G2, 31.8mm Road & Gravel Stems

The Thomson G2 stem is a complete structural redesign of our popular X2 road stem. The G2 is stronger in all the right spots, without adding bulk. Machined from a single block of 7000 series aluminum, the G2 is lightweight and solid for any riding style — from fast road bikes to all-day gravel machines. Pair it with some Thomson bars for the entire cockpit collection.
