Best tubeless sealant for road and gravel bike tyres
Effetto Mariposa Végétalex Tubeless Sealant – 1000ml
- Plant-based biodegradable formula made with olive stones
- 3-6 month active lifespan in tyres
- Totally plastic-free option
Made in Italy from ground olive stones, Effetto Marioposa’s Végétalex Tubeless Sealant is a remarkably different offering. The semi-transparent dark green liquid couldn’t look more different to typical milky-white sealants, with plant-based fibres and particles to replace natural or synthetic latex.
Here, the finely ground stones of olives and cellulose fibres combine to create the sealing effect, held together by xanthan gum, derived from simple sugars. Effetto Mariposa claims that this combination seals punctures up to 5mm.
Besides being environmentally friendly, this formula benefits from a long lifespan in the tyre, upwards of three months and up to six months, depending on environmental conditions.
Choose from 250ml, 1L or 5L bottles, which are also supplied with a short tube to allow you to apply the sealant through the valve, should you wish. There’s also a transparent panel down the side of the bottle with graduation marks, to help you measure out the right portion for each tyre to be fitted or topped up.
