The construction of the Inossidabile frame requires incredible skill.
The result is a bike with a strong soul as the material it's forged from
"We wanted to make a bike that would make the hearts of heroic cycling enthusiasts beat faster, whose material is famous for its strength and durability.
This is the origin of Inossidabile, an ideal combination of historic cycling and contemporary technologies"
An unassailable stainless racer. The Inossidabile is created for those seeking the most
modern and aggressive of steel bicycles.
Crafted from Columbus’ unmatched XCr stainless tubing, the extreme hardness of this
material requires the highest degree of skill to work with. Pushing our artisan frame builders
to the limits of their abilities, once formed into a frame, it’s a material that imparts a ride
quality formerly unimaginable. Stanch yet forgiving, robust yet incredibly lightweight, even in
its raw form, it’s also both beautiful and impervious to the elements.
Rigid when pushed and responsive to every steering input, the Inossidabile uses a subtly
sloping geometry that prioritises speed and agility.
Based around a frame composed of broad diameter tubes, the wide junctions between these
ensure the bicycle flexes only where this trait is desirable. Each of the frame’s gleaming
stainless tubes is also heavily worked to produce perfectly tailored characteristics, resulting
in a sublimely composed ride.
Made possible by Passoni’s collaboration with Milan-based tubing makers Columbus, these
efforts are visible in the profile of the Inossidabile’s unique drop-shaped downtube and bi-
oval seat and top tubes.
Machine-perforated and cold drawn countless times before being welded together, this
allows the Inossidabile’s tubing to achieve the exact taper and profile required. Also unique
in the way its grain structure remains unaltered by the heat of fabrication, this ensures the
material’s incredible characteristics are carried across the entirety of the frame.
Timeless despite its oversize tubes, the Inossidabile benefits from many reliable standards.
Towards the front of the bike, its 1 ⅛” headtube is created from a seamlessly drawn tube into
which a pair of semi-integrated bearing cups are then welded. Housing the bike’s custom
Columbus Futura SL fork, this provides either a 45 or 50mm rake. Elsewhere a threaded
bottom bracket shell and easy to adjust external cable routing provide both convenience and
Ensuring the look of the bicycle remains as contemporary as its mechanical performance,
the finish of the frame itself is also near impervious to damage. The result of around 30
hours of hand polishing, its mirror finish requires no further treatment. Showing off the
unparalleled technology and craft that goes into creating the Inossidabile, subtle sandblasted
graphics are the perfect foil to its blemishless exterior.
L'Inossidabile è stata creata per chi cerca la più moderna e aggressiva delle biciclette in acciaio. Realizzata con gli impareggiabili tubi in acciaio inossidabile XCr di Columbus, l'estrema durezza di questo materiale richiede il massimo grado di abilità nella lavorazione. Una volta trasformato in un telaio, il materiale è in grado di offrire una qualità di guida inimmaginabile. Robusto ma indulgente, robusto ma incredibilmente leggero, anche nella sua forma grezza è bello e resistente agli agenti atmosferici.
We believe in the beauty of simplicity. By constantly analysing, evolving and refining we aim craft exceptional bikes and deliver an unprecedented level of service. Over the decades we have applied this methodology to our Made-to-Measure process.
