From the mind of Ruben Alcantara, the Rotar headset is something quite unique. Aside from the precision bearings and the high rise integrated compression ring / spacer design for simplicity of set-up, and 6061 – T6 CNC machining throughout, the breakthrough and standout feature on this headset is the bottom race spacer that sits between the bottom bearing and the crown race on the fork, that not only cleans this area up a bunch, it also raises the front end, eliminating the need for as many stem spacers, but also lays your head-tube back just a little. Can be used without lower spacer.
