Moonlander runs 4.8˝ tires on 100mm rims. Such a large footprint allows you to ride them at very low pressure, which (as with a snowshoe) enables unparalleled traction and float over all kinds of terrain…wet stuff, roots, rocks, pebbles, gravel, sand, and many types of snow. Moonlander, like its name implies, is meant to go beyond where normal bikes, even normal fat bikes, can go. It is designed from the ground up to ride where there are no roads, no trails and no people.
Like all of our framesets, Moonlander is made of 4130 CroMoly steel, with tubing designed specifically for this frame. The frame’s geometry is not unlike a standard mountain bike, with a bottom bracket height that supplies plenty of clearance for bushwhacking and monster-trucking while remaining low enough for a stable ride. The toptube maximizes standover height while keeping the headtube fairly high so you can set up your rig with a comfortable, all-day-grind riding position.
The frame features 135mm-spaced horizontal ‘dropouts’ with a derailleur hanger, meaning you can set it up as a singlespeed, with an internal gear hub, or standard derailleur drivetrain. The rear end is offset 28mm to allow the drivetrain and wide tires to play nicely together. Moonlanders come with a 135mm O.L.D. non-offset fork, but if you like being able to swap front and rear wheels you could get one matching the rear offset. The fork sports a 51mm I.S. disc caliper mount designed for a rear brake, and mid-blade thru-eyelets and lower rack barrels for mounting a fender and rack (you’ll probably need to alter something to fit, but the option is there should you choose to).
