This high-performance stem is engineered for riders who demand precision, stiffness, and the ability to fine-tune their setup for any trail.

The Tharsis 3Five stem is purpose-built to integrate seamlessly with the Tharsis 3Five range of bars. The foundation of its superior performance lies in its oversized 35-millimetre clamping diameter.
