Jamis | Portal C4 Full Suspension Bike

With the 3VO system’s unique virtual pivot characteristics, we’re able to combine the efficiency of a hardtail with the proper support of precisely-controlled active suspension. This is how every full-suspension bike should ride. 

KEY ADVANTAGES OF THE 3VO INSTANT CENTER

COMPLETE EFFICIENCY
The most efficient propulsion, with no loss of pedal energy due to suspension movement, regardless of gear combination, wheel travel, terrain, and rider power output.

INSTANT REACTION
With all drive forces being directed into and through the center of curvature or “virtual pivot” at all points in the travel, the design remains extremely active and supple to absorb even small impacts.

NOT DEPENDENT ON GEAR COMBINATION, SAG, OR REAR SHOCK TUNE
The unique pivot location created by the patented 3VO design performs regardless of what gear you’re in, how much sag you prefer, or the specific damping of your rear shock. While we always recommend well made shocks, no special damping or tune is required, and coil springs are welcome.

BRAKE FORCES ISOLATED
System remains highly active and responsive during even the most aggressive braking, and high anti-rise counteracts forward weight shift to maintain stability.
