No stem with a 25.4mm or 26.0mm clamp diameter has a longer quill than the standard Nitto Technomic, but the Nitto Dirtdrop stem will give you the overall height you need because the forward extension is angled upward. Rivendell has them in 26.0mm clamp diameter, and if you need it with 25.4mm clamp diameter they have a shim available. You might also look at the Nitto Periscopa stem if you need a 25.4mm clamp diameter. The Periscopa is a less expensive version of the Dirtdrop and comes in 25.4mm clamp diameter-
Not the question you asked but it seems that if you need 180 mm of stem rise, you have the wrong bike and/or the wrong size frame.
oh I'm coming to that conclusion!! but at 5'7" with a 29" inseam, a 52 cm seemed on the mark for me and that's what I have. Problem is, I like to be fairly well upright most of the time and my arms aren't very long so I'm going to be a tougher fit in general.
