FSA Energy Seatpost 27.2mm x 350mm – 20mm Setback – Black

The FSA Energy seatpost is a lighter, more refined alloy post for riders who want strength, clean looks, and compatibility with modern electronic drivetrains. It uses a 6066 aluminum shaft with shaping focused on stiffness where it matters and reduced weight where it doesn’t.

This is a good fit for road and gravel bikes where precise saddle adjustment, electronic shifting compatibility, and a balanced ride feel are priorities.

Key Features
• 3D forged and CNC machined AL6066 construction
• Directional butting for stiffness and weight reduction
• 20mm setback for improved fit options
• Saddle clamp supports standard and oval rails
• Clean internal design compatible with electronic routing

Compatibility & Use Notes
• Seatpost diameter: 27.2mm
• Length: 350mm
• Setback: 20mm
• Compatible with 7mm round rails and 7x9mm oval rails
• Compatible with Di2 and WE electronic shifting systems
• Not compatible with frames requiring a different seatpost diameter
• Not designed for dropper-post use

Service / Ownership Context
This post requires proper torque and correct rail hardware orientation, especially when used with oval carbon rails. Use carbon assembly paste if recommended by the frame manufacturer, and always recheck saddle clamp torque after initial rides.

Fit & Use Signals
• Your frame requires a 27.2mm seatpost
• You want a lighter alloy post with setback
• You run or plan to run electronic shifting
• Not a fit if your frame uses a different diameter
• Not a fit if you need a dropper or zero-setback post
