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.

Give CC a telephone call and have your numbers handy. They know what they are talking about and will help you select the proper size. Or ... visit your LBS and have them fit you.

So you're telling him to call Competitive Cyclist up after he used their free size/fit tool on the web and have them interpret the data so he can buy a bike someplace else?

Do you know what the word "or" means?

I will have to wait until a TCR '12 become widely available. So, initially, I am looking for an opinion...

Thank you.
