| Recognized as being
among the first to make needle bearing headsets, this is one of the
finest and lightest versions we have seen. It starts very similarly to
other needle bearing units. There are six aluminum pieces. Five of them
are cast and cleaned up by interior machine polishing. These are the
cone race elements, the bearing cup elements and the head lock nut. The
head key washer is stamped from sheet aluminum. There are four beveled
steel races, one for each of the cup and crown elements. The needle
bearing retainer has twenty bearings in it. Although this headset has
no rubber seals or skirt gaskets, with the tolerances that the parts
are machined to, it probably doesn't need it. With the parts just
resting on one another, and with no grease, the pieces move very
freely. Available in English thread in Blue, Silver or Black. The A9 does not appear in the 1982 Stronglight catalog, and does appear in the 1984, 1986, and 1987 Stronglight catalogs. These catalogs show the A9 locknut as marked 'Stronglight' only, and not as 'Stronglight France' or 'Stronglight Spidel.' |
