Surly Krampus Custom Built Bikepacking Bike


Krampus is a dedicated 29+ trail bike that can go over, off of, or through just about anything in its path.

DISCLAIMER: This bike was custom built by us and the components have been specifically selected for this build. It is available in three sizes because we can replace the X-Large frame (on pictures) with a Medium or Large frame that's in stock in the store.

Breaking the Mold with a 29er Bike

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.

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.
