Why Do Racers Choose Stan's Race Day Sealant?

Stan's Race Day Tubeless Sealant is engineered for riders who need maximum puncture protection without slowing down. Its low-viscosity formula contains twice the sealing crystals of Stan's Original sealant, combining both XL and standard-sized crystals in a single formula to close larger punctures faster and more reliably than conventional sealants. When a flat could cost you a race, Race Day is the sealant you want inside your tires.

Formulated to perform in extreme conditions, Race Day remains stable and effective down to -30F, making it a dependable choice year-round regardless of climate. The 1000ml bottle provides enough sealant for multiple tires, and the fast-acting chemistry means most punctures seal before you even notice a pressure drop. Built for road, gravel, and mountain bike tubeless setups where performance and reliability are non-negotiable.

FAQ

How is Race Day different from Stan's Original sealant?

Race Day contains twice the sealing crystals of Original, including larger XL crystals that seal bigger punctures faster. The low-viscosity formula is also optimized for speed of sealing, making it the better choice when seconds matter.

How much sealant should I put in each tire?

Generally 2-3oz for road tires, 3-4oz for gravel, and 4-6oz for mountain bike tires. Wider tires and arid conditions may call for a bit more. Check sealant levels every few months and top off as needed.

Can Race Day sealant be used year-round in cold climates?

Yes. Race Day is formulated with anti-freezing agents that keep it effective down to -30F, making it a reliable choice for winter training and racing in cold conditions.

Best For

Road and gravel racers, cyclocross competitors, and XC mountain bike riders who need the highest level of puncture protection and can't afford to lose time to a flat. If you're lining up on a start line, Race Day belongs in your tires.
