The Thomson G2 stem is a complete structural redesign of Thomson’s X2 road stem, engineered to increase strength in key stress areas without adding bulk. Machined from a single block of aerospace-grade 7000 series aluminum, it’s designed to deliver a lightweight, solid cockpit connection for road and gravel riding, with fit options that let you fine-tune comfort, performance, and control over long miles.
