Why don't more builders make the zero rise stem, I love the old Salsa SUL steel stems.

that's a - 17 degree stem.

You just talking parallel with a non-sloping top tube? Giving angles is always subject to interpretation.

A zero degree rise stem is a stem that forms a 90 degree angle (right angle). Take the stem out and hold it. It forms a 90 degree angle. It has nothing to do with the tt of the bike. If you flipped a zero degree stem it would still be a zero degree stem and would look identical flipped or not flipped. Stem degrees are based upon deviation from 90 degrees. So a 90 degree stem and a zero degree rise stem are the same.
A 6 degree positve rise stem could be called a 96 degree stem, because the stem would measure 90 degrees + 6 degrees = 96 degrees. But if you flipped a 6 degree stem, you would have an 84 degree negative rise stem: 90 degrees - 6 degrees = 84 degrees.
I am absolutely correct above or a total idiot. Hopefully the former. It is my understanding, anyway.

You are absolutely correct. It's just a matter of perspective. Ones view point can be different but still the object is the same. To understand the secret one must know from where to view.

Sandy the former math teacher is 100 % correct. LUV the 0 * rise stem
Why don't more builders make the zero rise stem, I love the old Salsa SUL steel stems.Because it is inherently less flexible, or less adjustable? Flip it and you get more of the same.
At least with a few degrees (4 to 6 seem more common) the variation in angles can be worked with a few spacers to cover a much larger range.
I can't think of any other reason.

Because zero degrees from perpendicular to the steerer IS a rising stem, or because a successful midwestern parts distributorship defined where zero is at(mo?) Zero rise, or zero degree works for me... zero degree rise is a bit too much excessive but confusingly conflictive extra no clarifying redundanciness.
Parallel to the top tube is a safe aesthetic bet without a drawing...

This is an easy one: Aesthetics.
For me, the closer the stem is to being parallel to the TT the better looking the bike. Used to be, when all road bikes had horizontal top tubes, and since most head tubes are about 73* all you needed was a -17* quill stem. Now we have a) sloping top tubes, b) threadless steerer tubes, so lots more combinations are possible. However, the bottom line is still parallel to the TT is better, and since there are very few 17* sloped top tubes, only the bravest, fashion-flouting, geekiest, white tape around the nose-piece glasses wearers, do this. :cool:

Like Louis, I have a tendency to like stems that are close to parallel to the TT.
If it's a sloping frame, an 84 or 82 looks good. On my level TT frames, I like an 80. I'd rather see a few more spaces and a 84 degree stem than a 90 degree without any spacers, but that's just my eye. For some, it's necessary to have a 90 degree or more.

96 degrees? How obtuse! :p

A cute observation. However, to what degree must this plane conversation continue? Let's ask Ray, I'm sure he has a point he'll share with his circle of friends...

Easton makes their nicest stem in a zero dgree 31.8

I've become a big fan of the 90 degree (or zero rise) stems. A flip-flopped 84 degree stem just looks too dorky for me. My fav is not made anymore, from what I can tell: Salsa Scandium Pro in 26.0 bar size. The regular Salsa moto is pretty good, though.

96'rs aren't all bad, especially when you're working with a bike that fits pretty well on the top, but has a head tube about 3cm too short. :o

I use the Thomson mountain bike stem on my road bike to get a solid 0 degrees rise. I think it looks fine and it is a great stem.
