This is a vintage McMahon titanium frame. It’s a size 17”. This shows normal signs of wear with some scuffing etc. One small ding on the down tube which doesn’t affect performance. There’s a small piece of material rolling around in the top tube (as per my observation). It doesn’t affect performance.

Here are the frame measurements which are taken by me and there might be a small margin of error due to this.

Seat Tube - 18” c-t

Top Tube - 23” measured along the top tube

Head Tube - 10cm
