When we find ourselves with a deep, primal urge to explore beyond the horizons of our beloved Flat Earth, few things satiate this need. Moonlander is one of them. A portal into previously unridden terrain, Moonlander goes where other fat bikes don’t dare, where traction is a supposed myth and the only grams worth saving are in our Dugout Bag. Our newly developed, high-volume Molenda tires were key. (Even the fattest in-market tires don’t cut it, and that includes our own line.) Therefore, we equipped this one with 24 x 6.2-inch tires on 100mm rims. Such a large footprint allows us to ride at very low pressure, enabling the ability to float over a geographic smorgasbord of otherworldly terrain. Think rocky dunes, creeping shorelines, frozen beaches, sinuous stretches of snow and the like. Carefully crafted from our 4130 Chromoly steel, with a bottom bracket height that supplies plenty of clearance for bushwhacking and monster-trucking without losing out on stability 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 The top tube maximizes standover height and foot dabs into soft substances, while keeping the headtube high so you can set up your rig in a comfortable, all-day-grind riding position Large volume Surly Molenda Tires on 24 x 100mm Surly Clown Royal Rims inflated by new TPU tubes creates a footprint large enough to float over unrideable (until now) terrain Clearance for 24 x 6.2” 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 (compatible with our rear disc wide rack) 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 Frameset Frame Surly Moonlander Frame - 100% Surly Chromoly steel.
