Just got back from a epic day of riding a bike park and then a little enduro ride after…
Only negative being is that I had to walk 5 miles back to my truck as I got another puncture again.
This has happened twice on the trot and enough is enough!
Not used tyre sealant before so I don’t know what sealant to actually get??? My bike is a mullet set up 3rd gen levo. So how much sealant do I use on a 29er and a 27.5????
Also what sealant should I get?? Recommendations needed plz and ty

You’ll probably get a million different recommendations but for what it’s worth I use orange sealant. I bought the small 4oz bottle with injector, enough for one tyre then I refill it from a big bottle. Hardly any mess either as you can pump in through the valve hole.

I just buy muc off by the litre these days. Used to use Stans but for some reason the last couple of punctures I had with it just kept pissing the sealant out until the tyre went flat anyway..
downside of muc off is that if you get it on anything, it becomes flourescent pink.
probably try peatys next

Are you saying you are running tubes and want to go tubeless? I use muc off.
Yes 2nd puncture I have had in the last 2 rides out.
Done some quick research, I also need a valve core removing tool liquid sealant and a canister pump, but I have found out that my track pump will be suitable with an air shot tubeless tyre inflater after a quick google search

what tyres are you using? the tyres that came on my levo would puncture if you rode within 10m of sharp rocks and I was having the same until I changed them.

Which ever sealant your pick (Stans is the best cuz they were the first and they cost the most ;)), you will have to stick with the same product as they don't mix. You should also pickup some Bacon Strips for holes that won't seal with sealant alone.

I use Stans. Have done for years. Seems to work well and doesn't dry up inside the tyre.

You can get a complete kit that will come with new valves, tape and sealant.

Your rims might already be taped. Mine were (Orbea Rise), meaning that you would only need valves and sealant.

Some tyre/ rim combos are easy to set up. Some are a complete nightmare.

Air shot inflator thing is a good idea but you might get by without it. Particularly if you're using your existing tyres.

My tyres are standard specialized tyres that came with the bike, rims are all taped up as standard and I have the valves in my specialised bag so all I need is sealant valve core tool…
Ok
I search for stand tyre sealant today and order some….
Will be changing out tyres but can’t do this until I get exmas out the way, so tubeless is only way I can go for now

I carry a Stan's DART (Dual Action Repair for Tubeless). It has a kind of chimney sweep's brush with a barb for positive engagement to plug the hole, and a coating that reacts with ammonia sealent (e.g. Stans) to bond it all together. Not cheap, but the one time I have used it was to seal a sidewall split about 5mm long which lasted the life of the tyre. It also has a valve core removal tool built in. To mount a tyre I now use a tube to pop the beads, then deflate, release one side, remove tube fit, valve, and, with one side seated, only half as much air to escape so much easier to get it sealed. As a last resort, if my Air Shot still can't get the tyre seated, I use a co2 inflator, but, replace the CO2 with air (as Stans recommends) since it can react with the sealant. Don't use Stans Race sealant as it dries up really quick.

I used stans for years but I changed for a few reasons
1st it would bleed through sidewalls on some tyres Maxxis being the biggest culprit
2nd it failed to seal some simple punctures
and last but not least it corroded one of my rims where there was bare alloy by a valve hole

Muc off has done none of the above a year in use so will be sticking with it.

Thank you for all this info

I am a recent tubeless convert, I use Stans cos it looks like it was invented in a shed in Rochdale, I did the first tire seating at the petrol garage, had to do it again, so I got a Milkit booster tank, it sucks big dogs balls, terrible design, so I went to get a bontrager booster pump, I must say the design is better with the flip lever, better than the twist dial on the joe blow, easy to flip on and off. I likee that I can pump it up, and then put the pump head on the valve afterwards, and hold it steady, which is good for just regular inflation.
It wasn't cheap, but makes things simpler in the future.
Don't forget your soapy water!
I got a big bottle of Stans, plus the Stans little bottle, you can use it to put the sealant in the valve with it.

Halfords will fill your tyres with slime for £10 a wheel and say 18 months no puncture’s.
I think that's filling the inner tubes with slime rather than tubeless.

Slime tubes are excellent but it means you're still running with inner tubes though.

It's a good half way point but tubeless has more advantages I think.

The trouble with slime in an innertube is that as long as the cause of the puncture stays in the tyre the innertube hole is continuously reopened while riding.
On one of my bikes which didn't have tubeless ready tyres I used slime in an innertube but when the tyre got a small shard of stone imbedded in it the stone just kept opening the wound in the tube. This also happened with a thorn.
I tried fitting puncture resistant tape in the tyre but they are very difficult to install and too narrow for most MTB tyres so I still got punctures and I have resigned myself to fixing the punctures while riding until I fit a tubeless tyre.
In my experience the only cure for punctures is to go tubeless with proper tubeless ready tyres. I have tried to make non-tubeless tyres tubeless but during storage in my shed the tubeless sealant soaks into the tyre causing large blisters.
