The "S" stem was also made by GB, and I wanted to warn you that yours has been previously damaged and "repaired". You can see what it originally looked like here: http://www.ebay.com/itm/261221151556



It originally came with slits in the side and a cone expander. At some point in the past it broke (probably at the ends of the slits) and to repair it somebody ground an angle into what was left and used a wedge type expander from another stem. I suppose the stem is still useable, however it will have to remain very low in the steerer, pretty much bottomed out. Just thought you should know, and if there are any "max. ht." marks they will no longer be accurate.
