When 27. 5 inch wheels hit the market like a ton of bricks, the folks at Ibis were able to respond relatively quickly, due to the ability to fit a 27. 5in tire inside the existing Mojo HD frame. This wasn't an ideal solution, though, so once it was clear that the new wheel size was here to stay, they went back to the CAD machines and created an all new Mojo designed specifically for 27. 5 inch rubber. The Mojo's always utilized the famed DW link for suspension. This design completely isolates pedaling and braking forces from the suspension kinematics and makes the Mojo feel like a perfectly adequate cross country machine, until the trail gets a little more vertical and the Mojo shows what it's really about rallying downhill. The Mojo's 67 degree head angle and 6 inches of travel is a little on the short and steep side compared to other bikes in this category, but the DW link's such a solid system that Ibis decided to back the head angle arms race off a bit to create a bike that was a little fasterhandling. They've matched the slightly steeper head angle with a slightly lower than average bottom bracket for better stability, and shorter than average chainstays to maintain the quickness that comes with most Ibis frames.
