Krampus Frameset - Andy's Apple RedPlus bike frame with Gnot-Boost rear spacing

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.

If you’re looking to ride through/over/off of obstacles, may the Krampus be your mighty steed. As Thor puts it: “Lean back, hang on, and ride that wild horse.”
