hello,

I recently got a pro bike fit. Everything went well, but now as my riding skill and comfort has increased, I want a more aggressive/aero position. I want to drop 1 spacer thus lowering the stem (it has about 3 1/4'' spacers on there). Will lowering the bars 1 spacer throw off the entire fitting? Or will it simply change the aggressiveness of the riding position? Should I do this myself or take it in?
