Surly Grappler: Your Drop-Bar Trail Conqueror

Forget limitations. The Surly Grappler redefines what a drop-bar bike can achieve on demanding terrain. Engineered with mountain bike DNA and optimized for drop-bar control, it delivers unmatched confidence whether you’re carving through rooty singletrack, exploring rugged doubletrack, or embarking on multi-day bikepacking adventures.

Built Tough for Real Adventure:

  • 100% Surly Chromoly Steel: Experience legendary durability and that signature steel ride feel with our proprietary ‘Natch tubing and double-butted main triangle.
  • Mountain Bike Geometry (Drop-Bar Optimized): Provides stable, predictable handling and a comfortable position for long days exploring dirt roads and challenging trails.
  • Versatile 27.5″ Platform: Ample clearance for grippy 27.5 x 2.8″ tires (fenders optional), conquering loose gravel, mud, and rough surfaces with ease.
  • Ultimate Hub & Drivetrain Freedom: Surly’s unique Gnot-Boost rear spacing accommodates 142mm or 148mm hubs, supporting everything from single-speed simplicity to internally geared hubs for low-maintenance touring.

Ready for Anything You Throw at It:

  • Thru-Axles Front & Rear: Boost stiffness precisely where needed for razor-sharp handling and control on technical sections.
  • Adventure-Ready Mounting: Load up with seatstay bottle bosses plus triple mounts on the down tube (top & bottom). Stealth dropper post routing keeps your cockpit clean.
  • Long-Term Resilience: Enhanced E.D. coating protects the frame inside and out, ensuring years of reliable service on backcountry expeditions or daily trail shredding.
  • Horizontal Dropouts: Simplify wheel changes and tension adjustments mid-ride.
