Big hits and all-out descents. This trail-crushing enduro machine features a unique paint treatment that makes each bike one of a kind. Its mixed wheel size, with a 29-inch front and 27.5-inch rear, blends stability and speed with agility that pops. The geometry is designed for a longer-travel 165mm rear suspension setup and a 180mm fork, giving you the upper hand on the on the rowdiest trails and bike park terrain.

Key Performance Factors

RACE-BRED SUSPENSION

The Maestro rear suspension eats up enduro terrain with 165mm of smooth, active rear travel matched with a 180mm travel fork. The trunnion mount rear shock has a longer stroke while the Advanced Forged Composite upper rocker arm adds stiffness and lowers overall frame weight.

ADJUSTABLE ENDURO GEOMETRY

A flip chip feature lets you adjust frame geometry depending on the terrain. You can select a 62.6 or 63-degree head angle and corresponding 77.4 or 77.8-degree seat tube angle, resulting in a 20 or 15mm 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.

Highlights

This gravity-focused enduro machine features a lightweight, stiff and super-strong ALUXX SL frameset with a unique paint treatment that makes each bike one of a kind. The geometry is updated to provide added suspension travel in the rear (165mm) along with a 180mm fork to take on the roughest trail conditions. You can adjust the geometry with a flip chip that lets you switch the head tube and seat tube angles, along with bottom bracket drop, to dial in the handling for your riding style and terrain. And a new integrated down tube storage feature provides convenient carrying capacity for on-trail essentials.

    The 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. All our bikes are designed for best-in-class weight and ride quality.
