Ghost Grappler is a drop-bar trail bike built for single-track sessions, all-day dirt rides, and bike packing excursions.
Off-road enthusiasts have been Frankensteining drop bars onto trail bikes for decades, so we designed the Ghost Grappler to scratch that itch with a little more precision. Engineered first and foremost around a stable and comfortable drop-bar hand position, its trail-ready geo provides a spirited ride on mixed terrain.
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.

 Different tire and rim combinations will result in different clearances.  Depending on drivetrain configuration, tire clearance may be limited by the chain and not the frame.  Listed chainring clearance is worst case scenario. Clearances vary widely depending on components and configurations.
