27.2 Internal Seat Binder K26058

The Cannondale 27.2 Internal Seat Binder K26058 is an original replacement wedge kit built for Cannondale F-Si frames. It secures a 27.2mm seatpost through an internal binder mechanism, keeping the post firmly clamped inside the seat tube. This kit includes both the wedge and binder components needed for a complete replacement.

This binder wedge kit suits riders replacing a worn or damaged original unit on their F-Si frame. Proper installation restores secure seatpost clamping and consistent saddle height retention on the trail. As a direct-fit part, it matches Cannondale's factory specification, making it a straightforward swap for anyone maintaining their F-Si mountain bike.
