Cuadro Passoni Top Force Disc personalizado con kit de acabado

Passoni has been building titanium frames in their Vimercate atelier, just outside Milan, since 1989. Few builders have stayed as committed to the material across as long a span — and fewer still have turned it into something that looks like art while performing like a race machine. The Passoni Top Force Disc Custom Frameset with Finishing Kit is a made-to-measure titanium road disc frameset built to your geometry and finished to your specification. It carries the Top Force name — a lineage that traces directly to Passoni's early racing frames, the ones that accumulated Grand Tour stage wins in the early 1990s while riding under sponsors' decals. The people in the peloton knew what they were looking at. The casual observer did not.

At the heart of the Top Force Disc is a frame built from two grades of titanium, each used where it performs best. The main tubes — downtube, top tube, seat tube, chainstays, seatstays — use grade 9 titanium (3Al/2.5V), seamlessly drawn and shaped to Passoni's specification. The downtube is ovalised, the chainstays run an S-shaped taper oval, and the seat tube transitions through carbon-titanium construction, all designed to concentrate stiffness precisely where power transfer demands it. The headtube, bottom bracket shell, and disc dropouts step up to grade 5 titanium (6Al/4V) — a harder, stronger alloy — CNC machined at the atelier for dimensional precision and long-term durability at the frame's highest-load junctions. This is not a binary choice between "titanium feel" and "race stiffness." It is both, engineered at the alloy level.

The disc-specific architecture is one of the more refined details on the Top Force Disc. Passoni machined bespoke dropouts from grade 5 titanium with Ergal inserts sized for 12mm thru-axles, integrating disc brake support without adding visual bulk or compromising the frame's clean profile. The T47 bottom bracket and conical integrated headtube — 1-1/8" upper, 1-1/2" lower — accommodate modern component standards while keeping compatibility broad. The Columbus Futura carbon fork, custom specced for Passoni with a 100 x 12mm thru-axle, is tuned to match the frame's ride character: light at the front end, precise through corners, with enough compliance for the long days that titanium is built for.

Design Benefits

1. Two grades of titanium, working in concert. Grade 9 gives the frame tubes their natural compliance, vibration damping, and low weight — the qualities that define a well-built titanium road bike. Grade 5 at the headtube, BB shell, and dropouts provides the dimensional hardness and strength that disc braking forces and bottom bracket loads demand. Using both grades where each excels is what separates a hand-built custom frame from an off-the-shelf one.
2. Made-to-measure geometry. No stock sizing here. The Top Force Disc is built to each rider's exact morphology, starting from a fitting and ending with a frame specific to that rider's reach, stack, and riding position. At this level, the geometry should fit you the way the tubing fits the frame: precisely and without compromise.
3. Disc integration by design, not adaptation. Passoni's approach to disc brakes on the Top Force Disc starts with metallurgy and geometry, not retrofitting. The CNC-machined dropouts were conceived for this application from the outset. The thru-axle standard, Ergal inserts, and disc caliper mounts are integral to the frame. The result handles disc braking loads the way titanium should: cleanly, without flex, and without visual clutter.
4. The Finishing Kit. This is how Passoni turns a race-ready frameset into a cohesive object. Stems, handlebars, seatpost, and bottle cages can be color-matched and finished to the rider's specification. Graphics are applied by sandblasting or anodizing directly into the titanium — not decals, not paint. The finish becomes part of the material itself, which means it will still look exactly right in twenty years.

Final Take

The Passoni Top Force Disc is for riders who have decided that a standard production road bike, however accomplished, is not the answer. This is a custom titanium disc frameset made by hand in Italy, built to your measurements, finished to your specification, and backed by more than three decades of Passoni's single-minded focus on the material. At $10,250 with the finishing kit, it is genuinely expensive and genuinely one of a kind. Riders who commission one tend to keep them for the rest of their cycling lives.
