2019 Tern Verge D9 Folding Bike
The Verge D9 is a trailblazer. Born out of our 451 Verge design philosophy, it has bigger race wheels, T-Tuned™ geometry, and a wide 1x drivetrain. It’s about as much value as we could condense into one bike, and it’s ready for any upgrades you can throw at it.
OCL™ FRAME JOINT ADVANCED FOLDING TECHNOLOGY
The key to any folding bicycle is the frame, and specifically, the folding joint at the heart of the frame. Done well, it locks the two halves of the frame together without any hint of movement or sound. It should be easy to operate and work flawlessly year after year. The OCL Joint does all of these things and is a new reference in folding frame technology.
N-FOLD™ TECHNOLOGY THE FASTER FOLD
With N-Fold Technology, Tern bikes fold small and fast—in three easy steps. It’s simple enough for anybody to master. And with the handlepost folded to the outside of the package, Tern bikes can also roll when folded for easy transport.
DOUBLETRUSS™ TECHNOLOGY STIFFER BY DESIGN
The rear half of Tern frames use a patented 3D structure we call DoubleTruss to build in extra stiffness. It helps resist torsional forces so our bikes flex less. That means increased stiffness and much better power transfer from the pedals to the rear wheel. The proof’s in the ride.
T-TUNED™ GEOMETRY FULL-SIZED RIDE, COMPACT FOLD
At Tern, we endeavor to build fast-folding bikes that ride like full-sized bikes. Our T-Tuned geometry is the culmination of our commitment. We’ve tweaked the wheelbase, rake, and seat-tube angle of our design to deliver the most confident and stable ride of any bike in our lineup. Ride one and try it. Take your hands off the handlebars if you’re feeling bold.
PHYSIS™ 3D HANDLEPOST THE NEW BENCHMARK
Five patented technologies and unique manufacturing technology add up to the strongest, stiffest folding handlepost available. The Physis uses a special manufacturing process called 3D forging, which forms the post from a single piece of aluminum, eliminating all welds.
SYNTACE VRO STEM FIND YOUR FIT
Your bike should adapt to fit you―not the other way around. This adjustable stem allows you to position your handlebars further, for a more stretched and aggressive riding position, or up higher for increased comfort.
SHIMANO SHADOW DERAILLEUR STREAMLINED SHIFTING
Originally developed for mountain bikes—for extra durability and to avoid catching on trail debris—the Shadow derailleur is streamlined and incredibly resilient, which comes in handy when you need to transport your folded bike. Whether your bike is bagged on the subway or riding in the trunk of your car, everything is neatly tucked away.
1X (“ONE-BY”) DRIVETRAIN SIMPLIFIED VERSATILITY
There’s a revolution in drivetrains across the industry. Thanks to the recent introduction of hyper-wide cassettes from SRAM and Shimano, it’s possible to achieve massive gear ranges with only one chainring up front. That makes 1x an ideal configuration for folding bikes, because it reduces maintenance, weight, and complexity. Enjoy all the range of a 20-speed drivetrain, with none of the complications.
