The Portofino G

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


The Portofino G

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.

We build each custom frame with one goal: to create a dream bike that fits your specific preferences while offering you an unforgettable, personalized experience.

Discussing the endless possibilities of a custom build requires a lot of time and dedication. We use phone calls, email updates, photos of the building process: but such a personal approach wouldn’t be possible if we focused our efforts on producing a huge number of pieces.

That’s why we’ve decided to cap the annual production of the Portofino G at only 70 custom frames (or complete bikes).

Each frame comes with a numbered plate brazed to the top tube that authenticates its uniqueness and will make it an exclusive item to treasure forever.

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.

No matter how dirty the terrain you ride may be: a custom bike designed and built for you should always look good and make you proud of it. And while matte paint has proven to be a safe choice for most gravel bikes, the best option to stand out from the pack even on gravel is our signature cromovelato. The model-specific paint scheme features polished chrome that fades to a cromovelato color through a chrome filigree. A look that is likely to turn heads, and a look that you’ll be able to personalize thanks to our premium cromovelato tints selection.
