Krampus 29+ Frameset – Sage

Breaking the Mould 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 tyres 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.
