Remedial question : stem rise(2 posts)

Remedial question : stem riselitespeedchick

I am accustomed to seeing stem rise quoted as rise abouve 0 degrees. i.e. 10 degree, etc.

I need to get a shorter road bike stem, but I like the rise the current one has. It is listed in ads as 80/100 degrees. I assume that means that measured from 90degrees as being parallel to the ground, that means the stem has a ten degree rise or can be flipped around to a negative 10 degree rise (in MTB terms).

So...I looking at an ITM stem that just says 80 degrees. Will that be a 10degree rise, the same as my current one?

I'm sure this is a stupid question, sorry. Thanks in advance!

depends on HT angle. So, a 90 degree stem rests probably 16* on a 74* HT. A -16* stem will be parallel to the ground. Most manufacturers make a -10*, like the ITM.

So, an 80* stem flipped is +10 the other way, or 100*. As it is the same as your other one, you shouldn't have a problem. The height will drop a bit, but if not a drastic length change it should not be noticeable. A shorter stem is sometimes easier to deal with if a bit lower.
