Product Description

Many of you are probably familiar with the Moonlander. This was our first bike to run 4.8˝ tires on 100mm rims. Such a large footprint allows you to ride them at very low pressure, which bestows a rider with lots of traction and float over all kinds of terrain. 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 cro-moly steel, with tubing designed specifically for this frame. The frame features 135mm-spaced horizontal ‘dropouts’ with a derailleur hanger; a setup that still has it’s merits in versatility and availability of parts. The rear end is offset 28mm to allow the drivetrain and wide tires to play nicely together. 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. 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 front 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).

Years ago, our Art Director got himself this paint combo on his Moonlander and everyone thought it looked so cool, we decided to produce it and put some damn nice parts on it. It’s spec’d with a 1×11 SRAM X1 drivetrain which gives you a nice wide gear range that’s versatile enough to truly go anywhere, through anything, like a Moonlander should, and on the Surly O.D. crank you’ll find a Surly stainless steel X-Sync chainring to further the performance and durability of this drivetrain. If the speed at which you are traveling begins to frighten you or you are approaching a stop sign, you’ve got a nice set of hydraulic SRAM Guide brakes to slow you down.
