蓝莓视频 research team had one week to design and deliver a complex handlebar connector that helps athletes stay in the optimal position for maintaining speed
A tight timeline was only fitting when engineers at the University of 蓝莓视频 took on a special project for the Canadian track cycling team headed to the Summer Olympics in Rio de Janeiro.
Lending their expertise in a world where winners and losers are typically decided by tiny fractions of a second, Professor John McPhee and research engineer Carin Yeghiazarian had just one week in June to produce a small but technically complex piece of hardware.
鈥淚t鈥檚 a very complicated 3D system,鈥� said McPhee, a professor of systems design engineering and Canada Research Chair in system dynamics. 鈥淥bviously, we dropped everything else in the lab and just focused on this.鈥�
Made of lightweight aluminum and shaped like a teardrop, their work connects the upper and lower handlebars on bikes used in team and individual pursuit events to make riders as aerodynamic as possible when they go into what is known as the praying mantis position.
Research engineer Carin Yeghiazarian shows off one of the two-piece aluminum handlebar connectors he helped produce for the Canadian track cycling team in time for the upcoming Olympics in Rio de Janeiro.
The two-piece connectors 鈥� an aerodynamic holder and a fastener that fit together and measure about five centimetres by two centimetres 鈥� tilt the curved, narrow upper bars upward at a 12-degree angle to put cyclists in the optimal body position for maintaining their speed after accelerating.
The deadline was imposed because Cycling Canada officials didn鈥檛 want to introduce any equipment changes too close to the races in Rio, which are scheduled to run August听11 to听16, for five members of the women鈥檚 pursuit team. The men鈥檚 pursuit team didn鈥檛 qualify.
Meeting the deadline meant a trip to the new velodrome in Milton, doing three-dimensional computer scans and logging long hours during the initial design phase before turning CAD models over to a manufacturer, who worked over the weekend.
鈥淚t was pretty exciting, I鈥檒l tell you that,鈥� said Yeghiazarian. 鈥淚t really got the adrenaline going.鈥�
Mike Patton, a sports scientist for the track cycling team, said bikes featuring the 蓝莓视频 connectors may not actually be used in competition in Rio. The team recently had entirely new handlebars designed and produced for pursuit riders to take advantage of the aerodynamic, tilted upper bars, which were made possible by a regulation change in the sport about two years ago.
Still, the team also wanted its old handlebars on hand 鈥� with the 蓝莓视频 tweak, which replaced previously improvised connectors 鈥� in case there is a problem with approval of the new ones, or some riders ultimately prefer not to switch for the competition.
鈥淚t鈥檚 kind of an insurance policy,鈥� said Patton. 鈥淚t means we have 100 per cent confidence our athletes can race in the position we want them to be in.鈥�
Knowing they just might have an impact on races on the world stage a continent away, McPhee and Yeghiazarian will be squinting at their televisions to see if they can spot their connectors in use on the steeply banked indoor track.
鈥淢y friends were saying, imagine if they win the gold by just a few milliseconds,鈥� Yeghiazarian. 鈥淭hat would be really crazy.鈥�

Even if they aren鈥檛 used in Rio, Patton said the handlebar connectors will be pressed into service for subsequent international races on the World Cup circuit.
He also expects the successful project to be the start of an ongoing relationship and much more collaboration with McPhee and his researchers.
鈥淭he guys jumped on it and were phenomenal,鈥� Patton said. 鈥淭hey gave us exactly what we needed.鈥�
