Grappler – Purple Dust Bunny
Bikepacking / Singletrack / Fire Roads
A Trail Bike Tailored for Drop Bars

The Grappler was born from a long tradition of riders adapting trail bikes for drop-bar adventures. Surly engineered it from the ground up with a geometry that prioritizes comfort and control from the drops—without compromising trail performance.

Designed to be confident on fire roads, singletrack, and wherever else curiosity leads, the Grappler comes equipped with generous tire clearance and a full suite of mounting points to haul all your essentials. Whether you're planning a week-long bikepacking trip or a post-work dirt detour, this drop-bar trail bike is ready to take you there.
