The Trail Grinder is a rocket of a gravel bike. With its swanky, 2.10-inch Schwalbe Thunder Burt tires, a Kind Shock dropper seatpost, and a SRAM Apex 1x drivetrain, the Trail Grinder lets you know where it wants to go.
Built around a lightweight aluminum frame and carbon fork combo, the Trail Grinder is an agile ride that'll drive you to test your limits. Tubeless-ready rims enable a low-cost upgrade to improved traction and flat protection. Excellent components throughout, including a Selle Royal Asphalt saddle, leave little else to be desired.
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.
