When introduced by Giant in 1990s, Compact Road revolutionized the look and feel of high-performance road bikes forever. A downward sloping toptube (from the headtube to the seattube) creates smaller front and rear triangles for a lighter, stiffer bike. It also makes it easier for riders of all sizes to have a perfect fit.
A massively oversized bottom-bracket/chainstay area features a fully integrated, 86-millimeter wide bottom-bracket design (92-millimeterwide for off-road bikes). Asymmetric chainstays provide additional stiffness on the driveside and stability on the non-driveside.
The most advanced steerer tube technology in today’s Liv and Giant bikes. Designed to offer unprecedented front-end steering performance, the system’s oversized headset bearings (1 1/2” lower, 1 1/4” upper) and tapered steerer tube work in harmony to provide supreme steering stiffness.
Liv and Giant’s chainstay-integrated, wireless data transmitter. The removable transmitter sends wheel speed and cadence information directly to any ANT+ compatible computer.
