The wind is one of the toughest opponents on a road bike. Aerodynamics is the magic word. But a wheel doesn't just have to be aerodynamic. Weight, stiffness, and comfort are also important. Only when all parameters are balanced is a wheel perfect. The BITURBO Aero, introduced in 2020, was developed with precisely this focus in mind. Now we present the Aero 2.0, its lightning-fast successor. The wheel set has been completely redesigned. It is even lighter and more aerodynamic. Wind tunnel tests prove the performance gains. The advantage is measurable.
The 48.5-millimeter-high rim has a special shape. This makes even more effective use of the so-called sail effect in crosswinds. The forward propulsion is higher when there is a side wind. This means that the speed increases with the same amount of force. The effect was confirmed in comparative tests in the wind tunnel. The difference to the BITURBO Aero is a noticeable 7 watts at 45 km/h and a 10-degree angle of attack. We worked with renowned experts from Bike Engineering to evaluate the wind tunnel data.
Aerodynamics was only one criterion during development. Weight was also important. Lighter is always possible. But maximum lightweight construction alone does not make a good wheel. The focus of the BITURBO Aero 2.0 is therefore on the stiffness-to-weight factor. Weight and stiffness are in an optimal ratio. This guarantees perfect riding characteristics. This applies to hard pedaling as well as fast cornering. The stiffness-to-weight ratio was optimized with a new, innovative carbon layup, among other things. The weight of the wheel set was reduced to 1344 grams without compromising lateral stiffness. The front wheel weighs 624 grams, the rear wheel 720 grams.
The BITURBO Aero 2.0 is optimized for tires with a width of 28 to 30 millimeters. The hooked rim measures 32.5 millimeters at its widest point on the outside. The inner width is 23 millimeters. The carbon layers are designed to filter out road shocks to a certain extent. This provides comfort and safety. Practical: the special design of the rim bed eliminates the need for tubeless sealant tape.
The wheels are handmade in our factory. The high quality of workmanship makes it possible to dispense with paint. This saves weight. A complex finishing process gives the BITURBO wheels their typical matt, shimmering carbon look. The surface is sealed and scratch-resistant. The wheels feature original hub technology from DT Swiss. The BITURBO Aero 2.0 is available with freehubs for Sram, Shimano, and Campagnolo.
