The lightest alloy full suspension mountain bike in the world. That's a bold claim, but at 18.4% lighter than the closest competitor, the Specialized Chisel mountain bike backs it up completely.
For riders who've always assumed a lightweight aluminum mountain bike meant giving up stiffness or compliance somewhere along the way, the Chisel puts that assumption to rest.
Geometry and kinematics lifted directly from Specialized's World Cup-ready Epic 8 give this bike a genuinely race-bred foundation, and you feel it the moment you lay down power on a climb.
Speed metal
The Chisel's D'Aluisio Smartweld frame is the lightest aluminum XC frameset in its class. Each tube has been extensively shaped with continuously-varied wall thicknesses, delivering stiffness where efficiency demands it and ride-smoothing compliance where the trail gets rough. It's a frame that does more with less material, and that pays off on every single ride.
Built from World Cup DNA
With 110mm of Ride Dynamics-tuned suspension, the Chisel shares its suspension kinematics directly with the Epic 8, Specialized's World Cup race machine. The result is a bike that handles varied terrain with real confidence, from tight technical singletrack to wide-open XC trails. If you've been weighing up a hardtail and wondering how much more a full suspension adds, the Chisel's answer is clear: considerably more performance, for far less weight penalty than you'd expect from an alloy full suspension mountain bike at this price.
Maximum pedalling efficiency
The Chisel is the most efficient pedalling bike in its class. A steep seat tube angle puts you in the optimal position on the pedals, and the honed anti-squat geometry keeps pedal-bob off the table on the climbs. Every watt goes where it should, straight into forward momentum.
The flex stay advantage
Rather than a traditional pivot-based rear end, the Chisel runs a flex stay design, shedding the extra weight and maintenance that come with additional pivots. More commonly seen on carbon bikes, this approach has been proven in alloy through extensive field and lab testing. You get the efficiency and light weight of a flex stay, without the carbon price tag attached.
Hydroformed precision
A one-piece hydroformed seat tube integrates the seat tube pivot, main pivot, and BB shell into a single unit. On a more traditional bike, these are separate components welded on. On the Chisel, it's cleaner, lighter, and stronger.

This Pistachio edition is also available in Specialized Chisel Red if that's more your colour. As a mountain bike for sale at this price point, nothing else in the alloy full suspension category comes close on weight or outright performance.
