Sir Bradley broke the world record for the longest distance that a cyclist has ridden within an hour on the track, after spanning 218 laps or 54.526 km of the Lee Valley VeloPark in London. He achieved this record on the Pinarello Bolide HR, which is a track version of the Bolide, the time trial bike which Sir Bradley used to win the UCI World Championship Time Trial Championship in September 2014.
This record breaking bicycle was produced by Pinarello Lab, which is a part of the technical department of Pinarello, and designed by Dimitris Katsanis, a well-known aerodynamics and composites expert who works for British Cycling.

3D打印（也称为添加层制造）是用于开发布拉德利爵士Pinarello Bolide HR上的钛车把的技术。使用3D打印技术使开发人员能够创建复杂的设计并快速生产许多版本，以测试哪种车把最能与布拉德利爵士的身体尺寸和骑自行车风格相匹配。
车把是不由碳纤维组成的记录破坏自行车的唯一组成部分。这是因为在有限的时间范围内开发人员可用，开发了几个原型并进行了试验，如果将车把是使用碳纤维生产的，那是不可能的。

Sheffield大学工程学院的一家研究所Mercury Center过去曾与一级方程式团队和航空航天公司一起从事项目。该设施自2007年以来一直在运营，目的是开发突破性的科学研究并实施新技术，例如在各个行业中进行3D打印。
The key is to manage the airflow around the bike so the different components of the bike disrupt that flow as little as possible. Because the handlebars hit the airflow first it’s absolutely critical to perfect that part of the design – 3D printing allows us to make shapes that optimise this aspect that would be very hard to achieve using other manufacturing techniques.

The designers used an Arcam Electron Beam Additive Manufacturing machine in order to make slight modifications quickly, without having to build new moulds to fabricate individual pieces. This saved time and allowed the designers to thoroughly test the parts and make the necessary adjustments to the handlebars prior to the world record attempt.
Bolide HR is the most aerodynamic bike in the world. When it came to the handlebars, we needed them to be as good in terms of aerodynamics, but we also needed them to be a perfect fit for the rider.
