That's the statement I'm not following. If the extension is 6.5 cm on the Dirt Drop stem, and the extension is 6 cm on the Technomic, the former will be .5 cm closer with the bars at the same height. The extension is the measurement from the bolt center, which is the same as the center of the headtube. Whether you get there with an up-angle stem such as the DD or the "7" style of the Technomic doesn't matter. To your original point, that would still suggest that you would be better off using the Dirt Drop stem, if your intention was to get the bars as close as possible without regard to height - Jim -- Jim Edgar cyclofi...@earthlink.net Cyclofiend Bicycle Photo Galleries - http://www.cyclofiend.com Current Classics - Cross Bikes Singlespeed - Working Bikes "You must be the change you want to see in the world."
