Stelbel x Rocket
SB/04 Cromata
A full-chrome steel race bike built around Campagnolo Super Record 13 Wireless and
Bora WTO 60 Ultra wheels, dressed in the mirror shine of a Rocket espresso machine.

A Shared Language
Rocket and Stelbel renew their collaboration with the SB/04 Cromata, a made-to-measure steel race bike that brings together Italian framebuilding expertise and Rocket’s distinctive design. Finished in mirror chrome, it reflects the two companies’ shared appreciation for craftsmanship, performance and attention to detail. It is built around Campagnolo’s flagship Super Record 13 Wireless groupset and Bora WTO 60 Ultra wheels.
The Bike
The SB/04 is Stelbel’s flagship and its most race-oriented model. It is stiff and efficient, yet keeps the best of steel: a ride that always feels intuitive and rewarding, pairing performance with comfort. For this edition it wears a full chrome finish, the same mirror shine as a Rocket machine, hence the name Cromata. The graphics borrow from Rocket’s visual language, including the grid of circles found on the drip tray of every Rocket machine, which appears on the seat tube and chainstays. For the SB/04 Cromata, Campagnolo supplies its flagship Super Record 13 Wireless groupset and Bora WTO 60 Ultra wheels with a power meter as an option.
The finishing touch sits on the left chainstay: a small model badge, hand-painted in the classic style of the badges on Rocket’s machines. The badge that names a Rocket espresso machine now names a bike.



Two Worlds, United by Coffee and Cycling
Rocket’s role in this project comes from two places. The first is cycling: coffee and cycling share a ritual, the café stop, and Rocket has been part of professional cycling for years, through partnerships with many of the sport’s leading teams and riders.
The second is Stelbel itself. The two companies have known each other for years and work the same way: in workshops where experienced hands still shape the metal, with the same care for detail, craft and design.
The purchase price of the SB/04 Chrome starts at €13,440.00, excluding VAT. For further information, please fill out the form below.
