Vástago FSA ACR de 6 grados

The FSA NS ACR Stem -6 Degree is a precision-engineered road stem designed for riders who want aerodynamic efficiency, solid strength, and clean cable integration. It features the Aerodynamic Cable Routing (ACR) system, allowing brake and shift cables to pass cleanly through the stem for reduced frontal drag and a neater cockpit setup.

Made from 6061-T6 aluminum with chromoly hardware, this stem balances performance and durability. The -6° angle provides a lower front-end position for aggressive riding, and it is available in multiple lengths to suit rider geometry and style—from tight, compact setups to larger reach builds.
