Why you'll love it
- This bike wants to go fast—it's built with no-nonsense, high-performance parts
- You get a Straight Shot down tube for extra stiffness in the rough and Knock Block frame defense to protect against spinning bars and fork crowns
- TwistLoc simultaneously locks out front and rear shocks for climbs and sprints with the simple Grip Shift-like motion
- Wider Kovee Elite 30 wheels provide better tire support so you can run lower pressure and get more traction
- This short-travel trail bike gives you a suspension setup that’s capable in several MTB disciplines, and especially suited to endurance events
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.
