I'm upstate a short drive from a bike shop advertising a CAAD10 Black with Di2 for under 2k. Very tempting, but it's a 54 and I ride a 56 generally and the geometry of my guru is the following...

Virtual Size: 569mm
Measured Size: 520mm
Top tube c-c: 570mm
Head Tube: 160mm
Seat Angle: 73°
Head Angle: 72.5°

Yeah, I know, anyone want me to pick it up for them?
