The ride of the Six50 EVO AM 1 is so natural, so a part of you, we've nicknamed it Shadow. (Also, partly due to it's blacked-out frame and wheelset). This Bosch-powered black beauty has the muscle for the uphills and the limber tendons of the 150mm front and rear BULLS Lytro and SR Suntour suspension. And, with 180mm rotors and Shimano BR-MT200 hydraulic disc brakes, it ensures you stay in control. Rounding out the build is a reliable Shimano Deore 1x10 drivetrain, a Kind dropper post for gnarly descents, and a set of Schwalbe Smart Sam tires that blend traction and speed.

Plus-size rims and tires

Wider than standard yet narrower than fat, plus-size rims and tires hit the sweet spot in grip, stability, and speed, giving you more confidence on technical terrain. Compared to a standard tire you’ll feel grip in places you wouldn’t expect thanks to a bigger contact patch and greater rollover clearance. More air volume allows lower tire pressures which softens bumps and increases float on sand or snow. Whether you’re a novice or an expert, the benefits of plus-size tires and rims will amplify your mountain biking fun.

Dropper posts

A dropper seatpost allows you to quickly lower and raise your seat to give you an ideal riding position. Dropping your seat creates a lower center of gravity for better control and maneuverability on steep descents, while raising it puts you at normal riding height for efficient pedaling.

Construction can include either hydraulic- or cable-actuated systems and the post’s travel can either be infinitely adjustable or stopped at set intervals, depending on the model.

Dropper seatposts come in standard lengths and diameters and vary by the amount of travel.
