FSA SMR ACR Stem

The FSA SMR ACR stem is designed for bikes that support internal cable routing through the headset. While it fits a standard 1-1/8 inch steerer tube, your frame must be compatible with the ACR (Aero Cable Routing) system to actually route the cables through the stem and into the headtube.

Yes, as long as your handlebars have a 31.8 mm clamp diameter. However, for the cleanest look and easiest cable management, you may want to pair this with bars that have internal routing ports, though it is not strictly required.

A -6 degree angle provides a slightly aggressive, performance-oriented position that is standard for most modern road and gravel bikes. It offers a good balance between aerodynamics and comfort, keeping your front end low without being overly extreme.

It is built for both. The alloy construction is durable enough to handle the vibrations and varied terrain of gravel riding, while the internal routing helps protect your cables from dirt and debris.

It does add a step to the process. Because the cables run through the stem, you will need to disconnect them if you plan to change the stem height or swap the stem entirely, which can be more involved than with a traditional external setup.
