What is my size?

Share

From the bike part to enduro tracks to steep singletrack shredding, this all-mountain bruiser has swagger to spare. The lightweight, super-stiff aluminum frame is long and low, and its Maestro suspension helps you float through the rough stuff.

This amped up version of the Reign enduro and all-mountain machine is made for riders who gravitate toward steep, rough and aggressive descents. It offers a longer travel 180mm fork and robust components that make it suitable for unforgiving terrain. The super strong and stiff ALUXX SL aluminum frame features updated geometry with a longer cockpit that’s designed to optimize its 27.5 wheels. The trunnion-mount Maestro rear suspension system offers 160mm of smooth, active travel and is bolstered by the new Advanced Forged Composite upper rocker arm, which is lighter and stronger than the previous aluminum design. If hammering through rock gardens and flying down steep descents is your idea of the perfect ride, then Reign SX is the machine for you.

Key Performance Factors

27.5 agility and control

27.5-inch wheels balance agility and control, giving you the ability to roll over rugged terrain, flick the bike at speed, change lines, and explode out of corners.

Latest suspension tech

Updated Maestro rear suspension features a trunnion mount shock with a longer stroke and smoother feel. With 160mm of travel (and 170mm up front), it has the new Advanced Forged Composite upper rocker arm for increased stiffness and strength plus lower overall frame weight.

Enduro geometry

The lightweight and stiff Advanced-grade composite frameset features updated enduro-style geometry, so you can ride aggressive descents and rail corners with confidence.

WeightThe most accurate way to determine any bike’s weight is to have your local dealer weigh it for you. Many brands strive to list the lowest possible weight, but in reality weight can vary based on size, finish, hardware and accessories.
