CHRISTINI Long Travel Full Suspension Frame with Patented Integrated AWD system, Patented "Active Arc" Full Suspension frame design

A handlebar-mounted switch controls the AWD "shift on the fly" clutch. When the clutch is engaged, the rear spiral gear interlocks with the rear hub and power is transferred via internal shafts to the forward spiral gear set, which drives the CHRISTINI freehub.

Due to a slight gearing differential, the front wheel is not actively powered on smooth level ground. However, the moment the rear wheel slips, power is instantaneously transferred to the front wheel. Similarly, the moment that the front wheel decelerates, as in hitting a rock or starting to wash out in a corner, power and traction are transferred to the front wheel.

• Handelbar mounted AWD engagement switch.
• Spiral-Drive aluminum bevel and pinion gears.
• Aluminum interlocking clutch.
• Tubular aluminum drive shafts.
• Coated steel universal joints.
• Stainless sealed cartridge bearings.
• Total AWD system weight is 2.3 lbs.
