Ive been riding my bike for around 7 months, over 2,000 miles and have mproved my average from 17's mph to steady 19's mph. Im riding 50 to 80 miles per ride.

My bike is a specialized roubaix, and i have to say, very confortable, ive riden 375 miles in 3 days, pain free. So im sure my fit is nice.

On a few rides my group has started to d sprint moments to see who can hold and try to see max speed. Ive reached 26.7 alone sprinting, and now would like to start alterin position.

Ive noticed how relaxed my bike position is, because my handlebar is slightly lower than my seat, just a tiny bit. Yet i see* many around me that have this massive diffence in seat.vs handlebar hight difference. I guess this is the big difference between relaxed and agressive.

In an effort to get a better sprint, last night i lowered my handlebar 1 small spacer and one big spacer, looks* like half an inch lower. The spacers over the stem look silly to me. Is this making sence? Does 1/2 an inch make a real difference? My bike has a bent top tube, does this affect the position vs a straght tubed bike?

*need to be cautious looks can be wrong!
