Giant TCR Aero Philosophy

Giant’s Compact Road design is arguably one of the most important developments to hit the peloton since Lycra. So significant is the design that the Union Cyclist International (UCI) was forced to change their rules regarding frame configuration. And bike makers, from the most respected European custom builders to the largest companies in the world, have adopted the design.

By sloping the top tube downward toward the rear of the bike, two very important characteristics were achieved. First, the frame became stiffer for improved acceleration and more solid cornering. Second, the bike got lighter.

But what makes Giant’s Compact Road geometry truly superior is that only four frame sizes are needed to achieve a custom fit, for virtually every size of rider. Giant’s designers have found that only four “ranges” of frame size are necessary, with the final fit being determined by the saddle height and handlebar stem reach and height. This eliminates the need for creating several frame sizes in small millimeter increments.
