Is it the chainstay themselves that are the same length, or the horizontal distance between BB and dropout? If the latter, then a different BB drop could affect the length I guess. Wouldn't have thought it would be anywhere enough to stop a previously correct chain fitting though.

Both vertical drop outs?
