Hello Squarenoise and thank you for your response. I just went upstairs to check, and the metallic brown 610 touring bike has the front fork brake ons which have never been used. Again, the beginning “M” of the serial number shows on this bike. I measured both the 610 and 710, and they are 23” or about 58.5cm.
