Picked up a set from Jenson for $210 (sweet). Problem is, the rear wheel is out of balance (like a car wheel can get). If I grab the cassette and spin it fast it's got a hop in it. I checked the rim and it is true and round. I think it's got a heavy spot in it where it's pinned together. I taped a small bolt to the opposite side (where the stem goes) and it's perfectly smooth then. Don't know if it would be noticeable once it has a tube and tire on it. Is this typical for these rims or did I get a dud?
