Here's the dimensions from Probikekit for the Dolan 50cm:
Seat Tube: 50cm
Top tube: 525mm
Seat Tube angle: 75
Head tube angle: 72
Iro Angus (supposedly their "old school track" frame) 50cm:
Size: 50cm
Seat tube (c-c): 46cm
Top tube: 52cm
Head tube angle: 72
Seat tube angle: 75
Is it because of the size that I'm looking at?
