Technology

OCL+ Frame Joint
Robust folding technology
A heavy-duty update to our iconic OCL frame hinge, the OCL+ is built to exceed ISO 4210 and EN 15194 testing requirements. Leveraging the hinge design of the long-tail Tern Cargo Node, the OCL+ features a single-shaft design, advanced welding techniques, and robust gussets, so it stays stiff and strong during even the fastest commutes.

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.

Andros Stem
Adjust to fit
The Andros is our patented adjustable stem that lets you set your handlebars where you want—no tools, no fuss. In just seconds, you can set your riding position to long and low in a tough headwind, or upright and comfy for riding around town. You decide how you want to ride and the Andros makes your bike fit.

Magura® MT4 Hydraulic Disc Brakes
FREINS PUISSANTS
Hydraulic disc brakes give you excellent stopping power, working effortlessly even in rain, snow, or mud. All it takes is the gentle pull of just two fingers. With mineral oil-based brake fluid that is gentler on the environment than most hydraulic brake fluids, and Magura's Easy Bleed Technology, your Vektron is ready for a safer ride.
