A Frame from Another Time
The INOX was born from experimentation. In the early 1980s, working with stainless steel for bicycle frames was almost unthinkable. The material was difficult to shape, even more difficult to weld and unforgiving of mistakes.
Stelio Belletti chose to pursue this path regardless. The result was a lugless frame, entirely TIG welded and built from thin-walled stainless steel tubing at a time when very few possessed the skill or confidence to attempt it. INOX quickly became an object of admiration, both for its technical audacity and its unmistakable presence.
Today, this project exists not as a nostalgic exercise, but as a conscious choice. INOX stands as a reminder that certain ideas do not lose value over time.
Stainless Steel and Experimentation
INOX is built using Columbus XCr stainless steel, a noble and technically demanding material. Its resistance to corrosion, combined with its mechanical properties, allows for a frame that remains reactive, precise and durable over time.
XCr offers a rare balance of stiffness and elasticity, delivering a ride that feels alive when pushed, yet composed and fluid across long distances.
TIG Welding and the Absence of Lugs
True to its origins, and consistent with Stelbel frames from every era, INOX is built without lugs. Every tube junction is TIG welded, following the same principles that defined the original frames.
Working with stainless steel and thin-walled tubing requires absolute control of heat and execution. Each weld is shaped and refined by hand, not to impress, but to achieve continuity, balance and structural integrity.
This approach reflects Stelbel’s identity today just as it did over forty years ago.
The Stainless Steel Fork
One of the defining elements of the INOX is its fork. Entirely built in-house by Stelbel, it is constructed from Columbus XCr stainless steel and follows the same design philosophy as the frame.
There are no pre-assembled or outsourced components. The fork is shaped, welded and finished internally, respecting historical proportions while delivering exceptional precision.
On the road, it provides a sense of total control, especially when pushed hard through corners, transmitting confidence and accuracy in a way few modern solutions can replicate.
Ride Feel and Timeless Comfort
INOX delivers a ride quality that feels both distinctive and familiar. Classic oversized tube diameters, combined with stainless steel, create a frame that reacts promptly under acceleration while maintaining a smooth and composed feel.
Comfort and responsiveness coexist naturally, offering sensations that reward experienced riders and invite long hours in the saddle. It is a bicycle that communicates clearly, encouraging an engaged and confident riding style.
Finish and Details
The finish of the INOX reflects the honesty of its construction. Surfaces are carefully brushed, leaving visible the traces of a long and meticulous process of weld refinement and hand finishing.
The frame is protected by a transparent matte clear coat, enhancing durability while preserving the raw appearance of the stainless steel.
On request, customers may choose special finishes or more elaborate designs, as seen on the INOX presented on this page, enriched with one of our signature colours, the so-called Campari Red.
Details such as dropouts, bottom bracket shell, rear bridge, head tube and fork crown are embellished with engraved logos, echoing classic Stelbel frames and reinforcing a sense of continuity.
A Living Statement of Heritage
INOX exists because Stelbel has a heritage worth preserving. It is a living testimony to Stelio Belletti’s vision, his technical skill and his willingness to challenge conventions.
Chosen by true enthusiasts, nostalgics and riders drawn to its unique character, INOX remains a frame meant to be ridden, not simply admired. A bicycle that proves that timeless ideas, when executed with care and conviction, never fade.
