What's Included
  • 1x 3D printed top bearing cover.

The Roval Alpinist II handlebars are pictured for reference only and not included.

Overview

This MagCAD top bearing cover allows you to mount the Roval Alpinist II cockpit integrated cockpit to your 1st generation Specialized Aethos (2020-2025) road bike and minimise the headset stack height for a "slammed" setup.

This remodelled headset top bearing cover links the integrated design of the Roval Alpinist II cockpit cockpit to the more rounded shape of the 1st generation Specialized Aethos (2020-2025), improving aesthetics and allowing the use of an integrated computer mount out front for a super clean setup.

The 1st generation Aethos (2020-2025) has external cables, as standard. Therefore this top bearing cover does not have any provision for internal cable routing. This top bearing cover is not compatible with the 2nd generation Specialized Aethos (2026-).

To mount the Roval Rapide or Terra cockpit, please see our MagCAD Roval Rapide / Terra Specialized Aethos Top Bearing Cover - Slammed.

Application

All MagCAD headset parts are 3D printed in a durable Nylon to ensure they are robust to many years of use. As with any steering related components they should be installed by a competent mechanic and inspected regularly. Incorrect assembly or mis-use may result in damage to the headset components and/or injury.

This MagCAD Top Bearing Cover has a height of 5.1mm. With the Roval Alpinist II cockpit having a clamp height of 40.3mm this makes for a total stack height of 45.4mm. Allowing for the 3mm steerer tube cut specified by Specialized you will therefore require a minimum 42.4mm of fork steerer, measured from the top bearing split compression ring to the top of the steerer.
