The Specialized Chisel frameset makes a bold claim: the lightest, fastest alloy full suspension frameset in the world.
And the numbers back it up, sitting 18.4% lighter than the closest competitor, with geometry and suspension kinematics pulled directly from the Epic 8, Specialized's World Cup XC race machine.
That connection to the Epic 8 isn't just marketing lineage. The Specialized Chisel FS frameset shares the same Ride Dynamics-tuned suspension philosophy, the same progressive geometry refined on technical World Cup courses, and the same approach to anti-squat that keeps pedalling efficient when the trail gets rough.
Whether you're racing or just pushing hard on a familiar loop, you feel it immediately in how little energy gets lost between the pedals and the ground.
The frame itself is built around D'Aluisio Smartweld hydroformed tubes with continuously varied wall thicknesses, stiff where stiffness helps and compliant where compliance counts.
The one-piece hydroformed seat tube integrates the seat tube pivot, main pivot, and BB shell into a single structure, cutting weight and complexity at the same time.
The flex stay rear end is worth understanding properly. Most alloy bikes can't make it work, but extensive lab and field testing on the Chisel FS frame shows it achieves the same efficiency and weight savings you'd expect from a carbon flex stay design. No extra pivots, no extra maintenance, just a cleaner, lighter rear end.
Key specs on the Specialized Chisel frame:
- D'Aluisio Smartweld hydroformed tubes with engineered junctions throughout
- 110mm travel with flip chip geometry adjustment
- Ride Dynamics-tuned RockShox Deluxe Select+ rear shock
Available in Mauve/Oasis over Silver, the Specialized Chisel frameset is the one to build up if you want XC race performance in alloy, without compromise.
