5 / 5

Practical and effective

- Casper, 21 September, 2025

Apart from the fact that this brand of sealant just seals very well, the bottle is also practical for road bikes. The nozzle is suitable for refilling via the valve and the amount in the bottle is enough to provide both tyres with new sealant.

Pros & Cons

Easy refilling via valve
Seals holes effectively
Volume compatible with road bikes

Easy to refill. No leaks yet.

- Stefan, 10 July, 2025

Been driving it for a few months now and have not had a flat yet. I especially like the fact that it is very easy to refill tyres through the valve. A pity there is no dispensing bottle with the 1 litre version, but fortunately I still had one.

Pros & Cons

Easy to refill
Environmentally friendly
No dosing bottle with 1 litre bottle

Seals holes well and fills via valve

- Stefan, 23 August, 2024

Does what it needs to do. Had 2 holes that were quickly plugged. Also an advantage that you can fill through the valve. With my old Stan's Tube you couldn't because of the thick lumps

Pros & Cons

Fill via valve

Effective, environmentally-friendly product, but packaging could be improved

- Cédric, 15 February, 2024

The product is perfect. It does the job and seals holes even in wet conditions. It's claimed to be biodegradable, which is a plus in my book. I was impressed by the thin tip. It fits easily into a presta valve (without the obus) or between the rim and the tubeless tyre, just a little apart. Unfortunately it's fragile and broke on the 2nd use :( So the container isn't really reusable if you buy a larger volume of liquid.
