Tech Highlights

Show Highlights

1

COMPLIANCE TUNED TECHNOLOGY

Specific composite layup and tube shaping, including ultra-thin and flattened seatstays, a low seatstay/seattube junction, and thin, slightly curved fork legs combine for a balanced, compliant ride quality and reduced rider fatigue.

2

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.

3

OVERDRIVE 2

Designed to offer unprecedented 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.

4

INTERNAL CABLE ROUTING

Frame features unique internal cable porting for sleek, uncluttered appearance and performance.

5

D-FUSE SEATPOST

The proprietary “D” shaped composite seatpost dampens vibration—resulting in a smooth, compliant ride.

6

ADVANCED-GRADE COMPOSITE FORK

A fork and steerer tube constructed entirely using Giant’s Advanced-grade composite for lightweight and superior ride quality and steering precision.

7

DISC-BRAKE INTEGRATION

Frame is engineered with flat-mount disc brake integration for superior braking performance in all weather and road conditions. 

8

THRU-AXLE DESIGN

All-new 12-millimeter thru-axles front and rear provide superior braking performance and stiffness for precise cornering and overall road control. 

The Advanced-grade composite frame features endurance geometry with the perfect blend of light weight, stiffness and road-smoothing compliance. The OverDrive 2 steerer tube and full composite fork work together to boost front-end stiffness and precision. Disc brake technology with 12mm front and rear thru-axles gives you total control, even on rough roads and poor conditions. The D-Fuse seatpost smoothes out road vibrations, and the PowerCore bottom bracket turns every pedal stroke into positive forward motion.
