S&M Long Johnson Pivotal Seat Post 25.4mm & 27.2mm

The S&M Long Johnson is a 320mm pivotal seat post available in both 25.4mm and 27.2mm diameters, covering standard BMX frames as well as race frames that require the wider 27.2mm size. The 320mm length provides a wide range of height adjustment from slammed low to full riding height without compromising safe insertion depth.

Key Features

• 320mm length — Longer than standard pivotal posts, providing enough adjustment range to run the seat at full riding height or slammed low without compromising safe minimum insertion depth
• Available in two diameters — 25.4mm suits the majority of standard BMX frames; 27.2mm accommodates race frames and any other frame requiring the wider seat tube diameter — confirm your frame's seat tube inner diameter before ordering
• Compatible with all pivotal seats — Standard pivotal interface works with any pivotal seat regardless of brand
• Laser etched Sharpie Shield logos — Branding is laser etched directly into the post rather than using decals, providing a durable finish that will not peel or fade with use

Compatibility and Ideal Use Cases
