I have one and I love it. It's solid, yes heavy but robust. My 285lb carcass can ride gravel roads without getting pinch flats and the SIS shifters shift smoothly. I bought it to flip it, but then rode it at lunch and liked it too much to sell it. It's now my go to bike when I go out riding with my son because it can go anywhere we want to ride.
