Specialized Chisel Comp Mountain Bike
With an ultra-lightweight aluminium frame, the Specialized Chisel Comp Mountain Bike offers podium-ready performance on a budget. Advanced frame manufacturing techniques ensure the Chisel is strong, stiff, and ready to kickstart your journey into the world of cross country racing. Offering high-spec features without an astronomical price tag, the Chisel Comp leaves you with change to spare over its carbon siblings - perfect for covering race entry fees. Progressive cross country geometry keeps you in control on modern courses, offering a stable, confidence-inspiring ride.
Taking all they learned from their race-proven Epic hardtail range, Specialized developed the all-new Chisel to be their most high-tech aluminium XC frameset to date. Contemporary geometry offers a stable ride quality, with long reach measurements and a 68-degree head angle being up to task for the latest breed of cross country race tracks. Use of D'Aluisio Smartweld technology ensures it is more than ready when it comes to the rigours of racing, balancing strength, weight and rigidity across the entire size range. This allows all sizes of Chisel an equal ride character, ensuring a balanced feel no matter what size you choose.
With a frame weight as low as 1400-grams and high-quality parts specification, the Chisel Comp is the ideal companion for your journey into cross country riding. The RockShox Judy Gold fork features a Motion Control damper for compression adjustment, perfect for dialling in your ride. The latest Shimano SLX drivetrain offers premium 12-speed performance whilst keeping the price low, and their M6100 hydraulic brakes offering ample stopping power in all conditions. To provide long-lasting and creak-free performance, a threaded bottom bracket is used, making the Chisel an excellent option throughout the winter months.
