Full Speed Ahead NS ACR Stem

ACR stands for Aerodynamic Cable Routing. This stem is specifically designed to route your brake and shift cables internally through the stem and into the headset, which cleans up your cockpit and reduces aerodynamic drag.

Not necessarily. Because the ACR system requires specific cable routing through the headset and frame, it is designed to integrate with frames and headsets that support internal routing. You should verify that your bike's headset and frame are compatible with FSA's ACR or similar internal routing standards before purchasing.

Yes, as long as your handlebars have a 31.8mm clamp diameter. However, to get the full benefit of the internal cable routing, you will ideally want handlebars that also support internal cable routing, allowing the cables to pass through the bar and directly into the stem.

6061 T6 alloy is a standard choice for high-performance stems because it provides excellent stiffness-to-weight ratio. It offers a very rigid, responsive feel when sprinting or climbing, ensuring your steering inputs are direct and precise.

A -6 degree angle is a standard, neutral-to-aggressive position for most road and gravel bikes. It provides a balanced aerodynamic profile that works well for riders looking to achieve a performance-oriented posture without being overly slammed.

Yes, the included spacers are essential for the ACR system to function correctly. They are designed to bridge the gap between the stem and the headset while maintaining the internal cable routing path, ensuring a seamless and secure fit.
