HI,
I started with a MTB to, with rather large tires, I noticed a big difference in wind resistance and ability to mantain speed. Many MTB are built for off road and have considerable rolling resistance and in my case I had a shock that was sapping away my pedal power by damping the pedal stroke.Plus many MTB have a more upright ridding positon this creates alot more drag. when I go to the drops onmy road bike I usally speed up considerably without any additonal effort. Hey I ve only been riding slightly over a year. so there's alot more experts on this issue.
My first road bike was a used 86 steel and I really could ride it faster than the MTB .
