The mountains are calling and Super Deluxe Select+ is the answer. Loaded with podium-proven technology designed to elevate the hardest-hitting all-mountain bikes to new heights. From the all-new DebonAir+ air spring with tunable positive and negative air chambers to the optional Hydraulic Bottom Out to cushion the blow on heavy impact hits, the only tough decision is which trail to hit today. Features: DebonAir+ air spring maximizes fine-tuning potential, allowing you to tune both the negative and positive air volume to perfectly match your bike, desired ride feel, and the trail ahead.
