At the core is a lightweight ALUXX-grade aluminium frame, built with endurance-focused geometry that positions you more upright for improved confidence and visibility in traffic. The Advanced-grade composite fork with OverDrive tapered steerer delivers stiffness and steering precision, perfect for navigating fast descents or rougher lanes.
The bike rolls on Giant’s SR-2 alloy wheels, shod with 700x40c Gavia Fondo AR tubeless tyres, offering great grip, stability and the freedom to venture off the beaten path. With tubeless compatibility and high-volume casing, they also absorb vibrations and reduce the risk of punctures.
For gear changes, the Shimano CUES 11-speed drivetrain is both smooth and robust, featuring a wide-range 11–45T cassette that’s ideal for tackling hills without fuss. Paired with a durable FSA Omega 42T crankset, it gives you balanced gearing for fast flats and low-effort climbing alike.
Hydraulic disc brakes from Tektro give you dependable stopping power in any conditions, while comfort comes courtesy of Giant’s D-Fuse composite seatpost and the ergonomic ErgoContact saddle, designed to soak up road buzz and keep you riding longer.
Occasionally, without notice, manufacturers change product design and/or specifications.
