Ti Omega’Beast Frame

As Fat as it Gets!

When the O’Beast isn’t enough, you must call upon the Omega’Beast! Our fattest fatbike yet (and the first production fatbike with more than 5″ of tire clearance), the Omega’Beast can cross snowfields, climb stairs, and descend rock gardens with ease thanks to clearance for tires OVER 5″ wide! There was no avoiding the 197mm rear spacing  on this one…maximum tire clearance is needed! The Omega’Beast comes in a brushed (polished) finish with a bead blasted logo only and has rack mounts. The frame has clearance for all tire/rim combinations: 29×3, 27.5×4, 26×5+.

Is there a little detail you don’t like? Want to tweak the geometry a bit? Have a cool idea for a frame? As with all our titanium frames, customization is no problem. For an extra $300 we can edit this frame to your liking, or start completely from scratch. Contact us any time and let us know what you’re looking for. We can help you design a frame and give you an accurate timeline for how long it will take to build.
