Hi Luca,

Height: 170 CM
Crotch height: 79 CM
Arms length: -
Racing or amateur position: --
The correct size of the Specialized Tarmac SL8 racing bike is 52, 54 is too large and can only be taken into consideration in the presence of a professional cyclist's riding position with high trunk flexibility and excellent training.
Since you are not a professional, I believe that the best choice is to purchase the size 52, to which possibly add an 11cm attachment instead of a 10cm one.
This may not even be necessary if you prefer a less forward-leaning torso position.
By eliminating the thicknesses under the stem and using a 10cm stem, it would already have a good fit in the saddle, if it then combines an 11cm stem it will have a typically racing set-up.
At a size 54, he may be forced to put a size 10 binding and some shims under the binding.
In theory neither size is perfect for her, but the 52 allows her to make fewer changes and have a more balanced and aesthetically pleasing frame.
Excellent choice and excellent racing bike.
