The frame. To understand this frame, one must first comprehend and appreciate the single pivot. Not just any single pivot. The high positioned, “swing-link” stiffened, linkage driven, low leverage ratio givin’, FOES single pivot. This suspension design is simple, dependable, quiet, and plush. The forward raised pivot position reduces pedal feedback while the big-ass bearings allow the stout swingarm to devour hits, all while remaining pre-loadable at the lip (i.e. smooth through rocks but jumps well too) and riding low in the travel through tight g’d-out turns. Laterally, it’s stiffer than most hardtails all the way throughout its dependable, predictable, durable, creakless travel…ride after ride after ride.
Good? Good. Now that you understand the Foes pivot design, we move on to the Mutz specifics. The travel is adjustable, 5″ or 5.5″. Why? Because, based on the target chainstay length, it’s where the best possible ride met the most travel met the room-for-the-wheel limit. It also allows for longer travel forks, which are sure to come (Fat-Pike? SRAM? If you’re reading?).
Front derailleur. Yes. 2x fits fine, with no chain/tire contact in lowest gears (even with the ‘Dozer). High direct mount, 2×10 cage. Foes will supply the spacer and bolt.

- Wheelbase – 46.25″
- BB Height – 13.25″
- Standover – 31.75″
The ride. Of course the thing rips at speed. It also pedals about 10 times better than the big-wheeled looks would have you to believe.
On the trail, the Foes hooks-up, tracks, and drives through turns like a snowboard through fresh powder. As for bumps, rocks, roots, and whatnot, it feels like nothing we’ve ever ridden.
With conventional MTB’s, the bumps and hits are felt in the wheels just before the suspension activates/compresses. No matter how soft the suspension, this is just a truth of “normal” suspension bikes. Add fat tires run at about 10psi to this equation, and that initial hit is absorbed completely. What you get is a feeling of floating over those bumps (rock gardens, root patches, etc.) with maintained stability like no other. This is where we see the suspended fatbike, as a category, becoming many riders’ year-round, daily trail bike. We know it will be for us!
