The first steel frame with oversized lugs can now tackle gravel roads

The Portofino G builds on the Portofino’s unique design concept, bringing the oversized lugs’ unparalleled combination of comfort and reactivity on rough terrain. Paired with purpose-built Columbus GB81 tubing, the proprietary lugs allow the frame to soak up bumps and vibrations while retaining a true road bike feel. With the Portofino G, you’ll be able to tackle more demanding road conditions with confidence, with instant acceleration when you climb or get out of the saddle. It’s a gravel bike that will take away the shoulder and back pain that often comes from riding poorly paved roads for long distances… But it won’t take away a road bike’s distinct sensation of speed and freedom.

Like the Portofino R, its road counterpart, the Portofino G features Officina Battaglin’s new seat lug. Designed to accommodate a 31.6-mm seat post, the lug’s seatpost locking system employs an expander bolt clamp that allows more clamping pressure with less torque. There are no bolts in sight, making for a cleaner and more aesthetically pleasing look.

The increased space of the T47 bottom bracket shell allows for a fully hidden cable routing setup even when the frame is assembled with a mechanical 1X groupset. This setup will make your custom Italian build look clean while letting you enjoy the benefits of the most advanced gravel bike technologies.
