Hello. I have typed my body dimensions in the competitive cyclist's fitting calculator and it gave me back the recommended geometry of a road bike:

I am interested in buying a new Giant TCR Composite or Advanced but I can't understand which is the best size for me.

Geometry:



Height: 5' 8.5 (174cm)
Inseam: 2' 7.1 (79cm)

Could you please help me?

Thank you.
