Why you'll love it
- This bike is light, fast, and capable of shredding any kind of trail whether you’re heading out for an afternoon session or miles of endurance riding
- RE:aktiv with Thru Shaft works faster than a normal shock, so it tracks the ground better and keeps you in control
- A sleek internal storage compartment gives you a versatile spot to stow tools and gear
- We expanded our size range to ensure a better fit for all riders. And, you get the fastest wheel that fits your frame: XS frames get 27.5-inch wheels, S frames get to choose between 27.5-inch or 29-inch, and sizes M to XL get 29-inch wheels
- Make it yours: it's customizable through Project One
Smaller frames (XS and S) have a top tube that dips down as it approaches the seat tube. This design makes for a lower standover height, which is good for shorter riders because it allows them to straddle their bike more easily. Larger frames (M and up) have a straight top tube because taller riders with longer legs typically don’t have the same issues with standover height.
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.
