If you are a major bike manufacturer and have developed new technology to make your product faster \u2013 and therefore more attractive to serious amateur cyclists \u2013 there is no better \u2018billboard\u2019 in the world than the Tour de France. In this year\u2019s Tour, the word on everyone\u2019s lips was aero<\/em>, because major brands, such as Cannondale, Trek and Specialized, introduced their new, aero framesets in the race.<\/strong><\/p>\n

Aero road bikes are not new \u2013 they\u2019ve been available for more than a decade. Their original aim was to go as fast as possible in a straight line, thereby, however, sacrificing control and comfort. But with a UCI minimum bike weight limit of 6.8 kg, racers and the companies that build their bikes had to look beyond reducing grams to gain extra speed \u2013 which meant producing a racing bike that integrated aerodynamics with handling and ease of use. In any case, there is a growing belief in the sport today that reducing wind drag is more important than losing weight.<\/p>\n

Specialized Venge 2019<\/figcaption><\/figure>\n

The fact that reigning road race world ch<\/span>ampion and five-time green jersey winner Peter Sagan rode the brand new Specialized Venge 2019 in the Tour drew a lot of attention. Specialized claims that \u201caerodynamic optimization is the most important thing we can do to make you faster\u201d. To that end, it says that it used optimization software to create a \u2018library\u2019 of \u201cthousands of tube shapes and analysed them based on aerodynamics, surface area, and stiffness\u201d, resulting in the Venge 2019.<\/p>\n

The Venge\u2019s new frameset and modular cockpit were redesigned to reduce drag, with a new stem, dropped handlebar clamp and cables hidden beneath the stem and blocked from the wind by the handlebars. In addition, the bike\u2019s head tube and fork were also redesigned for better aerodynamics, without \u2013 the company says \u2013 sacrificing stiffness in handling. And the bike is 460 grams lighter than its previous version. So, it was little surprise that Sagan won three Tour stages and easily claimed a sixth green jersey, to tie Germany\u2019s Erik Zabel for the most points classification wins in Tour de France history.<\/p>\n

The Cannondale SystemSix was also officially launched in the Tour de France run-up, with the company claiming that it is the fastest UCI-approved road bike in the world. Like the Venge, the SystemSix uses only disc brakes and features some classic aerodynamic features, such as lowered seat stays, shorter aero tubing and a fork crown that is integrated virtually seamlessly into the down tube. The SystemSix also has a chine on the down tube that, Cannondale says, redirects an upward flow of air from the back of the fork leg and channels it downstream, preventing it from interfering with the flow over the fork crown and head tube.<\/p>\n

Cannondale also invested a great deal of research into the wheels. As the company says, \u201cSince the front wheel is the leading edge of the whole bicycle, it sees the cleanest airflow. Therefore, it was is an important starting point for aerodynamic optimization.\u201d Its HollowGram KN\u00d8T64 wheel\u2019s wide profile enables the air flow from a wide tyre to cleanly \u201creattach\u201d to the rim, thereby reducing drag. The shape of the wheel\u2019s rim allows cyclists to run a large, 28mm tyre, with minimal increase in drag compared to a smaller, 26mm tyre.<\/p>\n<\/lite-youtube>\n

Although it boasts an aerodynamically advanced bike model, the 2019 Propel Advanced Disc, the world\u2019s largest bike manufacturer, Giant, did not introduce it at the 2018 Tour de France. The company says the Propel\u2019s tube shapes were designed using wind tunnel data as well as computational fluid dynamics (CFD), which employs numerical analysis to solve fluid-flow problems and simulate the interaction of liquids and gases with boundary-defined surfaces.<\/p>\n

An important aerodynamic feature of the Propel is a truncated ellipse aerofoil shape that is designed to reduce drag at a wider range of wind angles than traditional teardrop-shape frame tubing. In addition, the bike\u2019s composite SLR AeroWheelSystem features different rim depths on its front and rear wheels \u201cto minimize drag without compromising stability\u201d, the company says. Aerodynamic gains were also a priority in the design of the bike\u2019s seat post, handlebar and stem. For anyone interested in the research that goes into designing a Tour de France superbike, a look at the \u2018SystemSix White Paper\u2019 on the brand\u2019s website<\/a> should be illuminating \u2013 and go a long way to explaining why these racing bikes carry a price tag of $11,500 and more.<\/p>\n","protected":false},"excerpt":{"rendered":"
