The Surly Moonlander Fork is a steel fatbike fork built for maximum float and stability on snow, sand, and other loose terrain. Designed to fit 4.7" tires on massive 100mm rims, it features an ultra-wide 197mm spacing with a 12mm thru-axle for strength and control. The 4130 CroMoly steel construction and 50mm offset ensure confident, stable handling under load. With IS disc brake compatibility and mounts for fenders and racks, it's ready for expedition-level off-road adventures.
