FSA

Non-Series ACR Stem

What Our Gearhead® Experts Are Saying:

"I’ve installed this stem on a few integrated road setups, and it’s one of the cleanest cable-routing solutions out there. The ACR system makes the cockpit look super tidy, and the stiffness is noticeable when you’re wrenching on the bars during hard accelerations. It is on the heavier side, but the build quality, finish, and routing integration make it a solid choice for modern aero frames."

We turn to the FSA Non-Series ACR Stem when we want a streamlined cockpit that matches the modern road aesthetic—sleek, stiff, and seamlessly organized. Built around ACR—Aerodynamic Cable Routing—it’s designed to fully conceal brake hoses and shift housing through compatible bars, headsets, and frames, giving our road bike a wind-cheating, ultra-clean front end that feels as fast as it looks.

The forged 6061-T6 aluminum body keeps steering precise and responsive, even when we’re putting down power on climbs or sprinting out of corners. Chromoly hardware ensures long-term durability, while the included spacers help dial in stack height without interrupting the integrated look. From the bead-blasted anodized finish to the low-profile frontal shape, every detail reinforces the stem’s purpose: maximizing performance while elevating cockpit aesthetics on modern road builds.
