Surly Moonlander – Lunar Dust
Overview
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.

Well, Surly has definitely done it this time: no need for fancy suspension bits where we’re headed! This Cro-mo rigid monster has 24 x 6.25″ tires AND a 9 speed Pinion gearbox, so you can have gears without rubbing your chain on the tire while climbing! It has a dropper for the techy descents, and an oh-so-comfortable Terminal Bar, and is covered in mounting “barnacles” for racks, cargo cages, or bananas. This bike is truly ready for any adventure you have in mind, even if it’s out of this world!
