Take your trail-taming abilities to the next level with the SixFifty 5500. It features a custom-formed aluminum frame with 150mm of plush rear suspension and a 150mm SR Aion fork with 35mm stanchions for responsive, predictable handling. Tubeless-ready WTB STB i35 rims paired with Kenda Regolith Pro tires combine trail-gripping traction with fast-rolling action, while the powerful Shimano hydraulic disc brakes offer precise speed control so you can rail it on the descents. An 11-speed drivetrain with Shimano SLX shifting employs a wide gear range in a compact package with tenacious chain retention so you don't have to worry about dropping a chain in the rough stuff, and a KS eTEN dropper post puts you in the best stance for speed with a quick flip of the handlebar-mounted lever.
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.
