2 degree of rise in stem, any difference...

[amator]

to effective horizontal reach and rise in height of stem...
assuming same length stem and HTA constant.

Lets say changing out from a 130mm deda zero-100 which is 82 to a 130mm deda newton 84degrees... am I going higher or lower.

The Newton stem will be 2 degrees higher than the Zero100.

90 degree stem = perpendicular to head tube angle.
84 degree stem = 6 degrees lower than head tube angle.
82 degree stem = 8 degrees lower than head tube angle.
73 degree stem = 17 degrees lower than head tube angle (parallel to a level top tube on a 73 degree head tube angle).

Depends wich way you mount it ofc. ´

The 82 degree stem will be either -8 degree or + 8 degrees and the 84 stem will be either -6 or + 6 degrees.

Id say you would find it hard to notice the difference.

You can use this chart to work out the exact difference in height / lenght.

I'm not inclined to flip it for the aroused look.
Basically trying to bring down spacers from 30mm to 20mm.
Was considering a 86 degree stem (newton) though I like my silver zero-100
aesthics much better than the newton.
BTW, the link is dead.

Your bars will be 4.5mm higher with the 84 degree stem in 130mm. So you could remove 1 5mm spacer and keep the bars in the same place.

thanks for performing CPR ! :beer:

Correspondingly, would that stem be "shorter" along the horizontal plain?

90 degree stem = perpendicular to head tube angle.
84 degree stem = 6 degrees lower than head tube angle.
82 degree stem = 8 degrees lower than head tube angle.
73 degree stem = 17 degrees lower than head tube angle (parallel to a level top tube on a 73 degree head tube angle).
IF, the stems are the same stack height...i.e. both are 40mm. iirc, the Newton is shorter than the Deda Zero.

Great tool for these kind of stem comparisons:

http://alex.phred.org/stemchart/Default.aspx

After plugging in your values and hitting submit, the upper left of the diagram will have reach and rise difference between the stems in mm.

Both the Newton and the Zero have 40mm stack height.

What a great tool. Where have you been for the last 10 stem purchases! :banana:

[93legendti]

I did not know that.

[cadence90]

I did not know that.
I didn't either; I just checked the website.
But your point is correct, and a good reminder.

I learned the hard way trying to figure out why switching from an FSA os-115, 110mm to an Oval Concepts 110mm stem made the reach feel different.

[amator]

Using Lurpy's great link, I keyed in 130mm and then 10mm spacers for both and then for ANGLE: I keyed in 6 and 8 respectively.

The results showed that the 8 degree (82) would be 4mm higher than the 6 (84), contrary to what Sivat and cadence90 advised - that the 84 degree stem would be higher than the 82.......?

*Ok, My mistake, I think I'm supposed to key in 82 and 84 and not 8 and 6, because when i did that, the 84 angle stem was higher.
Sorry for the confusion.

Go here and you can figure and play with various stem configurations. Very informative..

Yes, but the difference is within a mm.
