This is the biggest bike in the Define range. It’s basically a downhill bike that can be ridden uphill. Mixing wheel sizes is the best solution for a bike like this and 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 contacting the frame or body parts. 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!

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

OVERSIZED BEARINGS, SEALED MAIN PIVOT

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

HYBRID CABLE ROUTING 

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!
