DUO Brand Stun 1 20" Tire

Product Overview

The DUO Brand Stun 1 20" Tire is a modernized all-purpose clincher built on the proven Stunner design. The 2.35" sizing delivers a larger contact patch and rolling diameter compared to the original. Upgraded tread pattern withstands bigger impacts and meets contemporary riding demands. Suitable for street, park, and freestyle applications.

Key Features

• Stunner design foundation – Built on the proven original Stunner geometry refined by pro riders Chris Doyle and Van Homan. Established design with real-world validation across decades of professional and amateur riding.

• Modernized tread pattern – Upgraded from the original Stunner to withstand larger impacts and increased demands of contemporary riding. Enhanced durability without sacrificing grip or responsiveness.

• 2.35" sizing (2.36" inflated width) – Larger than original Stunner profile, providing bigger contact patch for increased grip and stability. Wider tire accommodates modern BMX geometry and rider preferences without excess weight.

• 21.2" inflated diameter (538mm) – Slightly larger rolling diameter increases top speed marginally and provides additional cushioning on impacts compared to lower-profile tires.

• 60mm inflated width (2.36") – Wide profile delivers substantial contact patch for lock-ins, slides, and technical maneuvers. Provides confidence on street and park surfaces without sluggish feel.

• 65 psi maximum pressure – Moderate pressure rating allows customization across a useful range. Higher pressures (50–65 psi) favor responsive feel and minimal rolling resistance; lower pressures (40–50 psi) increase grip and marginal cushioning.

• Clincher construction – Standard hook bead design fits any 20" BMX rim with clincher seat. Simple, proven technology with reliable tire seating and no special rim requirements.

• All-purpose performance – Versatile tread and compound suitable for street, park, and freestyle riding without specialized surface focus. Balanced design accommodates varied terrain and trick applications.

• 23.25 oz weight – Light enough for responsive trick performance while providing adequate material for durability. Balanced weight maintains acceleration without sacrificing grip or longevity.
