7/8″ S&M Old School Straight Seatpost 14″ Chrome

7/8" S&M Old School Straight Seatpost 14" Chrome

This 14-inch straight seatpost is constructed from 4130 chromoly steel with a show chrome finish. Features a knurled section for secure seat clamping and end-finished construction. Made in the USA for 7/8" (22.2mm) seat tubes.

Key Features

• 4130 chromoly steel construction – Provides high strength-to-weight ratio and flex characteristics superior to standard steel, reducing risk of bending or breaking under impact
• Knurled seat clamp area – Textured surface increases friction between post and seat for secure attachment and reduced slippage during riding
• End-finished design – Closed bottom prevents internal contamination from water, dirt, and debris that can cause corrosion or add weight
• Show chrome plating – Polished chrome finish offers corrosion resistance and classic aesthetic compared to raw or painted finishes
• 14" length – Provides extended adjustment range for taller riders or frames requiring longer post insertion depth

Compatibility and Ideal Use Cases

Designed for frames with 7/8" (22.2mm) internal seat tube diameter, commonly found on older BMX frames and some modern old-school style builds. Requires a separate seat with built-in clamp hardware (rail-style or older two-bolt designs). The 14" length suits taller riders or frames with longer seat tubes where standard-length posts don't provide adequate height adjustment. Chrome finish works for riders seeking traditional BMX aesthetics or corrosion protection in wet conditions.
