The Surly Krampus was the first “plus” bike to hit the market, revolutionizing how riders approach trail riding. Its high-volume, large-diameter tires dramatically improve traction, control, and ride comfort — all without compromising speed. Designed for aggressive singletrack, technical descents, and extended trail adventures, the Krampus dispels the myth that bigger tires slow you down.

This trail-ready rig combines a 100% Surly Chromoly steel frame with a modern RockShox 35 Gold RL aluminum fork, 120mm of suspension travel, and full compatibility with contemporary MTB standards. Dropper post support, 44mm headtube, Gnot-Boost rear spacing, and thru-axles make it easy to fit current components, while clearance for 29" × 2.6" tires ensures optimal traction and stability.

Whether you’re building a parts-bin dream bike or tackling rugged trails out of the gate, the Krampus delivers confidence, durability, and speed on big tires — your ticket to mastering the most demanding terrain.
