Zero-offset post might help me run a longer stem on the 57.5 for steering and load, but stills feels like tinkering to make up for frame that's too big.
I'm always surprised when someone talks of changing the offset of the seatpost to adjust the ETT.

Isn't it true that you have to adjust the saddle to the right position first, and then play with the stem?
The saddle is set according to your leg and femur length, knee angle, KOPS (if you want to use it) etc. There is only one perfect spot for your saddle and moving your butt forward or back from that ideal spot can create other positioning problems.

Yes, this is true. The only things a zero offset seat post would achieve are the correct position for the rider if when using the setback seat post the saddle could not more any further forward and the aesthetics if it's on the limit.

Moving the saddle forward to fit a longer stem or to shorten the reach clearly shows that the frame is the wrong size for the rider.

A bike fit is highly recommend to achieve a the correct riding position.

Hi Phildhom,

I have got a Dogma 60.1 in size 54 and running a 90mm stem.

I'm about 175cm and saddle height is about 72.5cm. I think you might want to get fitted properly before you buy.

If I have a chance to buy again, I'll go half a size smaller - 53.5

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.

I'm 6 ft tall with a 32 1/2 inch inseam. I ended up on a 55cm 65.1 with a 100mm stem. I honestly could have gone with a 54 with a 110 or 120mm stem. But with my previous Roubaix having such a tall headtube, I wanted to keep the stem height/angle in check on the Dogma so went with the larger frame.

Hi there,
this is a amateur cyclist from Taiwan.

I have started a new tread asking about dogma sizing and then just found this thread.
Have been on my TCR advanced 2 (size:M) for about 6,000km.
Now considering a premium road bike for my next ride.
Happened to see a stock clearance of Dogma 65.1 in a local shop.
However, the only size they are offering is 51.5 (top tube:53.5cm)
My geo is as follows
Height: 178cm
Inseam: 85cm

I think i will definitely need a 13cm stem. Will such fit me well?
Look forward to your opinions. Thanks!

My Height: 71 inches
Bike Inseam: 32.5 inches
Arms: 28 inches

I ordered a frame with F8-like geo in size 55. The handle bar is a 420mm Bontrager XXX Aero.

Any recommendation on the stem length for a relaxed position?

I was thinking about a 110mm.

Thanks,
Desh
