Pinarello X vs Specialized Tarmac SL9: geometry and fit comparison
Matched sizes, stack and reach deltas, and a fit check against your own body instead of guessing from two separate size charts.
The Pinarello X is built as a endurance geometry frame, the Specialized Tarmac SL9 as a race geometry frame. The Specialized Tarmac SL9 cockpit runs about 25 mm longer, a noticeably more stretched position. Across matched sizes the Pinarello X and Specialized Tarmac SL9 front ends are within a few millimetres of each other, so posture will depend more on cockpit setup than on the frame.
For the Pinarello X in 600 there is no Specialized Tarmac SL9 size with a comparable position: the range simply does not reach there.

FAQ
Which has the taller front end: Pinarello X or Specialized Tarmac SL9?
Across matched sizes the Pinarello X and Specialized Tarmac SL9 front ends are within a few millimetres of each other, so posture will depend more on cockpit setup than on the frame.
Can the same rider take different sizes on these two bikes?
Yes, and it happens often: frame labels are not standardized. Use the matched-size table for geometry, then run the fit check below with your own measurements for each bike.
