The Origin8 Pro Fit seatpost is a durable, extra-long alloy post built for riders who need maximum insertion depth and precise saddle adjustment. The zero-setback design keeps the saddle directly over the seat tube, which is helpful for fit corrections or more upright riding positions.
This post is well suited for commuters, mountain bikes, and taller riders who need additional post length without moving to a dropper.
Key Features
• Forged AL6061-T6 aluminum construction
• Extra-long 400mm length for extended insertion
• Zero-setback design for forward saddle positioning
• Two-bolt micro-adjust hinged clamp
• Designed for strength and repeatable adjustment
Compatibility & Use Notes
• Seatpost diameter: 31.6mm
• Length: 400mm

Service / Ownership Context
Two-bolt clamps offer better saddle angle control but require even tightening on both bolts. Use assembly compound appropriate to your frame material and confirm minimum insertion marks are respected. Recheck torque after initial rides.
Fit & Use Signals
• Your frame uses a 31.6mm seatpost
• You need extra post length for fit or frame size
• You want zero setback for a more forward position
