Fatties fit fine on our trusty all-rounder steed, which means we're out to tackle the stuff that leaves skinnier tires flailing, and we're doing it all with our gal Edna. Surly's Edna Fat Bike Tire makes skidding on snow and getting stuck in sand traps a thing of the past. A unique tread pattern bites the loose stuff and features a tight center tread that doesn't drag on hardpack surfaces.
