4-way Mino Link
Easily adjust the suspension and geometry four different ways for where and how you ride. With the flip of a chip, you can ride with more or less progressive suspension, and tweak your geometry for a slacker head tube and lower BB or steeper head tube and higher BB.
New internal storage with new BITS bags
New internal frame storage bags make it easy to ditch the pack and still carry your ride essentials.
BITS: Your trailside savior
Cleverly integrated into the steerer tube, the included BITS multi-tool has everything you need for trailside adjustments and repairs.
Active Braking Pivot
Active Braking Pivot allows our engineers to tune how the suspension reacts to acceleration and braking forces independently. That means you get more confident control when you need it most.
