I actually went through 3 iterations of bar position before settling on this. The initial build had an 8mm spacer above the 3mm red "bling" spacer with a -17 degree 120mm stem. That gave me a 101mm saddle to handlebar drop. Proved to be a little too aggressive for me, so I took out the 8mm spacer, cut off the extra 8mm of steertube and replaced the 120mm -17 stem with a 120mm, -6 degree stem. That raised the bar enough but still felt like the position was wanting to push me back a bit. So, in the end I tried a 130mm, -6 degree rise (shown in pic above, kinda dark, sorry) which resulted in a saddle to handlebar drop of the current 88mm, which I'm really finding quite perfect. In the process I also increased the saddle setback by 4mm. Plenty aggressive, looks good, and handles great. The fine tuning has been the result of trial and error and lots of miles till you "get it right". You'll know when that is. Kind of have to be willing to try minor changes to get that perfect fit. And even then, the body is highly adaptable, to a point. I'll never sacrifice a good position to get a certain "look". But in this case, I think I've achieved both.
I generally like to keep the saddle to handlebar drop between 7 and 9cm.
