Low Stack Internal Cable Routing Headset Adapter for Quick Pro ER:One |

Why do you want it?

You are seeking to pair the hottest road bike in 2026, the Quick Pro ER:One, with bars or stems from FSA, Deda, or Enve.

Or you want the ability to use any of the adapters we have available for the FSA system that allow you to use stems from Specialized, Kalloy Uno, Zipp, or just round stems.

What is it?

This replacement headset cover takes the place of the Quick Pro item and allows you to use spacers, adapters, stems, or 1-peice bar stems from the bransd you select. 

This line is specifically designed for the Quick Pro ER:One only.

There are currently THREE versions of this part.

1. The FSA / Vision ACR version allows you to use FSA ACR split spacers or transition spacers for the FSA / Vision ACR system. This design has a height of 5mm.
   
2. The Enve version is designed only for use with the Enve InRoute system. This design features a height of 5mm and is compatible with Enve split spacers.
3. The Deda version is designed only for use with the Deda Alanera Spacers, Alanera Barstem and the V2 Superbox stem. This design features a height of 5mm and is designed to fit under the transition spacer supplied with the bar. Deda Alanera spacers can be used between the headset cover and transition spacer.

How is it Made?

These parts are printed in the USA on Commercial Grade HP Multi-Jet Fusion machines. Parts designed to hold preload are made using PA12GB. While this material costs over 2x more than traditional PA12 Nylon, the addition of the glass increases its strength under compression by 80% and, in this application, eliminates creep. Given that SLS and MJF printed nylons are only 60%-70% of the density of the high-pressure injection-molded parts made by OEMs, this assures OEM-level performance.

This part must be properly installed and the headset preloaded to the manufacturer's specifications.

Stems, bikes, Headset Split Ring, etc., not included unless otherwise specified.

The part is guaranteed to fit. If not, you will either be eligible for a refund or remakes until this part fits.

Note: Items are produced upon order and have a lead time of 4-10 days. Bulk discounts are available. Please message / email for more information.
