Can the same rider take different sizes on these two bikes?

Yes. Frame labels are not standardized, so the same rider may need different sizes. This comparison deliberately avoids a generic matched-size answer and hands your measurements to Bike Fit instead.

Which has the taller front end: Pinarello X5 / X7 / X9 or Specialized Tarmac SL9?

Across matched sizes, the Pinarello X5 / X7 / X9 stack sits about 8.3 mm taller than the Specialized Tarmac SL9, which generally means a more upright position before spacers.
