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 91²Ö¿â expertise in aerodynamics to test the velocity and drag of the bike.
Duncan Walker, Professor of Aerodynamics at 91²Ö¿â, 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."
