Chorus™ Threadless™ Headsets The Chorus groupset proposes three types of headsets: traditional threaded headset, Threadless headset and Hiddenset headset.

The traditional threaded headset surely needs no further presentation – its smoothness, longevity and reliability characteristics have set the standard for years.

The Threadless headset is intended for unthreaded fork steerers. It is extremely light and allows quicker and more precise adjustment than its threaded counterpart, besides being lighter and longer lasting.

The Hiddenset headset is integrated into the head tube of the frame, providing an extremely elegant look thanks to the aesthetical balance achieved between the fork steerer and the frame and between the frame and the handlebar stem. The Chorus headset is light, smooth, long lasting and easy to install, and is available in the standard version or with a TTC cap.
