I don't know a lot about bikes but this is what is on the bike. SR apline sport, Champion #5 , Chrome Molyboen steel seamless PG tubes. Made in Japan. Hand brake says Dia Compe, back gear says Suntour ARX, shifter says Suntour power shift. I'm not sure how to measure a bike but from the pedal in the lowest position to the top of the seat tube is 27". This is a bike for a female. Overall good shape, some minor dings, and some discoloration on silver metal (aluminium?) parts. Here's a basic pic. I have a matching guys bike that I think is 26".
