Introducing our latest project with Rocket at Rouleur Live 2026
Our collaboration with Rocket began in 2022 with 30 numbered editions based on our Rodano. For this second project, we turned to our flagship SB/04, giving it a full mirror-chrome finish inspired by the unmistakable shine of Rocket’s espresso machines.
Chrome is one of the most demanding finishes a frame builder can choose. It hides nothing: every weld, every junction and every detail must be right before the surface can reveal it. The result is a finish that puts the quality of the frame itself under the spotlight.
Under the chrome
The SB/04 Cromata is built around a custom Columbus tube set combining Spirit HSS, Life and Max tubing, TIG-welded in our workshop.
The frame features 3D-printed dropouts made using binder jetting technology and is paired with our Stelbel Evoluzione composite fork. Tyre clearance is up to 35 mm.
The Rocket influence also appears in the details: a circular graphic inspired by the drip tray of their espresso machines runs along the seat tube and chainstays, while a small model badge, hand-painted in the style of those on Rocket’s machines, sits on the left chainstay.
There is a shared history behind the choice of components, too. Most Stelbel frames that left our Milan workshop in the 1970s were built with Campagnolo components.
We have brought that connection into the present with Campagnolo’s flagship Super Record 13 Wireless groupset and Bora WTO 60 Ultra wheels.
The complete bike weighs 7.645 kg in size 54, without pedals.
The café stop
Rocket has long been connected to professional cycling, and we share with them something that goes beyond the products themselves: the café stop. A moment to pause, meet and talk about bikes over a good espresso.
See it in London
The SB/04 Cromata will make its public debut at Rouleur Live 2026, from 12 to 14 November, at the Bespoke Gallery in the Truman Brewery, London.
This made-to-measure edition will be available as a limited series, with orders opening on 12 November at 18:00 CET through a dedicated page on Rocket’s website. Each frame will be designed around the customer’s bike-fit report and a one-to-one conversation with our team, then built by hand in our workshop.
Rocket makes its machines by hand in Milan; we build our frames by hand in Bonate Sopra, near Bergamo. Different workshops, different products, but the same way of doing things.
Come and take a close look: chrome hides nothing.
