yo stem math

[Fat Robert]

what's the difference in bar height for two 120mm stems: a -17 and a -6?

i'm thinking its about 15mm, but hey, what do i know, yo.

its a question of 55.5x57 or 55x57...when that scott sells, i think its time to start the FATMO-jet project....

If you Google "Stem Rise Chart" or something like that you will find a chart which shows the difference in rise and reach for various angles of stems.

-17 adds 19mm drop and 4mm reach over a -6 on my desk.

I have a spreadsheet that calcs the comparison, but I don't know how to post it as a file. If you want it, I can email it to you.
