A Tribute to Antenore Belletti
The Antenore is a tribute to the man whose technical curiosity and workshop mastery shaped the roots of our brand. It reflects a way of building that values proportion, balance and craftsmanship.
Its geometry is racing-oriented, but the riding experience is unique, elevated by the properties of stainless steel. The Antenore feels composed and predictable, offering immediate control, stability at speed and a reassuring behaviour on climbs, accelerations and technical descents.
The Nature of XCr Stainless Steel
XCr is one of the most advanced stainless steel alloys developed for framebuilding. Produced by Columbus, our long-standing partner and a reference point for high-end tubing, XCr offers exceptional mechanical properties and a high level of resistance to corrosion.
Its martensitic structure makes it demanding to work with, particularly when TIG welded. Only a few builders choose to engage with this material, as it requires precision, experience and an approach that leaves little room for error. When shaped with care, XCr yields a frame that is light, reactive and intuitive, capable of filtering vibrations while maintaining a precise feedback.
Its durability is part of its appeal. An XCr frame is designed to accompany many years of riding and to be appreciated beyond a single generation.
A Fork Designed for Balance
The A4 generation introduces our proprietary Evoluzione carbon fork, developed to complement the frame in both function and form. It offers precise steering, accommodates fully hidden cable routing and preserves the visual harmony between fork and frame. Designing our own fork allowed us to avoid compromises where performance and aesthetics matter most.
The Fourth Generation
The Antenore A4 benefits from several important updates, many derived from the development path of the SB/04.
The rear dropouts are now 3D-printed using binder-jetting technology, improving alignment accuracy, stiffness, weight and visual coherence. The frame can be ordered with UDH compatibility.
As with all our models, the small but significant components are drawn and developed in-house. The CNC-machined T47 bottom bracket shell is produced from our own geometry, and the integrated seat clamp is equipped with titanium hardware. These details, though discreet, contribute meaningfully to the precision and identity of the frame.
Rim Brake Option
The Antenore A4 is offered exclusively as a disc-brake frame designed around electronic groupsets, reflecting the contemporary direction of performance road bicycles.
However, we continue to produce the Antenore A3 for those who prefer the, simplicity and aesthetic purity of rim brakes. The A3 is not a previous or outdated version, but a refined alternative for riders who value caliper brakes and the option of mechanical shifting. Both interpretations reflect the same approach to stainless steel craftsmanship.
A Frame for the Long Term
Each Antenore is built by hand in our workshop near Bergamo. Stainless steel provides natural resistance to the elements and allows for maintenance and repairs over time, contributing to a more sustainable approach to bicycle ownership.
Our intention is to create an object of lasting value, shaped slowly and with care, that remains reliable and enjoyable for many years of riding.
