Named after a giant wolf in Norse mythology, the new Otso Fenrir lives up to its name as a beast among bikes.  Designed to clear 29 x 2.6 inch tires (even 3 in the front) or 27.5 x 2.8 tires, this bike has no shortage of clearance for fat meats.  The frame is stainless steel with corrosion properties, making it an ideal bike to get dirty in the mud.  Find out what I think about it in the full review.
