ok, so while the picture does appear to show a 6 speed, it is in fact a 7, I just went and counted a couple times to confirm. With that being said, can you really tell if it is a freewheel or cassette? I've read sheldons article and still can't tell what I got. There is no bulge in the body of the hub, but that doesn't confirm anything... Is there an easy way to detect, or are you guys sure it is a freewheel even with 7 gears?
