Pros & Cons
Pros & Cons
- Easily convert your tyres to tubeless with this sealant.
- The aeropolymer seals tyre punctures up to an impressive 7.5 mm in diameter.
- This sealant doesn't dry out for at least 8 months, so you won't have to top it up as quickly.
- This sealant won't damage your wheel or your rims.
- Sealant has to be topped up every 3-6 months to guarantee its reliability, so buying in bulk might not be a bad idea.
- You'll need a specialised valve, tyres and tubeless ready wheels to be able to ride tubeless.

Effectively seals punctures!
This sealant is designed to effortlessly seal punctures with a diameter up to 7.5 mm. Ride outside without flats, even in winter. Plus, this sealant is designed not to damage carbon, aluminium or rubber products, so you can be sure your wheelset and tyres won't be damaged. To top it all off, this sealant is compatible with CO2 cartridges, so you can use these if you should still get a flat tyre.
Durable repair
The mantel Bio Tyre Sealant contains an aeropolymer, a fibre-shaped polymer with a very low density that closes seals. Thanks to this polymer's fibre structure, it ensures a long-term, reliable seal!

Reliable product at a good price
Good purchase. I have only been riding tubeless for 1.5 years. This is the 3rd brand I am testing and am definitely satisfied. Rode more than 2000 km on it in the meantime. The sealant works well: good seal at holes, bike frame does not get sprayed much if at all. For me it worked much better than the Continental Revo Sealant. I ride on 32mm-rac tyres at 3.5 to 4.0 bar. No real downsides to give. Only, I confirm that it is difficult to modulate with a 1l bottle. Nothing insurmountable. I poured this over into Continental's smaller bottle. Could also be done with a 20 or 50ml syringe. To be bought at the drugstore or pharmacy for a few EUR. It's on my list because it will probably be easier to refill via valve. I will test some other brands, but this one is fine.

Sealt a mountain costs a bit!
I had this sealant during the AGR tour, apparently punctured somewhere but didn't notice anything. The sealant did its job perfectly

better occasionally pay more expensively for an "A" brand
To my regret, I thought I had made a bargain. Unfortunately, it had failed to seal the small hole in my tyre. So in the end there was sealant everywhere on the down tube of my frame, mixed with the dust.... And I could scrape and scrub it off afterwards.
