Key Performance Factors

Lightweight Efficiency

Advanced Composite frameset and sleek tube shaping make this model 350g lighter than the aluminium version. A stiffer bottom bracket improves power transfer, helping you accelerate and climb with less effort.

Smooth, Stable Ride Quality

Flat-bar frame geometry puts you in a confident upright riding position. Paired with powerful disc brakes, a D-Fuse composite seatpost, and ErgoContact saddle, the ride stays smooth and controlled even on rougher surfaces.

All-Road Capabilities

High-volume 40mm tubeless tyres add versatility and grip, giving you the freedom to explore paved roads, gravel paths, or urban shortcuts with ease.

TECHS & FEATURES

×

ADVANCED COMPOSITE TECHNOLOGY

Giant’s High Performance Grade raw carbon material is used to produce this custom frame material in our own composite factory with a high stiffness-to-weight ratio. The front triangle of these framesets is assembled and moulded as one continuous piece in a proprietary manufacturing process called Modified Monocoque Construction.

TUBELESS SYSTEM

Fewer flat tyres. Greater traction. Less rolling resistance and a smoother, faster ride. Giant’s Tubeless System makes it easier than ever to experience all these benefits.
