UPDATED: Wiggins breaks hour record on Pinarello

CHARLOTTE, N.C. (BRAIN) — British pro rider Bradley Wiggins broke the UCI Hour Record this weekend on a Pinarello Bolide HR bike co-engineered by Jaguar and Pinarello. 

Wiggins set a new record of 54.526 km before a full-to-capacity London Lee Valley VeloPark Velodrome. Wiggins beat the previous record, set by fellow Briton Alex Dowsett on May 2 in Manchester, by 1,589 meters. 

The UCI-sanctioned Bolide HR track bike Wiggins rode featured a one-piece titanium handlebar and frameset for aerodynamic performance. The same Computational Fluid Dynamics design methods used to develop the Jaguar XE, the most aerodynamic car Jaguar has produced, were part of a comprehensive study for the development of the Bolide frame.

The Pinarello Bolide HR has a completely redesigned one-piece handlebar system. Laser Sintering Technology was used to create a deeply reshaped titanium handlebar, including the removal of the brakes, gear levers and an innovative armrest area to reduce air pressure and drag.

Jaguar and Pinarello narrowed the fork design, making it closer to the front disc wheel, to enhance airflow in the bottom bracket area. Other key changes from the Bolide road bike include the enhancement of the front fork surface, and reshaping of the chainring and wheel hubs to improve aerodynamics. Overall, engineers were able to increase aerodynamic performance by 7.5 percent, according to Pinarello and Jaguar.

Pinarello has a long-standing affiliation with the Hour Record, most notably in 1994 when the Italian bike manufacturer developed the Pinarello Espada for Miguel Indurain during his successful record attempt.

“I’m extremely honored to be involved in creating this special Bolide HR for Bradley’s Hour Record challenge, 20 years after the last model we designed for Miguel Indurain,” said Fausto Pinarello, CEO of Pinarello. “Our relationship with Bradley, as well as Jaguar during our years as fellow partners of Team Sky continues to ensure Pinarello are creating world class, high performance bikes.”

“I am really glad it’s done," Wiggins said after the attempt. “This is as close as I’ll get to know what giving birth feels like. It is torturous; you never think it is going to come to an end.

“I am just really glad it’s done, the build-up was long since Paris-Roubaix. My wife and children know more than anyone about air pressure. I am glad to be in the company of these greats, Rominger, Indurain ...”
