Surly says...... As the first “plus” bike to hit the market, Krampus changed the way many people approach trail riding. It’s shown people the light of how high volume, large diameter tires can vastly improve the ride experience. It’s also done a bang-up job dispelling the myth that big tires make you slow.

The Krampus frame is constructed using the same custom-designed, frame-specific, Surly CroMoly “’Natch” steel tubes found on many of our other trail bikes.The main triangle’s tubes are internally butted with some tubes externally tapered, flared like a trumpet and ovalized to add stiffness and strength without adding weight. When you add in the 3” tires, it makes for a resilient and lively ride that’s durable and fun as hell.

Krampus is kind of like the opposite of a mullet: long in the front and short in the rear. With a long toptube and compact chainstays, 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. As Thor puts it: “Lean back, hang on, and ride that wild horse.”
