FRAME MATERIALS

Lightweight and strong High Modulus carbon fiber or triple-butted 6061 series aluminum tubing, featuring custom over-sized & tapered tubing for increased frame stiffness and durability.

ENDURO® BEARINGS

USA made Enduro® Max sealed bearings sustain 40% more load capacity than standard radial bearings & provide more lateral support for the multiple forces associated with mountain bike pivots. MAX bearings use CRC Marine Grease that will not wash out or breakdown under extreme circumstances.

10MM SHOCK HARDWARE

Our 10mm shock hardware is NOT the standard from our rear shock suppliers. We have to pay more for it and our production lead times are usually increased because we specify it. But the increase in lateral and torsional stiffness for our frames and the rear shock durability and performance is worth every extra dollar.

ONE AND ONLY

The 1x drivetrain philosophy is to make it simpler, lighter and more durable. Specific  chainring tooth profiles, clutch-type rear derailleurs and wide range cassettes are developed for an incredibly wide gear range and maximum control without the need to chain tensioning devices or guides.

Jamis Bullseye

TAPERED HEADTUBE

Riding fast with control requires steering precision, which starts with the front of the bike. Stiffening this area results in less wheel deflection, more wheel control. A full 1.5” head tube and steerer would achieve this, but would add unnecessary weight and bulk, and limit stem choices. But a tapered 1 1 /8” to 1 1 /2” head tube serves up a significant increase in rough terrain tracking and stability without much of a weight penalty compared to standard 1 1 /8” systems.

WHY THRU-AXLES?

Securing the rear wheel to the frame by threading a 12mm axle into the rear drop-outs is not only safer, it’s stiffer.  The rear wheel tracks directly in line with the frame, for more precise handling, so you can go faster with more confidence. The increase in stiffness of a 15mm fork axle improves steering & handling significantly. It also puts less stress on the fork’s internals, improving fork durability and performance. The hub drop outs provide a self centering feature for the wheel for fast, easy installation.

SHORT CHAINSTAYS

The rear wheel tucks in with short chainstays. With a 12×148 rear hub, you’ve got a stiff and responsive rear end.

BALANCED GEOMETRY

Portal and Hardline both feature Balanced Geometry. The combination of these individual attributes produces a system which optimizes responsiveness and dynamic performance regardless of trail condition or type.

"The construction is absolutely top notch..."

Jamis is all in with their 3VO project - to the degree that they chose a small, high-end manufacturer that caters to a hand-picked group of the world's most prestigious brands.

"More than meets the eye"

The Portal stays planted, rips, has the incredibly efficient 3VO suspension design and is overall a bike we would love to stay on...Simply put, this bike is up there with the best all-around trail bikes on the market today.

"Believe [most of] the hype."

The Portal pedals very well, with no lockout required. Ever. And as claimed, it was never overly concerned with how much sag I was running. There was no annoying pedal feedback and no noticeable brake jack...

"A unique approach to efficiency..."

The bike felt smooth and swoopy through blown-out berms and chunky rock gardens. On the climb up, I was really impressed with the climbing stiffness of the suspension—it felt super efficient...

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.
