Bike info

Fun, fun fun! These three words sum up this new addition to the Define range. The new bike boasts the beautiful lines of the high-end carbon Define and comes fitted with coil shocks for great small bump sensitivity. We designed the geometry to give the bike a perfectly balanced feel and put it on 27.5” wheels, making it the most playful big bike in our range. The Define 160 has semi integrated cable routing (elegant but easy to access), and adjustable BB height. The H3C is X-Fusion’s new lightweight coil shock that has a three position platform, rebound and low speed compression adjustment. Note: our suggestion is to go for a smaller size if slopeduro is your thing, or if you want to spend most of your time jibbing and tricking.


- Tough alloy frame with custom hydroformed tubes & double pass welds
- Progressive geometry with 37mm fork rake
- 27.5” WHEELS
- 160mm front / 160mm rear travel
- ROCK SHOX front suspension (35 GOLD RL)
- X-Fusion Rear suspension ( hc3)
- X-Fusion Manic dropper post
- New SHIMANO deore 1x12 derailleur
- New SHIMANO DEORE 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”).

Specifications subject to change without notice. Actual colours and design may vary slightly from the images on the website.


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!
