Will this work?

- Single-bolt micro-adjust clamp — fore/aft and tilt
- Standard 7x7mm rail clamp
- 360g — alloy, road/MTB universal
- Fits any frame with a 31.6mm seat tube ID
Condition: Excellent. Light signs of use — surface shows minimal wear consistent with normal installation. Clamp hardware clean and functional. No scratches, dents, or damage noted.
Notes from MyBikeThing: Fuji’s OEM alloy posts are built to spec for their own bikes — that means proper tolerances, good clamp hardware, and reliable single-bolt adjustment. 31.6mm is the most common oversized post diameter on modern alloy road and MTB frames, making this an easy drop-in replacement or upgrade. Excellent condition means there’s nothing to overcome here — just install and ride.
Workshop Wisdom: Always apply a light coat of grease to the insertion section of an alloy post in an alloy frame before installing. It prevents galvanic corrosion that can seize the post permanently in the seat tube. If using in a carbon frame, use carbon assembly paste instead — no grease.
Guarantee: You put in the miles, we put in the work! 30-day Guarantee, rest assured of fit, function and condition. 🙂
