Carbon C Frame
–
Juliana's C Carbon frames use the same proprietary processes of the highest spec CC Carbon frames to meet the same legendary strength and stiffness standards. But the use of a different grade of carbon material results in a minimal weight gain.
Travel
–
160mm Front / 150mm Rear
Wheel Size
–
27.5"
Lower-Link Mounted VPP® Suspension
–
VPP is based on the patented principle of having two short links rotating in opposite directions. This system provides huge design flexibility, allowing Juliana to manipulate shock rates to the intended purpose and character of each model; from short travel endurance bikes to World Championship winning DH machines. This redesign mounts the shock lower on the bike, making for an even better ride quality.
Proportional Chainstay Lengths
–
With rear ends that match the size range, this bike's geo and ride quality is the same for all riders.
