Promax Seat Post 33.9 MM

Description

Description

The Promax Seat Post is a robust, reliable, and performance-oriented rigid seat post designed for a wide variety of cycling disciplines, often used for upgrades on mountain bikes, road bikes, and hybrid/commuter bikes.

Here is a detailed description of its key features and specifications:

Key Features

• Construction Material: It is made from lightweight, high-strength 2014 aluminum alloy tubing. This material provides an excellent balance of durability, fatigue resistance, and weight savings.
• Head Design: The head (where the saddle clamps) is cold-forged aluminum alloy. Cold-forging is a process that compacts the metal structure, resulting in a stronger and more reliable part than simple casting.
• Clamp System: It utilizes a secure and highly adjustable two-bolt clamp design. This mechanism ensures the saddle rails are held firmly, preventing slippage, and allows for precise micro-adjustments of the saddle’s tilt angle (up to 26 degrees) and fore/aft position.
• Offset/Setback: The SP-1 features a 20mm offset (or setback), meaning the center of the clamp sits 20mm behind the center line of the post tube. This provides a more traditional riding position and can help riders fine-tune their fit and balance over the pedals.

The Promax SP-1 Seat post is a robust, reliable, and performance-oriented rigid seat post designed for a wide variety of cycling disciplines, often used for upgrades on mountain bikes, road bikes, and hybrid/commuter bikes.¹

The Promax SP-1 is a popular choice for cyclists who need a dependable, fixed (non-suspension) seat post that offers excellent stiffness, good adjustability, and a favorable strength-to-weight ratio without an excessive price tag. It is a solid, tried-and-true component that meets or exceeds general cycling standards (like ENM).
