What makes Beargrease C Eagle 70 one of the most versatile fat-tire bikes? It starts with a carbon fiber frame that’s lightweight and stiff for less wasted energy. Balanced trail-bike geometry, 27.5 x 4.5" tires, and a dropper post ensure control, stability and traction over soft, steep, terrain and trail obstacles. Plentiful cargo mounts give you space to stow extra layers, your sleep kit, much-needed calories, and more. SRAM’s Eagle 70 drivetrain gives you the gear range to crawl over deep snow or find flow on groomed trails, plus the durability you want in a drivetrain that will take you from here to anywhere. Add it all up and it’s clear that Beargrease is a fat-tire bike capable of winter ultras, groomed trail riding, and whatever else you have your imagination set on.
