muc-off tubeless sealant?
Moderator: robbosmans
I've only used Effeto Mariposa Caffelatex for 5 years and will be sticking with it. It's not perfect as it dries out fairly quickly and clogs valves, but it does its job sealing small holes (mainly flint induced) in 25mm (winter - frame clearance issue) and 28mm (summer) Conti GP5000 STR road tyres (previously rode IRC, but the Conti's are a marked improvement) Anything that doesn't seal quickly or opens up again gets a Dynaplug.

This. I would've given up on tubeless long ago if it wasn't for these guys. So good they can make a hole airtight even if your sealant has dried up. Needing to fit a tube is a very remote prospect if you've got a few of these in your kit.
I currently carry a mega-pill, which is not the most weightweenie friendly, but I like the preloaded tubes and the little blade for cutting the tails to stop them catching the frame or brake caliper.
I've only used 3 sealants: Orange Seal regular and endurance and Milkit. Of the 3, OS Endurance was the only one that I had sealing problems with. I think if OS Endurance stays in your tire too long, it fails to seal. I'm currently using Milkit and have gone through a 1 liter bottle without a flat. I will probably go back to OS regular if I have problems but right now I like other qualities of Milkit over OS (doesn't need shaking, long shelf life and lasts longer in the tire, CO2 compatible, easier to clean up...), but in the end, sealing ability is the most important criterion.

I've found the Conti's much easier to mount and get seated - both from new and out in the field if I've needed to put a tube in (now not needed as Dynaplug works so well with big holes). I could probably get away without using washing up liquid to get them seated. I can also remove any dried up sealant from the inside of the tyre much more easily than IRC tyres. And they just seem to roll better. I'm using them on HED Belgium Plus (28mm) and DT R460 (25mm) rims. I just think they are a more modern tyre.

Funny. I had the opposite experience fitting 32C GP5000 TR tyres to my Mavic Cosmic SLR32. It needed two of us to get the last bit over the rim. Swapped them out for Veloflex Corsa TLR 32s and they went on much easier.abatty wrote:I've found the Conti's much easier to mount and get seated - both from new and out in the field if I've needed to put a tube in (now not needed as Dynaplug works so well with big holes).

I think it's absolutely dependany on wheel/tyre combinations. I recently bought a pair of Veloflex Corsa TLR 25 and fitted them with just my hands! Needless to say they weren't tight enough and required extra layers of rim tape to seal. This is my first time fitting anything other than the IRC's previously mentioned.

Veloflex's are pretty notorious for being a loose fit. Always fitted them on with my hands on a variety of rims but as you found, seating them can be tough due to how loose they are.InSeyne wrote: ↑Wed May 31, 2023 2:11 pmI think it's absolutely dependany on wheel/tyre combinations.

Be prepared to top up the sealant regularly.
The ride quality is great though so worth the extra hassle IMO.

They are, as of now, mutually incompatible behaviors. Orange Seal lasts me ~3 months in most tires. Most of my rear tires only last 4 months anyway with my mileage. In some tires like Goodyear Eagle F1s, 40mL of Orange Seal lasts me 5-6 months…and I live in California.
Sorry Tobin but this is an blanket statement that is largely false. I stopped using Orange sealant for that reason (doesn't last long enough) and since I've started using MucOff (on my MTB and Gravel) I found the best of both worlds, seal just as good as Orange and last at least 3 times longer

I would not ride a loose fitting tire tubeless. That's a recipe for a blow off.CampagYOLO wrote: ↑Wed May 31, 2023 4:13 pmVeloflex's are pretty notorious for being a loose fit.

I found them initially tight enough, but the bead diameter stretched more than any other tubeless tire I've tried. So much that I could easily remove the tire by hand just by pulling up on the bead and peeling both sides off the rim at the same time.

Interesting - I've had very limited sucess with Dynaplugs even on relatively small ~3mm cuts. If do they hold pressure they almost always fail after a few hundred miles and I end-up having to pull the tyre and patch on the interior. Adding a second... third similarly fails.bobones wrote: ↑Tue May 30, 2023 1:48 pmThis. I would've given up on tubeless long ago if it wasn't for these guys.

I've used two packs' worth (10) now and not a single one is still in situ... i.e. I've ended up patching the tyre in all cases. There's really no scope for 'doing it wrong' on the install so I think the sealants I've used (Muck-Off and Milkit) must inhibit the bond - what do you use?
