Hi guys.
I'm new to tubulars and have ridden 1165km so far on Conto Comps. I had 25ml of Stans in each tyre and yesterday got a puncture in the rear of about 2mm. Don't know how much it helped as most of it was all over the bike. I put about 3/4 of a can of Mariposa in,with my hand over the whole to stop it coming out, span the wheel a few times, waited a while then slowly rode home as the tyre was still quite soft. When I got home the pressure was 20psi. The next day I inflated the tyre but soon as I reached 60psi the Mariposa and air just kept coming out.
I read on here it's a good product, did neither work due to the butyl tube.
I have now put on Veloflex Carbons, so will the Mariposa work better, also I thought I saw on here, correct me if I'm wrong, that stans shouldn't be added to latex.
Any info would be greatly appreciated, as I'm still learning.
Cheers :D

the only sealant i've ever found effective is tufo extreme, it's currently keeping both front and rear conti comps going through multiple punctures

it works fine with veloflex (actually i think it works even better with veloflex than with the comps, perhaps due to the latex tube in the former)

before use you need to shake it hard to mix it, it's got a lot of fibre/whatever in it, it can form quite a substantial plug, make sure it doesn't get in the valve core as it can seal it too!

don't use it as preventative, it dries out faster than tubeless-oriented sealants

Awesome, thanks for the info. I'll try to get some to carry with me. Might even start taking a light spare tufo tyre, like some do on here, easy to change when using tape, oops I shouldn't have mention that. Lol. !!

I find it interesting as to the sealants being sworn by, etc. Right now I'm using OrangeSeal. It has worked for me. It has different sized particles in it and needs to be shaken up well for sure. It is in quite a liquid base and doesn't seem to harden up (I've never had a tube stick itself together with OrangeSeal). One of the best features about OrangeSeal in my mind is the way you get it in the tube... remove the valve core, and with the little extension hose that comes with it the process is very clean. I only use sealant after a puncture, not as a preventative measure. But once the first puncture has occurred and sealant is in there, then potential use of that tire as an eventual spare is gone anyway, so at that point it becomes preventative if I put enough in. But I usually only put about 15ml or so in, then let it flow to the puncture area and hope it works. It has for me, although sometimes I think its not going to work and have had to keep stopping to put more air in, but once home and let it sit for a day or so, it seems to have fixed it for good.

I tired Vittoria Pittstop early on and that was a horrific experience, perhaps because of inexperience, but it was a laughable scene for sure when, under the pressure of the Pittstop can, sealant was spraying everywhere... out the valve, out the puncture... laughable. I wasn't far from home so just walked home, then tried pumping the tire up and eventually the sealant in there did fix the puncture, but I did not find the experience of the high pressure sealant injection system to be very positive. So done with that.

Also have used Stans... seems ok as well... it worked, but doesn't have a little handy injection hose to use when on the road. That is one reason I switched to OrangeSeal. The other is that so many reviews etc have raved about the stuff. So far it's working for me.

Tufo and Tufo Extreme (or is it just Extreme now?)... I've use this too. It worked as well, but it was very late in the season when I used it, and the latex tube went flat from non use, and the stuff settled in one area and coagulated to a hard mass, and stuck the tube to itself from the inside. OrangeSeal doesn't seem to do that although since that experience I don't think I've let any tires with sealant in them sit long enough for that to really occur.

But here's the relevant thing... I cannot say for sure if one is better than the other, as I'm going off quite a small number of my own experiences. They've all worked. Currently I'm using OrangeSeal and carrying it in a Tufo bottle, because OrangeSeal doesn't make it in easily packable bottles (I've asked them why, didn't hear back). But I don't have the benefit of a large test of each sealant in each circumstance I've had to really say one is better than the other. The main factors for me are how easy is to use on the road, can I carry it easily, and does it hold up so that I can hopefully keep riding the tire till it wears out.

I think next batch I get I might try the tufo extreme with the OrangeSeal injector system... a mix and match. As I try to use just enough sealant to fix the puncture of the moment, perhaps the fact that Tufo tends to harden up at the bottom of the tire if left some time won't matter as much, since I'm only using a small amount. I don't know. But if it seals it quickly at the scene of the crime, then I'd be interested in giving it a try.

My complete "on the road" toolkit... note the OrangeSeal cap on the small Tufo bottle filled with OrangeSeal...

Cal, what kind of air do you carry, or do you inflate using your massive lungs? :lol:

Ha! Actually that's a really good point. I use air. Natural air through a Lezyne Road Drive pump. Much more controlled as you try to ascertain if the sealant is doing its job or not. With CO2 I think it's much more likely to blow out the puncture before the sealant can even do its thing. And you can easily run out of C02 or something goes wrong where you need to find a gas station for air (that's why I also have the little presta/schrader adaptor in my toolkit. But there's always plenty of air around as long as you've got a pump with you.... it's not too obtrusive...

yes, the tufo extreme will certainly stick up a tube if allowed to deflate, then it will be destroyed on inflation

i had no success with orange seal (it was the 'endurance' type, not sure how they vary)

but i copied their injection method :) i used a couple of pieces of pvc tubing bonded together, the narrower one fits the tufo nozzle, the larger one fits the valve stem, certainly makes it easy to inject with less chance of spillage

it's hard to judge, but i estimate i use about a third of a bottle of tufo if i get a flat

Yeah, that's about how much I use as well, so in the 50ml bottle I pictured I guess that's around 15ml or so. But I certainly hate it when stuff is overfilled as it can come squirting out the valve and gunk things up when you're just pumping up your tires normally after that. And good job on the makeshift "injector hose". That's what I'd do too if I didn't have the OrangeSeal one. Yes, I just checked my Orange Seal bottle and it says "Endurance" on it as well. I don't think there are two versions... I think they just added some more varied size particles in the mix (maybe some bigger pieces?), and for marketing purposes had to let people know that it was new and improved so stuck "Endurance" on the label. Maybe a similar scenario with Tufo and Tufo "Extreme"? But I will think I will try the Tufo Extreme next time, since I don't use much of it, and even then only when I puncture. I will say that after fixing a puncture with OrangeSeal there have been a couple of times when riding in a group weeks later that I punctured again and yelled "flat", but by the time we had slowed down it had already fixed itself, and that was kinda nice, for everyone.

At least with sealant in tubulars, the sealant stays inside. I've seen a few disastrous attempts at fixing a "tubeless" clincher roadside which was filled with sealant. Couldn't help but laugh at the mess that ensued and in the end he still had to fix it by installing a normal inner tube since he couldn't get it to seat properly. And that was in good dry conditions, I'd hate to think about the swearing that would have occurred had it been nasty weather. Then of course you have the sealant all over the place between the normal inner tube and the tire. I don't get the use of tubeless on road. For me, it's either tubular or standard clincher with inner tube.

Thanks again guys for the info, much appreciated, especially you calnago your posts as always are so detailed and informative, great for us newbies.
Can you not put the orange seal in the Tufo bottle once empty and insert using the nozzle instead of attaching the injection hose off the orange bottle.

That Tufo bottle in my pic is in fact filled with OrangeSeal, but the Orange seal cap and hose is just very convenient so I use it. It will only take you one attempt at trying to squirt Tufo from it's own nozzle into the open valve core to realize how much more convenient the little hose is. And you don't have to use the OrangeSeal hose, I just already had it. SunGod's makeshift hose would work just as well. One thing the new OrangeSeal bottles come with is a little cleaner (the long skinny black thing within the hose in my pics above) which makes cleaning out clogged nozzles or valves very easy. At the end of the day, I rarely puncture, but I like to be prepared for when I do.

And appreciate the kudos, thanks! :beerchug:

Setting aside any discussions relating to tyre feel and performance, it's about puncture survivability. You're right that putting an inner tube into a tubeless tyre that contained sealant is messy but it is also do-able and I've done it. On the other hand, about 4 out of 5 tyre intrusions that would have had me stopped at the roadside with clincher+inner are handled by the sealant with at worse some pressure loss easily remedied by something like that Lezyne Road Drive.

Is how I see it.

No problem calnago. Yes I did see the cleaning stick, great idea. I'll get both bottles and re-use the hose on the Tufo bottle and see how I go. Carrying a small bottle will help as well.
Off for a ride now on the new Carbon tyres with The crappy Mariposa so fingers crossed no punctures.
Thanks again guys.

Re "puncture survivability" and tubeless... Fair enough.

I retired a Veloflex Arenberg this afternoon so I decided I would test some bontreger TLR sealant.
Puncturing the tire took a bit of effort but did so in two places using a fairly large puncturing tool.

Removed the valve core
Put in 20cc of sealant
Inflated using entire co2 with plenty of pressure.

Held perfectly with plenty of pressure.

Happy with the results and more confident now to run tubulars year roind
