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.

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!
