Product Details
FUNN Crossfire Seatpost 31.6X400mm
The FUNN Crossfire Seatpost is a lightweight and durable option for riders who prefer the reliability of a fixed seatpost. Designed for those who don’t need a dropper post but still want a high-quality component, the Crossfire delivers dependable performance and clean styling for modern bike setups.
Constructed from 3D forged AL6061 aluminium, the seatpost provides excellent strength while keeping weight low. Its bead-blasted finish gives it a tough, refined look while helping resist everyday wear from trail and off-road riding.
The twin-bolt saddle clamp design offers a strong and secure hold while allowing precise saddle adjustment. This makes it easy to dial in the perfect riding position for comfort and control.
With a 31.6mm diameter and 400mm length, the Crossfire seatpost fits many modern mountain bike frames requiring a 31.6mm seatpost.
Key Features:
- 31.6mm diameter / 400mm length seatpost
- 3D forged AL6061 aluminium construction for strength and durability
- Lightweight design with tough bead-blasted finish
- Twin-bolt saddle clamp for secure hold and precise adjustment
