Bradley Wiggins will attempt to break the UCI Hour Record on a new Pinarello Bolide HR bike, which has been co-engineered by Jaguar and Pinarello.
The UCI-sanctioned Bolide HR track bicycle, which has been optimised for Sunday’s Hour Record based on Wiggins’ World Time Trial-winning Pinarello road model, possesses a one-piece titanium handlebar (3D printed) and frameset to ensure aerodynamic performance.
Sir Bradley Wiggins said: “The UCI Hour Record is the toughest challenge of human performance in cycling, where every fraction of a second matters.
“I’ve worked with Jaguar’s performance engineers since 2010, and their world class knowledge and experience in aerodynamics, combined with Pinarello’s expert frame building, gives me confidence that I can set a new standard on Sunday.
“The Bolide HR is the most aerodynamically efficient track bike I’ve ever ridden.”
The same CFD [Computational Fluid Dynamics] design methods used to develop the Jaguar XE, Jaguar’s engineers have applied their aerodynamics knowledge to help create an overall aerodynamic performance increase of 7.5%.
The Pinarello Bolide HR contains a completely re-designed one-piece handlebar system to optimise Wiggins’ interaction with the bike. Laser Sintering Technology has been applied to create a deeply re-shaped titanium handlebar, including the removal of the brakes, gear levers and an arm rest area designed to reduce air pressure and drag.
Jaguar and Pinarello have narrowed the fork design, making it closer to the front disc wheel, to enhance airflow in the bottom bracket area. Other key component changes from the Bolide road bike include the enhancement of the front fork surface, and re-shaping of the chainring and wheel hubs to optimise the bike’s aerodynamic capability.
Bradley Wiggins’ World Hour attempt will take place at the Lee Valley VeloPark in London on Sunday, June 7. We will be live streaming it here on CyclingTips.
