26er 27.5 29er All Mountain Trail Enduro News Plus Sea Otter Classic

Both the Portal and the Hardline will come with FOX Float X2 shocks.

The Sea Otter Classic is a time for the cycling industry to show off it latest designs and Jamis Bikes can’t wait to show the world what it’s been working on the past two years.

At Sea Otter Classic in Monterey, CA Jamis Bikes will unveil their latest suspension design and bikes utilizing the technology. The new bikes were developed by Jamis’ in-house design team over the past two years utilizing the licensed 3VO suspension platform. 3VO was engineered and patented by industry veteran Chris Currie of Speedgoat Designs.

A more in-depth look at the Instant center progression of the 3VO design.

The 3VO or “Three Variable Optimized” suspension platform promises zero compromise suspension and pedaling performance in all riding conditions. Sal Crochiola, Jamis’ mountain bike product manager explains, “It only took one ride on Chris’s prototype to know this was something special and would be the future platform for Jamis suspension bikes. Incredible small bump sensitivity but also big hit plushness while maintaining super efficient pedaling was immediately noticeable.”

3VO Path

The Shock Rate for the Jamis Bikes Portal and Hardline from raising to falling.

Why the move to 3VO?
  • The unique instant center, center of curvature and axle path is said to eliminate unwanted motion when pedaling, regardless of position within travel or gear combination.
  • Lower, rearward moving instant center allows for high anti-squat with less chain growth to eliminate pedal kickback
  • Tuned multi-phase leverage ratio with initial rising rate for added pedaling stability
  • Consistent, balanced anti-squat and anti-dive cancels pedaling and braking forces

Is 3VO as responsive as previous designs?
  • Multi-phase leverage ratio combines both rising and falling rate for quicker impact response
  • Axle path and leverage ratio tuned to work together to keep the system active even when pedaling
  • Short distance from suspension instant center to rear axle for instant response
  • Virtual pivot location stays aligned with driveline, allowing suspension to remain active at every stage of travel
  • Initial rearward axle path allows the bike to be supple on small bumps and square edge hits

Jamis Bikes’ first offerings based around the 3VO platform will be the 130mm 29”/27.5+ Portal and the 160mm travel 27.5”/26+ Hardline.

    Interesting take on dual pivot design. New bikes don’t seem pushing the LLS geo much. But interested in hearing the ride reports.

    You have info on this? Do tell.

    I’d hate to admit I’d ever buy a bike based on how it looks but these certainly seem like a big step forward aesthetically. At least compared to Jamis’s DS options over the past few years.

    Holy cow! I had a Jamis with a single pivot and after 4 warranty rear triangles got rid of it. They couldn’t do a simple single pivot right and now they do this contraption? Good luck!

  • Bnystrom says:

    There appear to be at least 12 bearings in the linkage, plus the top and bottom shock pivots. This may be the “holy grail” of suspension design (who knows?), but how long will it last? I have nothing against Jamis, but like others above, I have one that had a rear triangle issue due to poorly aligned and installed bearings. This one has 50% more bearings, which really makes me wonder.
