I converted too flat bar from a drop bar and my time going to work is about the same 8 miles in 32 mins .
But on a longer distance dropbars are definitely faster.
Yeah doing 8 miles in 32mins i am flat out i will not be able to do this speed over my sunday route which is around 35 miles on a dropbar bike where i can hit average 16.8mph .its much easier holding a faster speed on a dropbar.
