We produce bicycle frames and components that are both aero and incredibly light, stiff and precise, and both comfortable and absolutely thrilling to ride.


The Gram carbon frame was originally conceived by Alexandros Kitselis, a recognised advanced materials expert with a passion for cycling and an ambition to design and realise the best performance bike ever built.

Alexandros Kitselis spent 15 years perfecting design and manufacturing techniques inspired by Aerospace-grade technologies, initially through PhD theoretical and applied studies and through thousands of hours of prototyping.

The techniques perfected are the subject of patents pending. They depart from industry norms applying a uniquely different build approach.

The outcome of this work is a bicycle frame which is moulded in one single piece (a true monocoque) to the highest manufacturing and quality standards. Each frame is largely handmade. The techniques used require a long build cycle time relative to other manufacturers. The properties of the materials and this true monocoque design and build are simply unrivalled by any other bike manufacturer.

There is no gluing or bonding of tubes, no compensatory reinforcements required, no excess weight, no imbalances.


We are developing a range of core bicycle components using the most exacting standards and techniques in the cycling industry. Our components rival the very best for quality and results.   


Our road handlebars, the MARK SL,  are lighter than the lightest produced by industry leading manufacturers and super stiff.

Our road seat-post, the KION SL, is likewise the lightest on the market.   


Watch this space for further industry-leading components in the days and weeks to come.
