Mixed wheel sizes are the talk of the town! After a lot of testing and processing opinions, we have decided to implement a solution that we truly believe makes a lot of sense for many riders. A big, fast rolling 29” wheel in the front plows through rough terrain, and a smaller 27.5 wheel in the rear is tucked in and allows more suspension travel to be applied without fear of conflicts with the frame or body parts. On timed runs, this setup has proven to be the fastest, especially for smaller riders. Let's not forget that this is still a Define - which means it is built around a gorgeous alloy frame with custom hydroformed tubes, hidden external cable routing, big bearings and radical geometry!


Alloy frame with custom hydroformed tubes & double pass welds

Adjustable BB height

Progressive geometry with 44 mm fork rake

29” front / 27.5” rear wheel combination

170mm front / 160mm rear travel

Fox FACTORY suspension

SRAM X01 1x12 drivetrain

The beautiful carbon Define is now available in metal. It was a big challenge to translate the complex lines of this bike to another material, and we have sweated every detail of this high-end alloy frame to make it as light and as sexy as possible. Some of the unique features include an adjustable BB height and semi-integrated cable guides - a practical and elegant solution of the internal / external cable routing dilemma. Big sealed pivots keep it stable and guarantee long periods of smooth, service free function. There are a few things that we borrowed directly from the Snabb - and that is the kinematics of the 4-bar suspension that everyone loves (Pinkbike: "There is so little pedal-induced bobbing at play here that it sort of boggles the mind”).

Frame size recommendations:
S 160cm - 170cm
M 170cm - 182cm
L 180cm +


You can raise the BB height by 5mm from the stock settings by using the adjustable shock mount or you can completely transform the bike by changing the shock mount & shock (changes travel from 155 mm to 130 mm or vice versa).




The pivot that is most difficult to replace is hidden inside the frame and remains completely isolated from dirt and water inside the frame.


The cables appear to be threaded through the downtube and chainstay...



But actually, they are only hidden in a special channel in the construction. Easy to replace anytime, anywhere!
