Threaded Stem Rise Question(5 posts)

Threaded Stem Rise Questiontrout_bum

I want to get either a Salsa S.U.L or Classic Road threadless stem-on their website I see 75, 90, 105 degree rise options. In catalogs I see 0 degree rise offered. Does 75 deg =0 rise stem? I think I want a slight rise on stem so does this mean I want a 90 deg. stem? Sorry if answer to this is obvious.
The "standard" HTA is 73 degrees, so a "0 degree" stem isbill

a negative 17 degree stem -- 73 plus 17 is horizontal. Same thing. A 90 stem is actually plus 17, the most rise I think you can get, although there are stems between these, and my trigonometry is too weak to tell you whether if you turn any of these over you would get more rise than a 90 degree.

According to several catalogs I've read, the the 'angle' refers to the angle of the stem in relationship to the steer tube. Therefore a 90 degree stem is perpendicular (90*) to the steerer. A 75* stem is almost horizontal to the ground. A 105* stem has quite a bit of rise. If you want a slight rise, the 90* stem would be the ticket.

I am confused. I am looking to buy the Profile h20 stem. It says 0 degree. Is it horizontal, is there a rise or a dip (opposite direction)?
a Profile 0 degree stem is the same as.............gogene

a 90 degree stem. Profile takes their mesurments as degrees from perpendicular. So a 0* stem is perpendicular (or 90*) to the steertube. There would be a slight rise when the stem is installed.
