Felt DD 10 proves that it is absolutely fine to get fat in the winter! The burly aluminum frame encloses a pair of massive, terrain-trampling 4-inch wide Schwalbe Jumbo Jim tires that float over, across, and through mud, sand, and snow. Of course its 100mm RockShox Bluto fork and nimble geometry makes it fun on perfectly dry singletrack too! Gotta climb some hills on the way? Shimano's XT 1x11 gearing and Race Face cranks propel you to the top and keep on shifting through the muck while a pair of Shimano Deore disc brakes scrub speed on the way back down. And even though the wheels and tires are fat, Felt's carbon seatpost and handlebar are light as can be.
