Not So Low Stack Internal Cable Routing Adapter for Time, De Rosa, etc. w/ standard FSA ACR headsets|

Why do you want it?

You seeking a a sleek 15mm headset cover that helps you use your FSA ACR headset with an ENVE InRoute bar or stem for your Time (2025+ ADHX / ADHX 45 / Alpe D'Huez, Scylon), De Rosa (Merak, Idol, 838, Spider), or other bikes that are using a standard FSA ACR headset.

These adapters may also fit other bikes that use standard-dimensioned FSA ACR / SMR internal routing headsets with a ~56 mm OD headtube. They work best with electronic drivetrains.

What is it?

This set of parts is modified from my general headset collection to have a 55.8mm OD to match the 56mm OD headtubes used by these bikes. 

You can verify this fitment by measuring your bike with the bearing removed along the inside of the head tube. It should measure around 8.7mm from the top edge of the frame to the bearing seat. Alternatively, you can message us to confirm fitment.

There are currently ONE versions of this Part.

1. The Enve version is designed only for use with the Enve InRoute system. This design replicates the a 15mm headeset cover and spacer combo and is compatible with Enve split spacers.
   

Other versions like an EXS or Tavelo Avro compatible barstem may also be available. Please contact us if you want a different version

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. Custom orders may take up to 4 weeks, depending on the sourcing of parts needed to complete the design. Bulk discounts are available. Please message / email for more information.
