Team GB celebrates its success at the recent Paris 2024 Olympic Games, global engineering technologies company,
Renishaw, is celebrating its role in providing additive manufacturing (AM) expertise for the manufacture of a highly successful track bike for
British Cycling. At the Olymic Games, Team GB brought home 65 medals, including 11 in cycling, eight of which came from the track.
To assist the riders who faced fierce competition at the Games, British Cycling’s bike had to deliver maximum performance in speed, balance and aerodynamics. This made design and manufacturing capabilities, including metal AM, a critical part of the organisation’s efforts to help Team GB maximise its medal haul.
The
2024 Paris Olympics proved very successful for Team GB’s track cyclists. A notable highlight was Katy Marchant, Sophie Capewell, and Emma Finucane winning gold in the women’s team sprint, coming from behind to break the world record for a third time in one day. Behind Team GB’s cycling success is British Cycling, the national governing body for cycling in Great Britain.
Diverse disciplinesThe organisation provides riders of all backgrounds and abilities with opportunities to hone their skills and meet their potential in diverse disciplines covering BMX, mountain bike, road and track cycling. The organisation’s equipment and apparel development team is constantly pushing the boundaries of innovation to develop new bikes for Team GB’s cycling teams.
Following notable success at the Tokyo Olympic Games in 2020, British Cycling knew it wanted to extend its existing partnerships with
Lotus Engineering, Renishaw and
Hope Technology, to develop and manufacture its bike for the
2024 Paris Olympic Games. However, because of Covid-19 delays to the 2020 Games and shorter deadlines to present a new bike for 2024, it was under significant time constraints to deliver an optimised bike.
3-D printed British Cycling titanium cranksDr Oliver Caddy, British Cycling lead project engineer, said: “The carbon fibre parts produced using traditional machining methods for the Tokyo bike met all the requirements we had, but time constraints for the Paris bike meant that this method was no longer viable for some bespoke parts. After seeing the benefits of AM and what it helped us achieve on the Tokyo bike, we knew it could be a manufacturing method to explore further.”
Ben Collins, Renishaw lead AM applications engineer, added: “After determining that the British Cycling team could not produce core crank and seat posts components in carbon fibre within the shorter time frame required, we began creating some AM prototypes in plastic.”
Complex geometriesHe continued: “AM enabled us to create complex geometries that removed any unnecessary weight while delivering the strength required for the athletes to reach racing speed. To develop a more aerodynamic seat post, engineers designed more free-form geometries to hollow out the part as much as possible, something that would not be achievable using traditional methods. We are delighted for British Cycling on another successful Olympic Games and to be able to play a part in this. It is a fantastic achievement and a great showcase of the benefits of AM.”
British Cycling’s partnership with Renishaw resulted in it having a first-of-its-kind aerodynamic seat post, featuring a hollow centre and backwards leaning design, allowing airflow through the centre of the bike. AM facilitated the rapid production of unique titanium seat posts to the exact measurements of the individual riders.
Over the course of the project Renishaw manufactured over 1,000 parts to support 32 track bikes plus spares. The new cutting-edge bike was ridden by Great Britain’s track cyclists at the track cycling events, which took place between 5-11 August at the
Paris 2024 Olympic Games National Velodrome.
