The Giant Contact Switch AT dropper seatpost is designed for riders who want maximum saddle height and confidence in technical terrain without compromising control. It allows for easy reduction of the base travel by up to 30 mm tool-free, and thanks to its refined construction, it can be inserted deeper into the frame, making it ideal even for smaller frames.

The rotating cable actuation mechanism and reduced clamp height help find optimal cable routing while maximizing seatpost insertion. The modular 3-in-1 lever is compatible with various mounting systems, allowing you to easily integrate the seatpost into your existing cockpit. 7075 aluminum alloy, lower weight compared to older models, and a replaceable internal cartridge ensure reliable function and easy servicing.
