A Trail Bike Tailored for Drop Bars
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.

- Seatstay-mounted bottle bosses, plus three-pack mounts at the top and bottom of the down tube
