FSA SMR ACR Stem

The SMR (Smart Cable Routing) system allows you to route your brake hoses and shift cables internally through the stem and into the frame. This creates a cleaner, more aerodynamic cockpit by hiding the cables that would otherwise be exposed.

This stem is compatible with any standard handlebar that features a 31.8 mm clamp diameter, which is the most common size for modern road and gravel bikes.

Yes, the SMR system is designed to accommodate both electronic and mechanical shifting setups, as well as hydraulic and mechanical braking systems.

A 6-degree angle is a standard rise for road stems. Depending on whether you flip the stem up or down, it will provide a slightly more upright or aggressive riding position, helping you fine-tune your fit.

This stem has a stack height of 33.5 mm. You should ensure your steerer tube has enough length to accommodate this specific measurement, or you may need to adjust your headset spacers accordingly.

Absolutely. The stem is constructed from 3D forged and CNC-machined 6061 aluminum, which provides a high strength-to-weight ratio suitable for the rigors of road and gravel cycling.
