When the temperature drops and the snow clouds roll in to cover the landscape with a down comforter of fluffy powder, all we want to do is set aside the computer and break out a fat bike for burly fun in the snow. The 2016 Diamondback El Oso De Acero Complete Fat Bike lives for those snowbound days with the classic, clean lines of steel tubing and tank like tires that are ready to blast across the snowpack in search of winter adventure. The El Oso De Acero's frame is made from butted, heat treated steel, which is durable enough to weather winter abuse but nimble enough to take on challenging trails. Shimano's Alivio drivetrain provides a wide range of gear ratios to use as you navigate slick mud and deep snow, while Tektro Mira mechanical disc brakes promise consistent, reliable stopping power when you need it. Diamondback caps off the De Acero with extra wide rims and Chaoyang Cruiser tires. Measuring a beefy four inches in width, these knobby rubber platforms absorb bumps and float effortlessly across snow covered terrain in conditions that would be considered hazardous for road bikes or even most mountain bikes.
