Should I choose Pinarello F5 53 or 54.5?

The sourced 54.5 adds 15.3 mm stack and 2.7 mm reach over 53. Compare both with your current frame and achievable bar position; height alone does not decide the choice.

What do CC and CE mean on the F5 chart?

CC means seat tube center-to-center and CE means center-to-end. The 53 label corresponds to 530 mm CC, while that row's CE seat tube is 500 mm. Neither number is the effective top tube length.

Does this F5 chart fit every F5 model year?

No. It was captured from the linked new F5 105 Di2 product, which does not specify a model year in the chart. Confirm that the seller's bike matches this generation before using the rows.

Pinarello F5 105 Di2 Size Chart & Geometry

Jump to the frame geometry table

The new Pinarello F5 105 Di2 has nine geometry rows, with fractional labels such as 51.5 and 54.5. The official table distinguishes seat tube center-to-center (CC) from center-to-end (CE). That distinction matters: an F5 53 has a 500 mm CE seat tube and a 545 mm top tube, so neither measurement can be guessed from the frame label.

Which bike does this chart cover?

The linked new F5 105 Di2 product chart, captured October 25, 2026. The source does not assign a model year. Do not apply these rows to an older F5, Dogma, endurance X or Grevil. Rider height and inseam bands were not published in the checked table.

Captured from the new F5 105 Di2 product, not an older F5 or Dogma. Size labels express the official CC column in centimeters (430 mm = 43 cm). Seat-tube lengths below use CE, the manufacturer's center-to-end measurement. No official rider height or inseam bands were present in this chart.

Keep CC and CE separate

Size labels here express the official CC column in centimeters: 530 mm becomes 53. The manufacturer's CE value is center-to-end seat tube length, which is 500 mm for that row. A seller quoting a seat tube measurement may therefore be using a different number from the nominal size.

Compare 53 and 54.5 by position

The 53-to-54.5 step adds much more stack than reach. If reach already suits you, check whether the taller frame still allows the bar height you want. Stem length, bar reach and spacers also change the final position; these two frame dimensions cannot settle the decision alone.

Do not turn a nine-size range into nine height bands

The official product table describes frames, not rider-height limits. Use a measured inseam, standover and a known comfortable position with Pinarello or a fitter. More closely spaced frame sizes do not make a height-only prescription reliable.
