We look for the perfect solution in every step of our work in order to make sure that every detail conforms to the customer requirements.



High-End Frame Development

Carbon and Aluminium

We engage in a joint process with our customers to develop the ideal bike frame – from the first draft to the finished product. Our engineering teams for carbon and aluminium frames ensure the best possible workflow and enable the precise implementation of individual parameters and requests.



Paintwork & Assembly

Thanks to paint shops that are ready to handle any materials and demands (even silver-plated carbon), we can deal with all imaginable requirements in a flexible way.

Our manufacturing processes are efficient and versatile, and they fulfil the highest of demands, even “100% ready-to-ride”.
