Simply put, the Evol is our dream bike in custom-butted alloy reality. Enthusiastic and aggressive, Evol’s a trail bike for enhanced fun-factor as you’re ragging it round the trails. Capable enough for racing enduro, and flattering enough that you’ll be grinning from ear to ear the whole time.
With contemporary geometry, Evol is slack, low, and long. The slack head angle inspires confidence when descending at high speeds and the low bottom bracket means you can throw it hard into every corner.
A comfortable neutral riding position, keeps your weight central so you won’t waste energy on the uphill slogs.
The top tube mounted RockShox Deluxe RT 140 mm travel shock in the rear boosts traction on the steep and technical terrain for a comfier and more playful ride. Built around new metric shock standards for increased bushing overlap, the suspension is smooth, supple, and reactive, increasing sensitivity for a playful and enthusiastic feel.

It is important to get the right size bike, if the bike fits it will be faster, more comfortable, and easier to handle. You can also take into consideration the standover height to ensure you pick a bike that will be a good fit. If you measure your inside leg and ensure there is a minimum of an inch from the toptube to your crotch this will give you enough seatpost adjustment to find your optimum saddle height.
