Hi, i've a problem with reaching the handlebar. Even though in aero position i can't see the front hub through the handlebar (as it should be) but i always have to sit in front of the saddle to feel more comfortable and to be able to apply more power. My saddle post has a setback and stem is 140mm. I don't know which would be a better idea. Changing the saddle post with a zero set back one or shortening the stem to 120mm or so. What would you recommend?
