Thanks, Gabe, but after searching all three lists, I found several references to the belt, but no specs. (I did manage to find the specs for a Motobecane, but that doesn't help me.) If someone else remembers the post, I would appreciate the info.
Gabe, if it's not too much trouble, could you perhaps check the belt you bought for the numbers, or maybe you j=have them on a receipt? $7 sounds a whole lot better then $20 plus shipping!
