What mtb sealant should I buy?

Speaking of sealant has anyone used those Muc Off valves that have the side port for sealant? Gimmick or clever? I can’t find a link now but saw it across my FB feed. It has a normal valve for air and then a side port with a tap for sealant. 
 

 

Veyga valves have the same at a fraction of the cost so../

To make a new valve with Clic system seems interesting, wonder if it will take off?

Ive been a long time enduro seal user. But since this My-cycle-life points thing nets you credit at cwc/cycle lab…ive been going there to fetch me some ‘free’ Stans every few months. Its all they have worth getting (except that expensive pink unicorn pee that is Muckoff)

So this past weekend i was cruising along with a friend and we were discussing how long its actually been since our last punctures and whether it was actually needed to top up after that initial seal (gravity tyres dont see many holes). I recently fitted new tyres so i was 150ml in on both wheels. 

Well, Murphy was obviously hiding in the bushes…because i nice neat cut between the blocks meant it was now raining Stans sealant every rotation of the wheel. And thats as far as it went…stans all over my frame all the way down the trail. That watery crap takes forever to plug a hole. 

I wont be bartering for it again…

i’ll go buy an enduro seal 5L instead.

That Happens to me Every Time.

Tried Many Different Sealants.

What I do Now Is Quicky get off the Bike and plug the hole with my finger.

Install a plug and Good to Go.

One of those life lessons for cyclists that most take way too long to learn!

My strategy is to, as you say, stop the leak with my finger and only then decide what to do. Depending on the size of the hole and where it is in the tire .... bead/sidewall sometimes needs some 'inventive' thinking 🤔

Was in a store the other day, asking for a 1l bottle of sealant. They asked me why I needed so much - I have four bikes to maintain. They told me they had a customer come in that had literally filled their tires with sealant and were hoping I wasn't planning to do the same thing...

Janos, Evobikes, knows me well enough .... 2x 1 liter bottles at a time ....

 

Topping up the odd tire before a race use minimal.  Then when I do get to that 3 month service ... 4 of 5 bikes later, that is a lot of sealant !!

 

 

Must admit ... have not tried filling a tyre with it though ...

I managed to get 2l of enduro seal from Durbanville Cyclery for R300 ex shipping.

That's just got a ball valve instead of the check valve arrangement that either Presta or Schrader valves have. Means you can get air in faster, but at the expense of having to control the valve manually - if you just clip the pump head off all the air will escape, likely along with a good shower of sealant.

I'm all for a gadget, but I suspect I'd poke myself in the eye with a pointy stick before committing to that design.

The best design I've seen so far is the Reserve Fillmore - lots of air flow, easy to clear a clog, and stops the air from coming out - but at R 1 500 for a pair that pointy stick is gonna come in handy again.

Have to agree.

 

Not elegant, but I remove the core and slip a tube over the valve with a cyringe on the other end.  Syringe is velcrowed to the spokes.  Now I can measure out and add sealant without any fuss. Clean the inside of the valve with an earbud, fit core, pump up.

 

 

New tyres gets popped on first.

I’m an engineering fool so I’m trying to understand how it works. Being that I have two default modes - Hulk or utterly pathetic - I like the idea of shutting off one thing so I can focus on another thing. The way I see it (from this link) is that you can block the valve off before removing the pump head (or CO2 head) and without having a sensitive valve erm stem? involved. The way I see it from this video is that it will suit both of my modes 😂 

Or is my shoddy engineering brain playing tricks on me?

I like this one. Not many places stock it though.

Or the thicker blue version you get at Midas. Just need to dilute it a bit.

Slime Pro was nice, but I'm not sure if they make it anymore.

Pour it in, seat the tire, pump it up. No need to use syringes. I learnt this from a very experienced mechanic when I was struggling to get a gravel tire to seat properly with soapy water and a compressor. He just poured the sealant in, swirled it around and then inflated it in a horizontal position.

I have done this on a new tyre fit.

 

Topping up .... the syringe works very nice

The best is once you found a cheap product that works well,  just to keep it to yourself and not raving about it on the internet. Once “they” realised the product works actually too good, it disappears from the market…Be cautious guys, “they” are everywhere…😜
