Jamis - Portal C2 Winter Dusk
1. INSTANT CENTER
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.
2. AXLE PATH
A rear wheel that stays planted while charging through rough terrain is crucial to providing an intimate connection with the trail. 3VO's initial rearward axle path allows the bike to be supple on small bumps and square edge hits while its tightly tuned relationship with the system's leverage ratio keeps the suspension highly reactive even while pedaling.
3. LEVERAGE RATIO
Imagine having two bikes in one, that's essentially what we've got with 3VO. The tuned multi-phase leverage ratio with initial rising rate provides an unparalleled pedaling platform while remaining keenly adept at sustaining repeated bumps without holdup.
Up to just beyond the sag point, the system employs a slight rising rate. Some designs claim an initial falling rate with high initial leverage improves sensitivity and responsiveness, but these claims seem more driven by a need to market a deficiency than by any genuine benefit. Why? Because up until the sag point of the bike, sensitivity and responsiveness are primarily felt when the suspension is able to extend, not compress.
