angle of rise is the angle of the stem when mounted to the steerer.
length is the distance ebtween the center of the two clamps.

3 means bar height... like super high for dirt street (ns bars for example)
4 goes for bar lenght, like super long bars for DH, that almost look like plane wings lol

There is three four measurements for a stem:

1: Steerer tube width - 1and1/8th or 1.5"
2:Handlebar diameter: 25.4 mm or 31.8 mm
3: Angle of rise
4: Extension in mm (between steerer tube and bar)


Spank make good purple stems I think.

haha you lost me in questions 3 and 4.
sterrer tube is 1 1\8
handle bar is 31.8

Well for 4 that is the extension so like xc stems are generally really long and DH really short and it can be anywhere inbetween

I dont really know what three is but i suppose some stems are flat along and some make the bar higher up

Dude straitline is soo worth it though, super light, all CDN made, even the metal is from canada. The company doesnt have some huge factory either, just a metal shop on the island....and dude so freaking strong.
