Parkside is a high-performance ammonia free tubeless tire sealant designed for mountain, gravel, cross-country, and road.
We are a small company rooted in Lake Forest, California, and have a team of test riders across the country in states including California, Oregon, Utah, Arizona, Minnesota, Tennessee, and Florida.
Our primary objective is to provide a premium tubeless tire sealant that performs exceptionally well under demanding riding conditions.
Our proprietary formula of fibers and micro-solids interlock and plug punctures up to 6.5 mm.
Through extensive research and testing, we are confident Parkside will outperform any of the major brand sealants available on the market.
For optimal performance, we recommend visually inspecting the sealant in your tires every 7 to 12 weeks to monitor liquid levels.
Key features of our sealant include:
- It does not ball up.
- It effectively prevents sidewall leakage.
- It contains no ammonia.
- It is non-corrosive, non-toxic, and non-hazardous, making it safe for both carbon and aluminum components.
Our sealant is compatible with all types of tubeless tires, including downhill, all-mountain, cross-country, gravel, and road tires.
