I am currently riding a Colnago C60 and I will soon order a Pinarello F10 (same geometry as the F8 a AFAIK) Disk.
My C60 is a 48S (Reach: 383; Stack: 528; Top tube: 530) with a 110mm stem/ -8°. No spacer.
A quite nice fit for me (170cm, 78.5cm inseam)
For my F10 to come, I am thinking about getting the F10 in 51.5 which is quite similar to my C60 (Reach: 380; Stack: 527; Top tube: 535).
And then with a 110mm stem/-10° (or a 100mm) depending on how low/high it is really without spacer.
So that's my thoughts based on the figures of the geometry of the F10.
But who has a "real life" comparison between the C60 and the F8/F10 in terms of the geometry?
Is there anything I should consider when ordering my F10 now in terms of the right size? (i.e. should I go for a smaller size 50 or a bigger 53)?
Im riding 50S C60 and also have Pinarello FP3 in 53cm size. When i was buying C60 i had a chance to test ride Pinarello Dogma F8 in 51.5 cm. And it was fine with 120 mm stem (C60 and Fp3 i ride with 110mm stem), and 25mm spacers under the stem (C60 have 12 mm, FP3 about similar).
I would say that 51.5 will be almost same match to ur 48S.
I will pick between 51.5 and 50 (or 47) based on this things:
- Do u feel that u'll need even lower position of the handlebar?
- How is ur saddle positioned in the rails in this moment? Is it in center? Is it on the rear edge? Or maybe front edge?
But this one u can adjust also picking different setback on ur seatpost (there is two options, 0 and 20mm setback)
- How much saddle u want to be show
Make one detailed picture from the side of ur current setup
so we can pick also based aesteticaly
And two more: One of the saddle position, one of the spacers part under the stem
Thanks for your feedback!
Yes I think 51.5cm or 50cm would be the best. But which one is the last question I have to figure out before I order it.
C60 48S: Reach: 383; Stack: 528; Top tube: 530
F10 51.5cm: Reach: 380; Stack: 527; Top tube: 535
F10 50cm: Reach: 374; Stack: 520; Top tube: 525
- Handlebar: I am actually fine with my current setup (C60 in 48S, 530mm top tube, 110mm/ -8° stem; no additional spacer). I don't have to go lower but I suppose that I could if I had to go lower (1cm lower with the F10 in 51.5cm and 1.25cm lower with the F10 in 50cm; with with a 110mm/-10° stem)
- Saddle: my saddle is in the centre at the moment but I have just swapped a new one and I have to set it approx. 1cm back
In terms of aesthetics, I like when you see "more" saddle seat post but on the other side a really too small frame (like the pro are using) just look "strange" to me.
So to me it looks like so in terms of the "figures"
- the F10 in 51.5cm would be like my current C60 in 48S BUT with a 0.5cm longer top tube AND a little less seatpost to see (-1.5cm).
- the F10 in 50cm would be like my current C60 in 48S BUT with a 0.5cm shorter top tube AND a 0.5cm shorter head tube (and therefore a lower handlebar position as I don’t want any spacer for „aesthetic“ reasons).
here the current setup (saddle has to go approx. 1cm back however):
The saddle has to go "back" approx. 1cm.
Sorry for later reply
, but beeing a bit busy could not find the proper time.
Ok so lets compare different sizes and as other said, it's not that important to compare just top tube length:
1. 47 Size Dogma F10
- Seatpost exposed - C60 in 48S have 48 cm seatpost tube. F10 in this size have 45.5 cm seatpost tube. So on F10 u'll have 2.5 CM more seatpost showing then on ur 48S.
- Stack - C60 in 48S have 528 stack, on F10 stack is 525, so very little difference. For me will be good option to have possability to go lower a little bit if it's needed. On C60 u can do it with lower headset cup if it's needed. Dont now how high is HeadSet Cup of Dogma F10.But i'l prefer 5mm spacer under the stem (or 10mm). So This size in term of stack can work (will be probably the same as u'rs in this moment).
- Reach - C60 have 383 reach, F10 have 373 reach. On F10 u'll have 1 cm longer stem then on C60, so instead of 110mm, ull have 120mm on F10. I had a chance to ride 51.5mm Dogma F8 with 120mm stem (im riding 53 FP3 with 110mm and C60 with 110 in 50S), and actually i like it.
- Saddle Setback
U are using 12mm setback seatpost on C60, and C60 have 74.58 deg setpost angle.
F10 have 74 deg setpost angle. If we put the seatpost on the side for a while, 74.58 vs 74 deg seatpost angle, means if they both have same seatpost setback, on F10 the saddle will be about 6mm in the front to get the same sadde position over BB. Now let's calculate with seatpost setback
on F10 u have two options: 0 setback, and 20mm setback
- 0 setback
To gain the same position as u have now , u'll have to put the saddle 12mm more on the rear.Let's minus the 6 mm from the seatpost angle now, so the real position will be 6mm more in the rear then the position u have now
Since u said u need ur saddle 1 cm on the back, the final position will look 16 mm more on the rear
- 20mm setback
To gain the same position as u have now, u'll have to put the saddle 8mm in the front. Let's add now the 6mm from the seatpost angle. So the abosolute position will be 14 mm more in the front then u have it now to have the same position.
U said that the saddle need to go 1 cm in the back? So when u put ur saddle 1 cm on the back, the final position will look 4 mm more on the front then u have it now.
2. 50 Dogma F10
- Seatpost exposed - C60 in 48S have 48 cm seatpost tube. F10 in this size have 48 cm seatpost tube. So on F10 u'll same seatpost showing vs ur 48S.
- Stack - C60 in 48S have 528 stack, on F10 stack is 520. That mean on F10 u'll have 8mm spacers under the stem to have the same stem position. For me this look like ideal, since u have both possabilities for adjusting. Going lower if it's needed, also higher.
- Reach - C60 have 383 reach, F10 have 374 reach. Since u'll have 8mm spacers under the stem on F10, the reach will shorten even more (like another 1 or 2 mm). So On F10 u'll have 1 cm longer stem then on C60, so instead of 110mm, ull have 120mm on F10.
- Saddle Setback
Everything i wrote about 47 will be the same for 50 as well, since they have the same seatpost angle.
51.5 can work for u as well, but aesthetically i prefer 47 or 50 (u'll have 1.5 cm less seatpost exposed, just 1 mm difference with stack u have now, so consider it the same. Probably here u'll go with 110mm stem and 80mm handlebar reach instead of 75 u have now)
From those two (or three), i prefer 50, since u'll have option for going lower if it's needed (5 mm stack difference), and the seatpost showing look totaly ok. The stem length and seatback identical between those two sizes.
There is the chart which visually explain what is what (i got mistaken first by CF and CC values of seatpost tube length):http://contenderbicycles.com/wp-content ... -Chart.gif
Hope i didnt make some mistakes in whole calculation, i'll try to find time to recheck later, but hope u are getting the idea to check with me again...
