10. Surly Krampus MTB frame kit, 29+, S, first loser silver
As the first plus bike to hit the market, the Krampus has changed the way many people approach trail riding. It has shown that large-volume tires with a big diameter can significantly enhance the riding experience. Additionally, it has dispelled the myth that big tires slow you down. The Krampus is somewhat the opposite of a mullet: long in the front and short in the back. With its long top tube and compact chainstays, it elevates trail shredding capabilities to the next level. While a mullet might be business in the front and party in the back, the Krampus makes party its business.
