Details

Big hits and all-out descents. This trail-crushing enduro machine delivers confidence and control for the rowdiest terrain. Its mixed wheel size, with a 29-inch front and 27.5-inch rear, blends stability and speed with agility that pops.

Key Performance Factors:

Race-bred suspension
Maestro rear suspension eats up enduro terrain with 165mm of smooth, active rear travel matched with a 190mm travel fork. The trunnion mount rear shock has a longer stroke (65mm over 60mm on the previous generation) while the Advanced Forged Composite upper rocker arm adds stiffness and lowers overall frame weight.

Adjustable enduro geometry
Flip chip adjustability lets you switch between two settings depending on the terrain. You can select a 63.1 or 63.5-degree head angle and corresponding 77.9 or 78.3-degree seat tube angle, resulting in a 25 or 19mm bottom bracket drop (size medium) to fine-tune handling for varying trail conditions and riding style.

Mixed wheel size
A 29-inch front wheel provides speed, stability and front-end control on rough, technical trails. A 27.5-inch rear wheel adds agility and maneuverability to help riders rail corners, pop over features and show off their style.
