well first if you dont have clipless pedals, get them. nothing will effect your speed more than the ability to use more, stronger muscles. from just quads to quads, hamstrings and glutes. i guarantee if youv never used them before, once you try them youll be giggling like a school girl about how fun it is to be going THAT fast.
if you already do have clipless pedals then...idk...aero bars maybe? im not one for spending 2 thousand dollars on carbon components to put on a 1 thousand dollar bike. if all else fails, make your lower body stronger, i hear that has something to do with speed
