This mountain is yours. Whether you rooster the loam or fly loose over the rock gardens, the top-shelf Copperhead EVO AM 4, with its 150mm Rockshox Lyric front fork and rear Deluxe Select, will smooth it out for you and stick you to the trail. And, this Ripper makes uphills as fun as the descents all day long with the all-new Bosch Gen4 CX motor and 625Wh Powertube battery. DT Swiss H1900 rims round out this ride with 12-speed Shimano XTR groupset and 203mm Shimano brakes front and rear. AND, you can push the limits of sunlight with BULLS' standard Monkey Link Connect*.

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.
