I have a Giant Avail and love it! My tires say 700x250...they are really skinny. I have not been fitted for the bike by bike shop. I fitted it myself using computer specs.

I am used to riding my specialized hybrid which rides more like a road bike (except for handles). I just can't seem to feel confident on this bike?? I'm way more nervous about hitting a pothole or going too fast and not having control.
