the stem i have now has a negative rise.. someone wants to sell me one of these stems for 20$ so ill prob do it and then be able to decide if i need something different later on. I am kinda a noob so i dont really have a strong opinion at this point because i never really though about it on my current bike becasuse i just used the stem that came on the frame (its a conversion). For this build i will be selecting most of the componets so i am just trying to sort it all out
