What Is It?
The Sludge Presta Version 100 is a 100ml anti-puncture tyre sealant specifically designed for road bikes using Presta valves. It uses microfibres that allow the sealant to pass through narrow Presta valve systems while helping seal small punctures automatically during riding.

- Microfibre sealant formula for easier valve flow
- Helps seal small punctures and thorn holes
- Suitable for high-pressure road tyres
