During the early 90’s De Rosa embarked on what has become a multi-generational voyage with Titanium in order to perfect the frame known as Treduecinque by dedicating a significant portion of the research, development and manufacturing capacity facilities at the De Rosa office to this unique project. Treduecinque has developed a cult following despite the changes required by its evolution. The dedication, patience and time required to work with this incredibly strong material also helps us instill the joy and beauty of the ride into every frame we create! Strictly and only tailor made.

Treduecinque is a work of art made directly by the artisan frame builders in Cusano Milanino; pride describes both their craftsmanship and your ownership. The frame geometry at the heart of each Treduecinque bike can be made to measure and parts specified to fulfil your unique requirements, get in touch with us to find out more.
