Jamis Portal C1
Details
Portal - noun: DOOR, ENTRANCE; especially a grand or imposing one.
Pass boldly through to the other side and impose on the most fun you've had on two wheels with the Jamis Portal C1. Its high-modulus carbon fiber frame swings your rear wheel through 130mm of micro-tracking 3VO suspension, renowned for its trail-contouring ability that goes hand-in-hand with big-hit burliness. A 140mm Fox 36 Float fork easily handles the rough stuff up front, ensuring your trail-spec'd Stan's NoTubes Arch carbon wheels track right where you want them, ready and willing to dig deep, wrapped in Vittoria's Martello tubeless tires.
The entire trail opens to you when you've got the proven combo of a huge-range SRAM XX1 Eagle 12-speed drivetrain and TRP G-Spec Trail SL brakes to ensure you have the leverage when you need it, the speed when you want it, and the power to reign it all in when the speed gets critical. And, the Portal will feel as familiar as walking out your front door thanks to a rider-tuned Race Face cockpit, and an instantly dialable stance, courtesy of your Fox Transfer dropper.
A dropper seatpost allows you to quickly lower and raise your seat to give you an ideal riding position. Dropping your seat creates a lower center of gravity for better control and maneuverability on steep descents, while raising it puts you at normal riding height for efficient pedaling.
Construction can include either hydraulic- or cable-actuated systems and the post’s travel can either be infinitely adjustable or stopped at set intervals, depending on the model.
Dropper seatposts come in standard lengths and diameters and vary by the amount of travel.
