Full Speed Ahead SMR ACR Stem

Yes, the SMR ACR stem is designed to accommodate both mechanical and electronic setups, as well as hydraulic braking systems, by routing cables directly through the cockpit.

Yes, it features a standard 31.8mm handlebar clamp diameter, making it compatible with the vast majority of modern road and gravel handlebars.

Because the cables are routed internally through the stem and into the frame, maintenance like replacing housing or brake lines is more involved than with an external setup. You will likely need to disconnect your lines to perform these swaps, so it is best suited for riders comfortable with more complex bike mechanics.

The oil slick finish is applied to the 3D-forged and CNC-machined aluminum, providing a unique aesthetic that is as durable as standard anodized finishes. Like any high-end finish, it will hold up well to normal riding conditions, though it can show scratches if subjected to abrasive impacts.

While you can physically mount the stem, its primary purpose is to facilitate internal cable routing. If your frame and headset are not designed to accept cables through the headtube area, you will not be able to take advantage of the 'clean' cockpit look this stem is engineered to provide.

This stem has a stack height of 33.5mm. You should measure your current stem's stack height to ensure it matches or adjust your headset spacers accordingly to maintain your preferred handlebar position.
