The Pivot Firebird's 1.5-inch head tube and dw-link suspension.
The Firebird's massive 1.5-inch head tube (left) adds huge amounts of front end stiffness and is compatible with Cane Creek's AngleSet headset (sold separately), which lets you dial in the head angle. Plus, you can run any size fork steerer. The image on the right shows the impressive dw-link rear suspension and floating shock. The Firebird utilizes a short, flex-free lower link with a super-stiff carbon upper link for precise rear-end tracking.
