Ok guys, how about this one... I think it is a Predator- but once again am no Schwinn expert. This has a round head badge, and both top and bottom tubes are completely oval- not part oval like the Sting. The SN#R88378 is on the drive side and on the left side rear dropout it is stamped A-PRO. Any information on this frame/fork is much appreciated as usual.

Is it a Schwinn Aerodynamic???

All these experts here and nobody knows what this frame is??

Can't say I've ever seen one quite like that. At first I thought, Predator Chromo, but they had a gusset and I don't think both tubes were oval like that.

It has a Schwinn headtube badge though, otherwise I'd think it was one of those Akisu-made frames that got marketed as many different things. Many of those had Aero tubing like that as well.

i had one just like that it was a 84 predator. the decals are the ones that had the monster on them.
good luck finding those though.

Predator eh? Thanks once again Reverand!!

Any #'s on the headbadge?

Hmmm...I think he's right. I saw one or two of those BITD...with that bat-wing monster thingie on the decals, black and blue i believe.

As for the decals, may be hard to find but ya never know...keep combing the bay, to start!

it should have decals like this.

Reverand as always you are correct once again. Thank you for your vast knowledge!
