Can't remember for sure whether the shop I worked in at the time ever brought in any of those 26 X 1 3/8" Cannondales, but I do remember them being available for at least one production run. We definitely stocked Cannondale SM500 mountain bikes with a 16" frame size and 24 X 1.75 wheels front and rear (and I still ride an 18" version with 26 X 1.75" front and 24 X 1.75" rear wheels).
