OverDrive 2

Giant’s all-new oversized fork steerer tube technology. Designed to offer unprecedented front-end steering performance, the system’s oversized headset bearings and tapered steerer tube work in harmony to provide supreme steering stiffness.

Modified Monocoque Construction

Similar to Monocoque technology, but Modified Monocoque eliminates the outermost woven composite sheet (found on heavier framesets) to reduce weight without affecting ride quality, strength or stiffness.

PowerCore

A massively oversized bottom-bracket/chainstay area features a fully integrated, 86-millimeter-wide bottom-bracket design. Asymmetric chainstays provide additional stiffness on the driveside and stability on the non-driveside.

MegaDrive

A massive rectangular downtube and oversized toptube work in unison to provide superior front-end lateral and torsional steering precision. The precisely engineered, rectangular shaped downtube yields unprecedented pedaling stiffness.

Vector Seatpost

This full-composite, lightweight (210 grams) and highly aerodynamic seatpost is engineered specifically for the unyielding demands of the performance-minded road rider. It offers increased fore/aft stiffness for maximum energy transmission, improved aerodynamics (compared to a traditional round seatpost) and two offset options (10 or 23 millimeters).

Tuned Composite

Hand-cut composite swatches are strategically laidup, piece by piece, to create each frame. The frame’s ride qualities are meticulously crafted and controlled through precise layering of each individual swatch (there are more than 500 pieces per frame) in an exact schedule. The direction of each individual piece’s composite grain allows Giant engineers to customtune each frame’s individual ride characteristics.

RideSense

Giant’s all-new chainstay integrated, wireless data transmitter. The fully integrated, removable transmitter sends wheelspeed and cadence information directly to any ANT+ compatible computer.

WeightThe most accurate way to determine any bike’s weight is to have your local dealer weigh it for you. Many brands strive to list the lowest possible weight, but in reality weight can vary based on size, finish, hardware and accessories. All Giant bikes are designed for best-in-class weight and ride quality.
