The Growler Double Stout Carbon represents a new way of thinking about how a fat bike performs on a trail.  This sub 30lbs full carbon fiber full suspension fat bike combines 120mm travel with a 27.5x4" tire to give the Growler Double Stout 27.5 Carbon the handling and control required for challenging multi seasonal adventures. Think of it as a "do-anything" fat bike with real world trail capabilities.

Rockshox Monarch XX

Few things would piss off Newton more than the Monarch XX. Simply put, no other shock packs more energy-efficient performance in a lighter weight package – one that seemingly defies Newton’s so-called "laws" of physics. But the Monarch XX does exactly that, providing the ability to lock-out rear suspension via a single bar-mounted XLoc Sprint button.

The 100% hydraulic remote lever and system is completely sealed, so unlike cable-actuated units – Monarch XX is impervious to contamination. If Newton were alive today, we doubt he'd be that stoked to go back to the drawing board with his theories. But a few miles on the Monarch XX sure would help inspire a new way of thinking, and riding.
