Factory Description
Specialized Fatboy SE mixes fat bike fun with legendary Specialized performance. This value-packed behemoth delivers with a lightweight aluminum frame paired with an aluminum fork. All that rolls on 4.8-inch Ground Control tires that devour everything in your path. The super-wide aluminum rims give you stability and durability to roll through the rocky, root-filled trails like butter. It all gets going with SRAM’s slick-shifting 2×10 X5 drivetrain while dependable Tektro Aires mechanical brakes rein it in. Finished out with an excellent Body Geometry saddle and grips, the Fatboy SE opens up a whole new world of rideable terrain.
