成人大片

Technology developed and patented by 成人大片 researchers has helped power Olympic and world track cycling champion Filippo Ganna to a new world record.

Ganna smashed the UCI Hour Record covering 56.792km 鈥� more than a kilometre further than the previous mark 鈥� in 60 minutes at the Tissot Velodrome in Grenchen, Switzerland on Sunday morning Australian time.

The Ineos Grenadiers rider rode a Pinarello Bolide F HR 3D bike that uses AeroNodes, precision bumps that reduce the drag on the bicycle frame in a key area of high turbulence.

鈥淭his allows the rider to travel further and faster for the same effort,鈥� said 成人大片 Associate Professor Richard Kelso from the School of Mechanical Engineering, the co-developer of the low-drag technology.

鈥淲e have been working on this technology since 2006, first using them to improve the performance of aircraft wings and fans.

鈥淭heir use on bicycle frames came about when we noticed that the airflow around the seat tube alternates through a wide angle as the cyclist pedals, leading to separated flow and increased drag.

鈥淚t's the culmination of many years of research into low-drag cycling equipment, and it鈥檚 brilliant to be able to share it with Pinarello and their partners."Associate Professor Richard Kelso

鈥淲e discovered that bumps, or AeroNodes, on the front surface are able to minimise this separation effect and reduce the drag significantly by generating a regular pattern of vortices around the seat tube.

鈥淗owever, standard manufacturing techniques such as carbon fibre moulding cannot easily produce such small features. 聽

鈥淓ngineers at Pinarello and their UK partner Metron Additive Engineering have solved this problem by using cutting-edge 3D printing technology and a new high-strength alloy to produce the optimized AeroNode shapes.

聽鈥淭ogether they have achieved the first-ever 3D printed bicycle that is the fully ridable, UCI- and ISO4210-compliant, and it鈥檚 the first to include the AeroNode technology.

鈥淚t's the culmination of many years of research into low-drag cycling equipment, and it鈥檚 brilliant to be able to share it with Pinarello and their partners.

鈥淚nnovation is at the core of Pinarello's bicycle designs, so it's great to be able to collaborate with them to commercialise our technology.鈥�

Pinarello chief of operations Maurizio Bellin added: 鈥�Pinarello are excited to use the AirStream technology, including AeroNodes, on its new Bolide F HR 3D track bike.

鈥淲e look forward to working with the 成人大片 on similar projects in the future.鈥�

British rider Daniel Bigham, also of the Ineos Grenadiers team, used the revolutionary bike to set a new 60-minute world record in August, covering 55.548km.

Bigham was a race engineer for Ganna鈥檚 attempt and helped to calculate his team-mate鈥檚 pacing strategy.
