Main features
Technical description
Integrated headsets sometimes require the use of micro spacers to adjust the machining depth in the steerer tube, thus ensuring a perfect fit between the various components.
FSA MW259 micro spacers must be placed between the cap and the compression ring to prevent the top crown race from interfering with the upper part of the steerer tube.
Available in different variants for specific diameters:
