Going tubeless

My MTB came with tubeless ready tyres and rims and inner tubes installed.

I've been riding it for a year and only had one problem with the valve, which got damaged by a rock on a very fast decent, which resulted in a flat. Otherwise - no punctures.

There is plenty of advice on the internet why one should convert to tubeless - greatly improved puncture resistance, rolling resistance and weight, to mention a few.

But so far my need to convert to tubeless is overwhelmed by my confidence patching up inner tubes.

Yet, I'm kind of curious what do people think about tubeless? Is it worth it?

How much extra work and maintenance does it involve? I've heard that you have to top up the sealant regularly.

Anything else?

On the puncture side, a lot depends on your local area. If you usually find it's thorns, great. The slime-type solutions work well. Round me it's flints, which tend ot put a cut of 5-10mm in a tyre. These are impossible to re-seal (you have to use the anchovy thingies) and it seems to take as long as swapping a tube.

Another problem with tubeless; if you go flat you will need an air compressor to re-inflate.

Yes if you take off the tyre (or at least unseat the beads) you may well do.

If you can sort the cause in situ - extra sealant, "anchovies", etc. - then an ordinary pump will do the job.

If you have to add a tube that should help to seat the tyre as you inflate it as the effect of adding air pressure into a tube will be different to adding the pressure while tubeless - air in a tube presses out in all directions, but is contained by the tube. In a tubeless system it is tending more to just "look" for a means of escape (the blast from a compressor just gives an extra quick push of air pressure to effect the seal before too much escapes).

Im Just about to try it on a bike. It sounds like the bike should be used regularly otherwise the sealant can coagulate in a lump at the bottom. Finish line sells a type of sealant that is supposed to not need refreshing so often as its not latex based.
You will have to make sure your rims are also tubeless ready. Eg if they are mavic ust rims or do you need to apply some gorilla tape or other tubeless specific tape. If out on a long ride you can take a spare tube and fit it in case of major tubeless malfunction. A syringe to measure and inject the sealant through the valve (after core removed) might be usefull.
The guy over at rolling resistance dot com recons its the future which is what got me to consider it properly.
I dont think its a case of topping up sealant rather changeing it as it gets old after 6 months or so from what i hear.

edit that, elsewhere on here people say topping up every 6 months rather than replacing is how to do it.

Let me know what you think of the Finish Line sealant. I've read reports that it's too thick and does not seal the punctures easily.

I've also heard of riders using agricultural tyre sealant OKO, which is non silicon based and is a lot cheaper than Finish Line. Apperantly one can "water down" OKO sealant so it works well on bicycle tyres.
