As the first âplus� bike to hit the market, Krampus changed the way many people approach trail riding. Itâs shown people the light of how high volume, large diameter tyres can vastly improve the ride experience. Itâs also done a bang-up job dispelling the myth that big tyres make you slow.Krampus is kind of like the opposite of a mullet: long in the front and short in the rear. With a long top tube and compact chain stays, it takes trail-shredding abilities to the next level. A mullet may be business in the front, party in the back but Krampus makes partying its business.
