FSA Metron ACR 3mm Low Stack spacer

Description

When you’re dialing in your road fit down to the last detail, even millimeters matter. FSA Metron ACR 3mm Low Stack tapered spacer Matt Black helps you match your integrated handlebars to the frame cleanly and without compromise.

Main benefits

This tapered spacer for the ACR system makes it easy to fine-tune cockpit height precisely, so the handling feels natural and confident. It’s ideal both when building a new bike and for subtle adjustments after a service.

Thanks to a shape designed for specific frame types, it creates a smooth transition between the head tube area and the integrated handlebars. The result is a clean look and cleaner cable routing in the stem–headset area.

3D printing enables very precise fitment, so the spacer sits exactly where it should and doesn’t look like an add-on. The composite material with a solid internal structure withstands everyday loads from riding and handling.

Its low weight keeps your build light, which you’ll appreciate on long climbs and fast accelerations. At the same time, you get a part that doesn’t visually distract and supports an aerodynamically clean cockpit.

Technical specifications

The spacer height is 3 mm for fine fit adjustment.

The spacer weight is approximately 12 g for minimal cockpit load.

Compatibility is for a tapered steerer tube of type Tapered (1 1/8" - 1,5").

The package contents include 1 tapered spacer.

Conclusion

This FSA tapered spacer is a small part with a big impact on the clean integration of the ACR system. It helps you fine-tune cockpit height and the interface so the whole setup looks compact.

You’ll appreciate it especially on modern road frames with internal routing, where precise shaping and reliable seating matter. The Matt Black finish also blends easily with most components.
