Hello,
I want to buy the same bike. I'm 1m75 and i have a saddle height of 70 cm. i seen that you have a 54 with a 90 mm stem. I had for myself a 50 in mind.Is a 54 not to big?
Hi Phildhom,
Every bike fitter will tell you a different fit. I have recently gone with a very reputable fitter and thus far his advice worked for me.
I felt that 54cm is a good size for me because I have tried various bikes (not Pinarello) ranging from 53cm to 56cm. So how 54cm fit a lot better than the other 2. The 54cm Dogma 60.1 gives me just enough head tube height so I don't have a funny looking stem style, it feels a lot more stable around the corner and in terms of cockpit space, it feels just right for me (i.e. 53cm - too cramped and not enough head tube height. 56cm - too stretched and I don't have much control over it).
The reason that I run a 90mm stem is because my arms are approximately 2cm shorter than your average person (i.e. 84cm vs 86cm).
For your information, I'm in the process of purchasing a Colnago C59, the geometry that I'm going with is a 50 sloping, which equates to a 53.5cm. I'm hoping that I can run a 100mm or 110mm stem to dumb down the responsiveness and reduce the reach slowly for climbing.
Also, you will need to bear in mind that each Dogma series has different geometry. You will need to check carefully before purchase. From memory, Dogma 2 and Dogma 65.1 are slightly longer than the 60.1.
Furthermore, to throw the spanner into the work, I also have a Pinarello Quattro (commuter), which is a 55cm geometry. My fitter have managed to mimic the setting on 60.1 and transfer it across. It felt exactly the same, in terms of bike setting.
My advice to you would be go and visit a number of reputable bike fitters. Have a chat with them and see who you are most comfortable with and get a bike fit down on the jig before pulling the trigger on a expensive bike.
Hope the above helps you with your decision making.
Below is the photos of my 2 bikes. The 60.1 is on my finally setting. The Quattro is before the setting.
