Giant Contact SLR Aerolight Stem

No, this stem is designed exclusively for Giant's OverDrive Aero steerer tubes. It will not fit standard round steerer tubes, so please verify your bike's specific steerer type before purchasing.

The stem is specifically engineered to work with Giant's Contact Aero and D-Fuse handlebars. It features a 31.8mm clamp diameter, but the internal cable routing system is optimized for these specific aero-profile bars.

The 100mm version weighs 123g. While the exact weight savings depend on your current setup, its primary advantage is the combination of a lightweight composite construction and aerodynamic cable integration, rather than just raw weight reduction.

Yes, the -10 degree angle provides a more aggressive, lower position compared to standard stems. If you are currently using a stem with a different angle, you may need to adjust your spacer stack or fit to maintain your preferred reach and drop.

The system is designed for intuitive cable management, but it does require routing your brake and shift lines through the stem and into the steerer tube. If you are comfortable with hydraulic brake bleeding and internal routing, it is straightforward, but it may be more complex than a traditional external-routing stem.
