A fully custom 3D-printed bike, offering fully additively manufactured, aerodynamically optimised and CFD-tested titanium, has been unveiled at Rouleur Live bike show in London.
The bike is made entirely by additive manufacturing, allowing a precise fit to a rider’s geometry. Printed in three different parts, and then welded together, it is hoped the bike, named 'Speedform', will pave the way for the future of the cycling industry.
J.Laverack, the Rutland-based company behind the bike, used Loughborough University expertise in aerodynamics to test the velocity and drag of the bike.
Duncan Walker, Professor of Aerodynamics at Loughborough University, collaborated with the bike manufacturer for computational fluid dynamics testing.
Working in collaboration, the study compared Speedform to J.Laverack’s existing R J.ACK Disc model bike and found a 20–26% reduction in aerodynamic drag between 30–48 km/h.
Professor A. Duncan Walker said: “The CFD analysis clearly demonstrated that J.Laverack’s new aero frame achieves a substantial aerodynamic benefit over conventional round-tube designs.
“At typical road cycling speeds, this equates to drag reductions of 20–26%, or savings of up to 17 watts — impressive gains achieved through intelligent design and advanced additive manufacturing.”
Key design highlights of the bike include:
- Dropped seat stays for aerodynamic advantage and stiffness
- Internal cable routing and T47 bottom bracket
- Optimised for 30mm tyres, compatible up to 32mm+
- Additively manufactured KT1 seatpost and optional integrated stem
Each frame is custom-built using parametric design, allowing J.Laverack to tailor geometry precisely to each rider’s needs — a bespoke approach impossible in mass-produced carbon frames.
“Speedform is a statement of what’s possible when additive manufacturing meets craftsmanship,” says Oliver Laverack, Co-founder. “It’s elegant, efficient, and engineered for pure speed.”

About Loughborough University
Loughborough is one of the country’s leading universities, with an international reputation for research that matters, excellence in teaching, strong links with industry, and unrivalled achievement in sport and its underpinning academic disciplines.
It has been awarded five stars in the independent QS Stars university rating scheme and named the best university in the world for sports-related subjects in the 2025 QS World University Rankings – the ninth year running.
Loughborough has been ranked seventh in the Complete University Guide 2026 – out of 130 institutions.
This milestone marks a decade in the top ten for Loughborough – a feat shared only by the universities of Oxford, Cambridge, LSE, St Andrews, Durham and Imperial.
Loughborough was also named University of the Year for Sport in the Times and Sunday Times Good University Guide 2025 - the fourth time it has been awarded the prestigious title.
In the Research Excellence Framework (REF) 2021 over 90% of its research was rated as ‘world-leading’ or ‘internationally-excellent’. In recognition of its contribution to the sector, Loughborough has been awarded eight Queen Elizabeth Prizes for Higher and Further Education.
The Loughborough University London campus is based on the Queen Elizabeth Olympic Park and offers postgraduate and executive-level education, as well as research and enterprise opportunities. It is home to influential thought leaders, pioneering researchers and creative innovators who provide students with the highest quality of teaching and the very latest in modern thinking.
