This Nitto Technomic Standard (not deluxe) is one notch down from the Technomic Deluxe on the totem pole of fanciness and costly fabrication methods . Rather than being cold-forged, it is gravity cast. In other words, it is poured into a mold, rather than being hammered into shape with a forging die (a giant and powerful press). The gravity refers to the way the molten aluminum is allowed to cool slowly, while gravity floats the bubbles up to the top (like when you pour soda), resulting in a dense, void-less final product. It's a strong way to go, and since it's made by Nitto, no worries about its safety. Go this way if you want the extra length (the tech deluxe quill is 190mm, standard is 225mm). Usually we sell these to folks who are retrofitting existing bikes that are too small. If you're starting out fresh, you shouldn't need this unless of course, you have severe back problems and can't really bend at the waist.

The 10cm stem is available in both 26.0 and 25.4mm clamp diameter, the 8cm in only 26.0mm, the 9cm only in 25.4mm.

If you need something even higher than get the Stem Riser.
