Bike info

This is the biggest bike in the Define range, and is something of a crossover between Enduro and Downhill. It’s a BIG, capable bike. Mixing wheel sizes is the best solution for a bike like this! 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!



- Tough alloy frame with custom hydroformed tubes & double pass welds
- Progressive geometry with 44mm fork rake
- 29” front / 27.5” rear wheel combination
- 180mm front / 170mm rear travel
- ROCK SHOCK ZEB fork W/ 38mm stanchions
- X-fusion VECTOR coil shock
- X-Fusion Manic dropper post
- New SHIMANO deore 1x12 derailleur
- New SHIMANO DEORE 4-piston brakes
- Schwalbe Big Betty tires

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”).

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!
