The genesis of this model began in the early 1980s, thanks to some experimenting by Stelio Belletti. At the time, no frame maker had ever attempted to make a frame with a material so difficult to machine and weld as stainless steel. And in addition, this made it an extremely coveted and admired material. The difficulty of combining TIG welding with thin walled tubing had discouraged many manufacturers of the time. Stelio, once again, thanks to the INOX model, had shown the frame building world that his skills as a welder were unique, differentiating himself from the rest of the market thanks to a frame without conventional lugs.
Today this frame has evolved thanks to new materials and technologies, but it has maintained its classic style and charm that remains the same since it’s inaugural launch. Comfort and responsiveness are combined in a distinctive way, delivering a truly unique ride feel.
The fork, made using a Stelbel specific technique, is the first in the world to be made of Columbus XCr stainless steel. A feature that makes it precise when cornering while perfectly following the set trajectory. Comfort is always guaranteed from extremely effective vibration damping The cabling is internal and the frame can be built for mechanical, electronic or wireless groupsets.
The selection of tubing diameters is of the classic oversize type. The down tube is 31.6mm while the top and seat tube tube are 28.6mm. The head tube is 31.6mm which houses a fork with 1” quill, traditionally threaded but also available without thread for mounting a-head stems.
Dropouts, bottom bracket, brake bridge, head tube and fork are all embellished with engraved logos and details, just like a classic Stelbel frame.
The finish provides a rough brushed effect, leaving signs on the frame from the long hours of sanding and welding, in full Stelbel style. The raw metal is then covered with a transparent protective layer with a matt finish but alternative finishes are also available on request.
Each and every Stelbel frame is made to measure and designed with a custom geometry. After an order is confirmed and a deposit payment placed, the frame design will start based on the available information and documents (Measurements form, Bike-fit report, …). Customer will be interviewed to better understand riding style, wishes, goals and expectations for the new bike. A frame’s CAD drawing will be shared to be commented, analyzed, refined and eventually approved before manufacturing can start.
You can place an order directly with us via [email protected] or from one of our official retailer partners. An order is confirmed once a deposit payment is received via wire transfer or Paypal. Shortly after, a document providing an overview of the project details and a cad drawing of the frame will be shared for your approval. Pictures of the finished frame/bike will be shared with you prior to requesting the final balance payment. In case you’re considering coming to visit us in Bergamo to discuss the details of a project face to face, or to pick up your new frame/bike, you will be made very welcome by our team.
