I heard the Conti Gatorskins were heavy, and to be honest, I have the largest size... 27"x 1 1/4". People must run on helium or something because they I can't tell a difference between them and my old 27" x 1 1/8" when holding them up by my pinky finger. I've only got about 8 miles on them, but they are freaking nice to roll on. Over the coming month, I get to test them on the construction zone riddled area of my commute.
