Carbon CC Frame

CC denotes Juliana's highest grade carbon fiber frames. Use of the very best materials in the composite results in the lightest, best handling bikes.

Travel
–
130mm Front / 120mm Rear

Wheel Size

29"

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.

The Glovebox™

Seal whatever you want to carry on your ride inside your downtube. Secure and easy to access, the Glovebox™ has a Tool Wallet and Tube Purse inside, to help organize your stuff too. Simply cavernous!

Proportional Chainstay Lengths

With rear ends that match the size range, this bike's geo and ride quality is the same for all riders.

  Used For

  Trail

  Trail bikes are the quintessential “mountain bikes.” If you’re heading into the woods expecting to do it all on two wheels – climbing, technical sections, AND fun descents – you’re looking for a trail bike.
