hi...i've searched.....found an old ross signature at dump today....it has semi-horizontal drop outs....i am gonna convert for a buddy....it needs a new bottom bracket......would the size most likely be a 68mm?....from mid 80's....thanks, bob

Signature is a line. You have a model number?

Some of these frames are nice. I had a triple butted Ishiwata touring frame that rode like a dream.

it is the Ishiwata tripple butted....i wish it were my size....
