I want to make sure my thinking is sound...

My current bars, Cowbell 2 by salsa, have a 76mm reach... It does feel a bit far for my fingers to wrap around the DCLs when I'm in the drops.

So, I'm thinking of going with a Zipp Service Course C, a bar with 70mm reach. I think that'll address my hand wraparound comfort on the DLCs.

Now, I'm effectively shortening my reach by 6mm changing out the bars..I feel I can extend there a bit already, so in order to compensate going up 10mm (From 90mm to 100mm) with the stem is the way to go?

That'll net me +2~mm (with a 17 degree stem?) while getting my hands more comfort in terms of reach I'm thinking.

I'm trying to figure out rise as well...my bars will be up a little higher if I go with a -17 100mm stem? I was told that -17 = a 0 degree stem, meaning perpendicular to the head tube...I'm not quite sure how to translate this yet...I came across this drawing and I almost got it...I'm hazy on what -6 versus -17 stem angles will do:




Ok...I used an online calculator and I came up with this...

My current versus proposed config:

Stem Angle: 20.0° 37.0°
Difference: 17.0°
Stem Height: 59.0 mm 69.6 mm
Difference: +10.6 mm
Stem Reach: 74.3 mm 76.4 mm
Difference:+2.1 mm
Spacers: 30mm 10mm



This is if I go with a 17 degree 100mm stem and remove 20mm of spacers
