FAQs
What does ACR stand for?
ACR stands for Aero Compression Routing, a system designed for internal cable routing through the handlebars, stem, and fork steerer tube for improved aerodynamics.
Is this compression ring compatible with all headsets?
No, this compression ring is specifically designed for Deda Elementi ACR headsets and requires headset bearings with a 36° x 45° angular contact. It is not a universal part.
What is the function of a compression ring?
A compression ring, in conjunction with the stem and top cap, applies outward pressure to the headset bearings, securing them within the head tube and eliminating play for smooth steering.
What is PA66 Nylon?
PA66 Nylon (Polyamide 66) is a strong, durable, and heat-resistant thermoplastic commonly used in engineering applications. It offers good mechanical properties and wear resistance.
Can I use this with standard (non-ACR) handlebars/stems?
No, this compression ring is intended for use with ACR systems which route cables internally. It will not function correctly or provide the necessary compression with standard external cable routing setups.
How do I know if my headset bearings are 36° x 45°?
The bearing angle specification is typically provided by the headset manufacturer. You may find this information in your bike's original specifications, on the bearing's packaging, or by measuring the bearing's chamfer angle.
Troubleshooting
Headset feels loose or has play after installation.
Re-check the headset preload and torque specifications according to your frame and fork manufacturer's guidelines. Ensure the compression ring is seated correctly and the top cap bolt is torqued properly.
Steering feels stiff or notchy.
Inspect the headset bearings for contamination or damage. Ensure the compression ring and other headset components are clean and free of debris. If bearings are compromised, they may need replacement.
Difficulty installing the compression ring.
Ensure the steerer tube is clean and free of burrs. The ring should slide on smoothly. If resistance is met, double-check compatibility and ensure no internal cable routing components are obstructing its path.

Setup, Compatibility & Care
Setup:
- Ensure your bicycle headset is an Aero Compression Routing (ACR) system.
- Verify that your headset bearings are compatible with the 36-degree x 45-degree interface.
- Install the compression ring onto the fork's steerer tube, ensuring it sits flush against the lower bearing.
- Proceed with the headset assembly, torquing bolts to the manufacturer's specifications to achieve proper compression.
Compatibility:
- Primary: Deda Elementi ACR (Aero Compression Routing) headsets.
- Bearing Angle: Requires headset bearings with a 36° x 45° angular contact.
- Material: Compatible with standard aluminum and carbon fiber steerer tubes.
Care:
- Clean with a soft, damp cloth. Avoid abrasive cleaners.
- Periodically check headset tightness and inspect the ring for signs of wear or damage. Replace if any damage is found to prevent headset issues.
