  • From BikePro review of the 1-1/8" X15 version (which is the same besides the dimensions as far as I know):  STRONGLIGHT X15 1 1/8" MTB HEADSET

    The X15 takes the mechanical design of the previous Stronglight headsets and beefs it up for a 1 1/8" size model. Like the other Stronglight headsets this uses needle bearings that revolve against steel races placed on or in the aluminum parts. The headlock nut is forged, then machined. The sizable piece of aluminum looks rather like the Mavic top piece. The headlock steerer threads are well cut and there is a O-ring stem seal recessed within a groove inside near the top. The X15 has a rather clever headlocking system. There are two holes drilled 13.5 mm from the bottom of the piece, one on each side. The holes are 1/4" in diameter and are spaced so the drilled hole passes through the edge of the fork steerer threads inside the headlock. Stronglight slides a modestly tight fitting White rubber tube into the hole, and slides a small steel bolt with a 2mm hex head through the tube. The bolt is cinched into threads tapped into the aluminum on the far side of the headlock nut. As the bolt is tightened within the rubber tube it compresses the ends of the tube forcing it to expand and make more firm contact against the fork steerer within the headlock. This bolt and compression tube assembly is covered by a removable Black rubber shield when the headset is in use, (like the Mavic). The bottom of the headlock piece becomes the point of contact for the cone race, which is Black steel and lays against the aluminum. A forged aluminum upper "cone", that is really an upper cup race fits into the top of the head tube. Another Black steel race lays into it. This alloy cup race holder has an O-ring seal recessed into a groove around its lower skirt. The lower bearing assembly is more traditional. A forged then machined aluminum alloy cup is pressed into the lower head tube, with a Black steel race laying inside it. The fork crown race is machined from aluminum with a recessed O-ring seal located in a groove around the skirt. A final Black steel race lays over this lower cone race. The X15 uses twenty 2.5mm diameter needle bearings, each bearing being 4mm long held in a White plastic retainer. The 2mm tightening wrench is not included. The X15 is made only in a 1 1/8" diameter, and only with a Pewter Grey (now being called Ti Grey, but it isn't really) anodized finish. It weighs 155.5 grams and an approximate stack height of 40.3mm. $ Price in Catalog
