Surly Grappler

The Grappler is built for stability and comfort on rough terrain rather than pure speed. Its geometry is optimized for trail handling and long-distance bikepacking, making it a better choice for loaded adventures and technical singletrack than for competitive gravel racing.

The frame clearance accommodates tires up to 27.5 x 3.0 inches. It comes stock with 27.5 x 2.5-inch tires, giving you plenty of room to size up if you want extra cushion and traction for looser surfaces.

Yes. Thanks to Surly’s Gnot-Boost spacing and custom dropouts, the frame is compatible with single-speed setups, as well as internally geared hubs, giving you significant flexibility to customize your drivetrain.

The Gnot-Boost spacing allows the frame to accept both 142mm and Boost 148mm rear hubs. This versatility makes it easier to swap wheels or upgrade your drivetrain without being locked into a single hub standard.

Absolutely. The frame is designed with bikepacking in mind, featuring three-pack mounts on the down tube and seatstay-mounted bottle bosses. You have ample options for attaching cages, bags, and racks to carry your gear securely.

The 100% Chromoly steel frame is heavier than carbon or aluminum, but it offers a distinct advantage in durability and ride quality. It provides a naturally compliant, vibration-damping feel that excels on long, rugged rides where comfort is a priority.
