By effectively sloping the toptube downward toward the seatstays, Giant was able to reduce the overall size of the front and rear frame triangles, resulting in the now-distinctive compact layout. Functionally, the compact configuration reduces weight and increases lateral rigidity. As a result, the frame accelerates faster thanks to less energy loss through unwanted flex. Stiffer is more efficient, but it doesn’t always offer the most comfortable ride. To address this, Giant engineers are careful to include just the right amount of vertical compliance (a good thing) into each Compact Road Design for increased forgiveness and control. A full range of sizes (up to seven in some series) assures that riders of every size can find their ideal fit.
