Bombing technical descents, hitting the jump lines, or racing in an enduro series, the HD6 is one of our top choices when we need an aggressive enduro bike that can do just about anything. Coming a long way from its older sibling, the HD5, the HD6 received many improvements, including 15mm of added rear suspension travel and 10mm more fork travel to make it more capable. In addition, the HD6 takes things up a notch and brings us a mixed-wheel setup for the best of both worlds, with a fast-rolling, 29-inch wheel up front and an agile 27. 5-inch wheel in the rear. 165mm of DW-Link suspension allows the HD6 to eat up technical trails with ease, climb like a trail bike, and have a plush yet supportive ride.

Short and agile chainstays across all sizes ensure an agile bike that allows us to move the back end around corners easier and aids in getting the wheels off the ground. A new link design gives the HD6 a progressive leverage ratio and a coil-compatible shock, while the lower link has been rotated 90 degrees, allowing us to access it without having to remove our cranks. Integrated chainstay and downtube protectors keep our frame looking new, and a shuttle guard allows us to throw our bike into the back of our truck bed so we can drive to the trailhead worry-free.

To start, Ibis's carbon frame is made with premium carbon fiber for a strong and lightweight frame weighing just 5. 5 pounds. Shimano's XT 12-spe...
