Specialized Chisel 2025

METALLICLY FAST: Thanks to D’Aluisio Smartweld, the Chisel is the lightest XC aluminum frame in its class.
Each highly manipulated frame tube features a continuous variation in wall thickness and a shape that provides rigidity where you need it, for greater efficiency, and smoothness where you want it, for greater comfort and optimal control. UNLIMITED CAPACITY: With 110mm of suspension with our Ride Dynamics technology, the Chisel’s high-performance pedigree can be traced directly back to the Epic 8, our World Cup racing machine.
The Epic 8’s advanced suspension kinematics DNA, Ride Dynamics suspension and progressive geometry honed on technical World Cup circuits are found in the Chisel, making it more than capable of handling varied terrain with confidence and speed. INCREDIBLY EFFICIENT: The Chisel is the most efficient lung bike in its class, taking advantage of the geometry and kinematics used in our multi-World Cup-winning Epic 8 platform.
The inclined seat tube puts the rider in the optimal pedaling position.
The sharp anti-squat reduces “false pedaling”.
All of this makes the Chisel translate every watt applied to the pedals into maximum forward motion. SMOOTHER IS FASTER: We’ve designed a flexible seatstay rear end for class-leading suspension performance, while eliminating the added weight and maintenance associated with the pivots required in a traditional design.
More common in carbon bikes, extensive field and laboratory tests prove that Chisel has achieved the impossible: the efficiency, control and lightness of a flexible seatstay design in advanced aluminium. HYDROFORMED ALUMINUM: The Chisel saves material and weight with a one-piece hydroformed seat tube that integrates the seat tube pivot, main pivot and bottom bracket box.
On a more traditional bike, the seat tube is usually just a “tube” with the pivots and bottom bracket welded together.
