Technology that sets the pace.

For riders who want to unlock the full potential of modern XC.

The Author Magnum is a high-performance carbon hardtail built for modern cross-country riding. It combines an ultra-lightweight frame, race-focused geometry and the latest technologies to ensure every pedal stroke delivers instant acceleration and maximum efficiency.

At its core is a lightweight AUTHOR High Modulus Toray T800 carbon frame, offering exceptional stiffness while keeping weight to a minimum. Every bit of energy is transferred directly into forward motion – exactly what you expect from a fast XC machine.
Control on demanding terrain is handled by the Rock Shox SID SEL+ Remote 29 AIR suspension fork with handlebar lockout.
Allows the rider to instantly switch between maximum efficiency on climbs and enhanced comfort in technical sections.
Magnum pushes modern XC even further with SHIMANO Deore XT Di2 electronic shifting (12-speed), delivering extremely fast, precise and consistent gear changes under any load.
The build is completed with lightweight AUTHOR Flyer Carbon 30 wheels and an integrated AUTHOR carbon handlebar and stem combo, reducing weight while creating a clean, race-ready cockpit.

The result is a mountain bike ready for race pace, long-distance marathons and fast, performance-driven rides.
