a gram in weight and just wants a nice happy ride once or twice a week
they do seem a lot of trouble for little gain

Well I don't think tubeless were necessarily designed with casual cyclist in mind, more the enthusiast. All pros teams I believe are tubeless for added puncture resistance and better rolling resistance but then the riders aren't ones maintaining them.
Lots of recreational cyclists have gone tubeless but without having any data to back this up my guess would be most who class themselves as a casual once or twice a week rider probably won't bother.
Anyway, I don't run tubeless but seem to be contributing more than those that are 😂

Lefty tighty. Get it righty.

Why do people do this? Just trot out nonsense about tubeless? I mean, no ones forcing you to use them. If you don't want to, don't.

I top up my tyres with air whether tubed or tubeless before every ride or at least every couple. So no difference there.

Sealant needs replacing ? Where do you get that from?. I top it up occasionally. I couldn't say how often. Normally if I'm working on something else. Easy job.

My tyres (Cinturato Velo) are no harder or easier to get on/off than my (tubed) Durano Plus.

Saving a gram in weight? Who uses tubeless to save weight? I ride it to not get punctures. And I don't.

I'm not an advocate for tubeless. I do have a bike with tubes too. Nothing wrong with either. But some of if the nonsense on here about it is baffling.

What's happened to Tannus tyres?
Have they lost the battle to tubeless?

I agree absolutely with this. I have been using tubeless for 8 years, in that time I’ve only had three punctures which didn’t seal and required a plug. I have friends who have tried and gone back to tubes and some who dont want to try it. It’s an individual choice no right or wrong, however I believe the biggest issue is that you have take a bit of time to become educated in how it operates and best practices to get the full benefits. In addition I firmly believe some of the sealant being sold are not fit for purpose, certainly some are a lot better than others for road use.

I check my tyre pressures before every ride, how else would one know if there's a problem or not? I've done this for 40+ years in the belief an incorrectly inflated tyre is a problem waiting to happen. Topping up a tubeless tyre is not extra work.

Every six months or so; deflate tyre, remove valve core, place syringe in sealant container and draw up sealant, place syringe in valve and release sealant into tyre, inflate tyre. 30 minutes perhaps?

That's it!!!

Set this against my last but one set of road tyres; one tyre had seven sealed punctures that I knew nothing about! I can fix a puncture on tubeless in 5 minutes, 10 maximum. I can't achieve this on a tubed tyre.
