Reviews over the

Mantel Bio Tyre Sealant

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.

Pros & Cons

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

Pros & Cons

Easy to use and highly effective

Have long looked forward to making tyres tubeless but it was very easy

Pros & Cons

I have been using the sealant for 2 months now, in that time I punctured once without realising it. The sealant sealed the hole and only at home did I see the blue splashes on my bike. After 2 months I changed MTB tyres. All the sealant was still liquid then. So it seems to work very well!

Pros & Cons

Quality of service In the absence of testing products
