The Ghost 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, 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.

Cleared for girthy tires and decorated with an array of mounts for hauling your daily provisions and overnight gear, the Ghost Grappler is ready to take you and your paraphernalia down that overgrown fire road for an extrasensory experience. There’s nothing to be afraid of. Probably.
