A-X, that makes sense. I was trying to make it out as EX, wasn't aware of the AX group. Bike is from the late 80's I'm told.
Lug is not cracked; that's just some dirt. Sorry about the lousy pic there; camera batteries died.
Headset is OK; thanks, should have mentioned that.
And no, I don't have a good wheelset to try. I've been out of biking for about 20 years, and then it was mountain bikes. I do have some lumps of rust left that an optimist might identify as MTB's, but none of them are ready to go either.
LBS? Might be worth a shot; I didn't realize the work wouldn't cost too much. Just have some "BS" though; no "L" involved (I'm kind of out in the country).
Thanks all,
Rob
