Does it still have the decals on the downtube? If it's a Wicked it should say "Wicked Fat Chance", otherwise it will just say "Fat Chance". You have a 1987 frame. I believe the 1987 Wickeds used the chainstay-mounted U-brake, and the 1987 Wicked serial numbers did not include a W to denote Wicked - that began in 1988. So it's a bit tricky to determine which frame you have if it doesn't have the original decals. There are probably *some* differences between the early Wicked and regular Fat Chance frames, but I don't have enough experience with the regular Fat Chance frames to know what to look for.I got a hold of a what I think is a 87 Fat. S/N 87406 it has a u brake mount. My question is what
the difference between a regular fat chance and a wicked? Its still has the original paint, its bright blue with a yellow fork.
