DUO Brand Stealth Pivotal Seat Post

Product Overview

The DUO Brand Stealth Pivotal Seat Post is a lightweight aluminum seat post designed for BMX bikes using pivotal seat systems. Available in two diameters and two lengths, it accommodates various frame sizes and rider preferences. The 1-piece forged construction delivers strength and minimal weight for street, park, and freestyle riding.

Key Features

• 6061 forged aluminum construction – Single-piece design eliminates welded joints, reducing potential failure points and weight. Forging process increases material density and strength compared to cast or machined alternatives, improving durability under impact and flex.

• 1-piece design – No welds or multi-part assembly means consistent structural integrity throughout the post. Simplifies replacement and reduces assembly variables that can affect seat stability.

• Dual diameter compatibility (25.4mm, 27.2mm) – Fits both standard and oversize BMX seat tubes. Choose based on your frame's internal seat tube specification.

• Two length options (200mm, 330mm) – 200mm suits frames with integrated seat stays or higher seat tube entry points. 330mm accommodates longer seat tube lengths and riders preferring greater seat post extension.

• Pivotal and Stealth Pivotal compatibility – Works with both standard pivotal seats and Stealth Pivotal seats (recessed mounting). Verify your seat type before ordering to ensure proper fit.

• Minimal weight at 4.5 oz – Low mass reduces rotational inertia and pedaling load, improving trick responsiveness and maneuverability during line setup.
