At Eurobike 2013, Giant has launched a fresh set of bikes within the relatively new Propel aero road bike family. Following on the heels of the Propel Advanced SL, the Propel Advanced has many of the design features of its older brother but in a less expensive and more adjustable package.
There are three models in the Propel Advanced line – the 1 has 11-speed Shimano Ultegra Di2 and Giant P-SLR aero wheels; the 2 gets mechanical 11-speed Shimano Ultegra and P-SLR aero wheels; the 3 uses a Shimano 105 group and Giant P-A2 wheels. Pricing varies by market.
Giant spent two years creating the Propel Advanced, which includes hidden aero brakes in addition to a slippery frame. Because a rider affects the aerodynamics of a bike, and vice versa, Giant used a moving mannequin for its wind tunnel testing, going through a claimed 88 prototypes before settling on a design.
Giant calls its new aero integrated brakeset Speed Control SL. The front caliper mounts behind the fork, as is the current trend with many time trial and triathlon bikes, and the rear brake sits on the seatstays.
While the Propel Advanced SL has an integrated seatmast, the new bike has an adjustable aero seatpost.
