Prime's mission is to make your ride better, which is why the Doyenne Integrated Headset ensures smooth steering for many miles in all conditions, thanks to its superior reliability, quality and performance.
The Doyenne Headset features highly polished angular contact bearings to ensure smoothness, and the top cap is CNC machined from 6061 alloy and sealed to keep moisture away from the bearings.
To protect the lower bearings, Prime has included a CNC-machined 7075 alloy crown race.
