Details

Designed to go where no normal fat bike can, the Surly Moonlander is for riders who want otherworldly capabilities on rocky shorelines, sand, snow, and desolate landscapes not yet discovered. While our proprietary 24 x 6.25” tires surpass the limitations of current fat bikes, the Moonlander still rides like a normal bike, making it easier (and more fun) to navigate previously unrideable terrain. It’s the ultimate choice for explorers who itch for the next great adventure, and aren’t afraid of what they might find.

- Constructed from 100% Surly Chromoly Steel for excellent durability
- Surly's first bike with a 9-speed Pinion gearbox, an innovative approach to spur gearing that improves reliability and go-anywhere performance with less maintenance
- Large volume Surly Molenda Tires on 24 x 100mm Surly Clown Royal Rims creates footprint large enough to float over unpredictable terrain
- Clearance for 24 x 6.25” tires, as well as 26 x 5.1”, 27.5 x 4.8”, and 29 x 3”
- Comes with rack and fender mounts, as well as accessory mounts on both fork blades to enhance cargo capacity
- Weight distribution across front and rear, with a longer back, allows for greater stability
- Features TEKTRO HD-M285 Hydraulic Disc Brake System
- Four frame sizes to fit most riders: SM, MD, LG, XL
- Includes a dropper for easier on and off, especially on soft surfaces"
