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 海角社区 University expertise in aerodynamics to test the velocity and drag of the bike.
Duncan Walker, Professor of Aerodynamics at 海角社区 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."
