SPECIALIZED STUMPJUMPER ALLOY 2022

The Specialized Stumpjumper Alloy is a modern and versatile trail bike that brings the key features of the new Stumpjumper generation to a fully aluminum frame, which is lightweight yet extremely durable. Designed to tackle any trail with confidence and fun, it combines updated geometry, efficient suspension, and a simple, reliable drivetrain.

The asymmetric design alloy frame provides rigidity, durability, and predictable handling on the trails. The suspension kinematics, developed based on experience gained with the Enduro and tested for OLTRE 1,000 hours, ensures pedaling efficiency and great descending capability. The increased anti-squat reduces bob during pedaling, while the response to sharp impacts improves control on technical terrain.

Progressive S-Sizing geometry ensures stability and handling: the long and low frame, slack head angle, reduced-offset fork, and more vertical seat tube improve riding position and trail confidence. The Flip Chip system allows you to adjust the bike's geometry to suit your riding style or the type of trail.

The 12-speed SRAM SX Eagle drivetrain offers a wide and intuitive gear range, ideal for tackling steep climbs and fast sections. The RockShox and X-Fusion suspension, along with hydraulic disc brakes and Specialized Butcher and Purgatory tires, complete a setup ready for any trail adventure.

Tip: to receive the bike ready to ride, you can add the “Bike assembled and adjusted by Cicli Drigani technicians” option to your cart for €59. With this service, the bike will arrive assembled, adjusted, and ready to pedal. Without this option, the bike will be delivered in the manufacturer's original packaging and will require some technical operations before it can be used safely.
