Product details

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.

The frame features Gnot Boost 145 mm dropouts, allowing it to accommodate rear wheels in 12 x 142 mm or Boost 12 x 148 mm. Special adapters are required for use with quick-release axles, which are not included.
