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!
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.
Hybrid Cable Routing
The cables appear to be threaded through the downtube and chainstay, but are actually hidden in a special external channel within the frame structure — making them easy to replace anytime, anywhere.
