ah, sounds like you want a nitto technomic:
http://harriscyclery.net/itemdetails.cfm?ID=418

but technomics are ~72 degrees, though they have super-long quills

you can get dynamics in 90 degrees. They have a longer quill than most regular stems, but not as long as a technomic

But if the quilll is long enough, the degrees doesn't matter.

A Nitto Technomic (http://aebike.com/page.cfm?PageID=30...ils&sku=SM1190) gives you about 6" of pleasure.

Theres also the Nitto Dirt Drop (http://cgi.ebay.com/NITTO-Dirt-Drop-...QQcmdZViewItem)

Profile H20, longer quill than anything I've seen barring the Technomic, and comes in 90 degree in a variety of lengths. 2-bolt modern faceplate, which is nice as well. I've used one in the past, seemed solid enough (eventually converted that bike to a threadless setup). Ugly though...

ended up going with the Nitto... am I going to have to remove my bar tape to get my bars in that sucker?

yes.

damit:mad: :rolleyes:

only one side, jwind, and if you run a brake may i suggest you unwrap the other side from the lever ;)

I was just thinking about that.... Though if I'm tearing of tape I might as well rewrap:rolleyes:

true

you can get a zoom stem at nashbar. I don't know that the quill will be long enough for what you want, but they are 90 degree and up to 130mm

Profile Designs H2O quill stems are available in various angles, including 90 degree and various stem lengths. The quills are relatively long.

Alternatively, if you like retro, Rivendell has some long quill stems like this:

i find it amusing when people reply without reading the thread.

funny. great bike shop humor.

Aa

Can you guys find a 180 degree stem for me?

Wait........

Generally stem reach is measured from the centre of one clamp to the centre of the other. Manufacturers do deviate slightly from this standard in a bunch of unpredictable ways, so that for example I hear a 10cm Nitto stem will be closer to another manufacturer's 11cm stem.

Stem angle is a complete cluster****, as we saw in this thread where no one knows what a 90 degree stem is. Basically some quote stem angle as coming off a horizontal line that intersects with the top of a bike, assuming a ~72 degree head tube. But the angle of the imaginary head tube varies and hence so does this figure. The angle of actual head tubes also varies and hence so will end results---a Nitto Technomic has a bit of drop when installed in my bike's 75 degree headtube.
But is a stem that sits perfectly along this hypothetical flat line a 90 degree stem? Or a 0 degree stem? This adds another order of cluster**** to this problem.

Others quote stem angle as the angle of the steerer tube to the stem extension when the stem is installed. This standard makes a lot more sense as there is no imaginary bike involved and end results are not relativized. This is the standard the OP was using when asking for a 90 degree stem, and the standard that baxtefer was using when he said Technomics are 72 degrees.

Tradition! No it doesn't matter but some people like the way a flat stem looks. Of course if you want to jack your bars high, your steerer tube or the quill of your stem may only get you up so far, and after that you need a stem with positive rise. Ditto for if you want to get your bars low, at some point you run into the top of your headset and need something with neg rise.

Profile makes a 90 deg. stem, but it ain't pretty.
