As the first "plus" bike on the market, the Surly Krampus has changed the way many people approach trail riding. It shows how large volume, large diameter tires can significantly improve the driving experience and dispels the myth that large tires make you slow.
With a long top tube and compact chainstays, it takes trail tackling ability to the next level. Equipped with a lot of attachment options for transport equipment, it is also well suited if you get the travel bug.

- Compatibility with most mountain bike standards makes it the perfect all-rounder (although rim brakes are not possible)
- Tire clearance for 29x3"
