The Grappler is Surly's dedicated drop-bar trail bike. With mountain geo designed around a comfortable, confident drop-bar hand position, it's lively and responsive on single track, double track, and other degraded surfaces. Ready to haul essential gear for all-day dirt rides and quick bikepacking excursions, captured thru-axles front and rear provide ideal stiffness and handling. Built around 27.5" wheels and compatible with internally geared hub and single-speed setups, Surly's tried-and-true Gnot-Boost spacing allows riders to run 142mm or 148mm rear hubs.
