Jamis Portal A2 - 2019

Details
Jamis hit the sweet spot with the Portal. With 130mm of front and rear travel, it offers enough suspension to take on any trail you have the guts to try, but is still svelte and nimble enough to pedal anywhere on the map. The 3VO suspension designed by Chris Currie of Speedgoat nails the bullseye of suspension kinematics: active and stable under pedaling and hard braking but sensitive to small bumps and ready for big, square-edged hits. RockShox deftly controls that rear travel, as well as handling suspension duties up front with a Deluxe R shock and Revelation RC fork, respectively. Portal A2 rolls fast and confidently on 29-inch Vittoria tires and comes with Shimano’s SLX 1x11 drivetrain, so you’ll have a broad range of gears at your fingertips, perfect for aiming at a mountain and pressing “Play.” Bringing the Portal safely back to low orbit takes nothing but a gentle squeeze of the Shimano MT500 hydraulic brake levers, delivering the power and confidence to master the trail. And, a KS dropper post ensures your body is in the right position for the task at hand, whether you’re grinding up the thirty-third switchback in a row or shredding down a buffed park jump line.
