The bike's geometry is influenced by the World Cup-winning Epic series, ensuring top-tier handling and control.

The RockShox Recon Silver RL fork provides 120mm of smooth travel, perfect for absorbing bumps and maintaining speed over rough terrain. The SRAM NX Eagle 12-speed drivetrain offers a wide range of gears, allowing for quick shifts and efficient power transfer on climbs and descents.

Braking is confident and controlled with SRAM Level T hydraulic disc brakes, ensuring you can tackle technical descents with ease. The 29" wheels with Specialized Ground Control and Fast Trak tyres provide excellent grip and stability, ensuring you stay connected to the trail.

The inclusion of a TranzX dropper post means you can adjust your saddle height on the fly, giving you the flexibility to handle varied terrain without missing a beat. Whether you're competing in a race or enjoying a solo adventure, the Specialized Chisel Base is ready to take on the challenge.

For those looking to spread the cost, the Chisel Base is available with 0% APR finance, making it easier to get out on the trails sooner.
