Frame

FLIP CHIP

Situated at the lower shock mount, the Flip Chip makes it quick and easy to adjust the geometry according to the terrain and riding style. The low position provides for a more aggressive headtube angle and a bigger BB drop, ideal for fast and rough tracks. In the high position, the headtube angle is 0.5 degrees steeper and the BB is higher. The higher BB gives more ground clearance and better performance on longer steep climbs.

FRAME PROTECTION

Made from super-tough and wear-resistant PA 66, the downtube protector is bolted on and can be easily replaced. It is designed to wrap around the bottom bracket and thus provide extra protection for the side walls of the downtube from impacts and scratches. Additionally, the rubber chainstay and seatstay guards help prevent unwanted noise from the drivetrain.

SEALED BEARINGS

Extra seals protect the high-quality, double-sealed full complement bearings to keep water and dirt out and help prolong the service life.

Chainsuck protection

The inconspicuous chainsuck plates protect the frame from damage caused by a dropped chain. This keeps sensitive areas out of harm's way and helps prolong the frame's durability.

Headtube

To optimize the weight to performance ratio, the contact surfaces for the integrated headset are pre-formed directly in the frame. Additionally, the ZeroStack design ensures a high level of durability thanks to the integrated bearing shells.

Internal Cable Routing

For optimal protection, all cables are routed almost completely through the frame. Uninterrupted internal tubes provide for easy cable replacement and also help prevent unwanted noise. Small ridges ensure the cable plugs sit tight in the frame to seal the cable ports and a cable clamp holds them securely in place as they exit the frame under the rocker link.

Virtual Four Link

Our award-winning V4L suspension technology provides sensitivity off the top, with good mid-stroke support and plenty of end-stroke progressivity. The nice pop helps get the bike airborne whenever wanted, while the end-stroke progressivity makes sure the rear shock doesn't bottom out even on monster jumps. The high amount of anti-squat keeps the rear suspension neutral and improves pedal efficiency.
