Pinarello Paris size

igor-jz · Nov 11, 2006

Hi!
Maybe anybody knows the size of the Pinarello Paris Carbon measured from the center of BB to the top of the seat tube, if that frame has 53 cm c-c? And what is this size for 51.5 cm frame? I going to buy that frame, actually my size is 53, but Paris 53 seems biger...
I would be very thankful with the answer.

Hi Igor,

Not sure if I fully understand your question, but maybe this will help. The Paris Carbon "sizes" listed are c-c sizes (measured center of BB to center of top tube). The 51.5cm frame (c-c) has a top tube of 53.5cm. For reference the 50cm frame has a 52.5cm top tube and the 53cm frame has a 54.5cm top tube. Some consider the Paris top tubes to be a tad long as compared to other manufacturers similarly sized frames.

Check out Pinarello.com for all the geometry info. It's not actually listed on the website, but available as a pdf download if you navigate to Bikes\Racing\Paris Carbon\Specs.

Good Luck

Thanks, but this is information I actually know...
My Pinarello Prince frame 53 cm has steerer tube 13,8 cm. The Paris Carbon frame I want to buy (same 53 cm) has it 15.3 cm (as displayed on Pinarello's web). The question is how the frames with equal size c-c can have different steerer tube sizes? Which means the Paris Carbon 53 cm is biger... Because I live in Moscow (Russia) where actually are no dealers of Pinarello, I can't verify this. That's why I asked such a question - maybe anyone has that frame and can tell me the size...

OK - I'll try once more then. I'm all but sure the that the head tube lengths listed are correct. I can tell you for a fact that the 56cm frame has a 180mm head tube as specified, as I own one. I think I understand your question regarding the same size frames having different head tube lengths. Assuming they are both level top tubes, I can think of a couple of factors that would account for this. 1) the diameter of the top tube is larger necessitating a longer head tube to "clear" the top of the top tube. 2) They purposely terminate the head tube 1cm - 2cm above the top of the top tube (sometimes called a head tube extension) in lieu of a fraction of a cm above the top of the top tube.

I've never sent Pinarello an email, but I hear they are pretty good about responding (although not real speedy). I would try emailing Pinarello and asking them how they managed to build two frames the same size c-c with different head tube lengths.

Sorry I can't be of more help to you.

Thanks for responding...
That's a good idea - if the top tube larger in diameter, the lenght of the head tube will be probably larger too...
The point is that I need to choose which size of Paris frame is going to fit me properly - if 53 cm Paris is biger that my Prince 53 cm, then I have to go down to 51.5 or something else...
Anyway, thanks for good advice!

You need to check the charts, but IIRC (I haven't got my bike here to measure it), the difference between the size measurement and the top of the ST collar is 3.5cm (my size 54 is actually 57.5cm centre to top of ST).
You need to add another 1.5cm to the HT stated, because Pinarellos come with a headset collar of that height that cannot be changed (they come with the forks already installed and the headset pre-tensioned, the only thing that needs to be done is install the stem and cut the steerer once you've set the correct bar height).

The end of the story:
Because I was in doubts of wich size I actually need (53 cm as my current Prince or 51.5 cm), finally I have made a phone call to Pinarello's factory. I had a funny convercation with some girl, who tried to help me. She spent a lot of time trying to understand what I need from her... At the end she sent me a letter to my e-mail: "We recommend you to take a 53 cm frame, because if you will buy a 51.5 cm frame, you will need to have a 1 cm longer stem..."

However, I did my own research and have found that all new oversized carbon frames of Pinarello went up in sizes: if you currently ride 53 C-C old frame, you have to go with 51.5! The 54 fits more like 55! When you are looking at the pinarello's geometry table, keep in mind, that you have to add 4 cm from the center of the top tube to the top of seat collar (at least with 51.5 frame). May be this information can be helpful for somebody else...

P. S. Finally, I have purchased a 51.5 Paris carbon. It has got 55.5 cm seat tube (measuring C-T!!!). My Prince has 56 cm (53 C-C), but this difference you can adjust with the stem and seat post.

If you ride a 53 c-to-top normally, it's best to go with a 51.5 Paris Carbon. The standover height won't be as good though. If you are racing, it's best to go one size smaller at 50.0, but you'd have to use a pretty long stem. The Pinarellos are famous for largish tubing and tall headtubes. Wrenchscience was selling a frame on Ebay that they had to strip: it turned out too big for a customer, in terms of standover height (even they got it wrong).

Actually, Pinarellos have SHORT top tubes compared to other frames. For example, a 51.5, which would be equivalent to a 53 c-to-top otherwise, has a 53.5 TT, same as on a 53 cm C50. And everybody knows the Colnagos are famous for short TTs.

And interestingly enough, the Paris Carbons in smaller sizes such as 51.5 have just as slack head tubes as a Colnago C50! Around 71.3 degrees or so. Most race bikes use 73-74 head tubes. The larger sizes get steeper head tubes.

Hi, Clevor!
My previous Prince is not 53 c-to-top, but c-to-c. The problem was of choosing the right size for the new Paris I wanted to buy. I agree with you - for racing machine a bit smaller frame is better.

i have always ridden a 55cm top tube so when i bought my paris i got a 54 cm (the size with a 55cm top tube). in that respect pinerello are very acurate - when they say it has a 55cm top tube, it does.

i think it is personal to the individual but i have chosen all my frames on top tube length and they all fit perfectly; i'm not sure why you would worry about the seat tube length - would someone enlighten me?

igor-jz · Jul 10, 2007

poshscot,
a good question, by the way!
But keep in mind that different issues of Pinarellos have different ST/TT measurements, and in my case it would be reasonable to concern with ST. Because the TT lendth for both Paris Carbon and my current Prince (53) were about the same (mere 2 mm difference), but the ST has got completely other story... By the way, the same difference with HT (138 mm of my Prince vs. 153 mm of Paris Carbon) can make huge changes in your overall fit for the bike...

I recently bought a Paris on line using the dealer's fit calcualtor and determined that I needed a 51.5cm frame. When I received the bike, it did not have quite the top tube clearance that I had hoped and is actually quite little. I went ahead and kept it (avoiding the 10% restocking fee and maybe another long wait for a 50cm frame) and had it fitted at the LBS. He told me it looked a little big as soon as I rolled it in the shop but said it would probably be ok with fitting. Riding it feels fine except for the fact that I'd prefer a bit more top tube clearance. I am a recreational rider and do not ride competitively. Do you think that the 50cm frame that is 1.5cm smaller and 1cm shorter on the top tube would have made that much of a difference for me as a recreational rider? Should I have sent the 51.5cm back for the 50cm?

Hi, garmjoe!
First of all, I would'n recommend you to use a fit calculator to determine the frame size you need. It can give you some info - more or less, but not as precise as you want...
What is the frame size you are acually riding?

garmjoe · Jul 11, 2007

Hi igor-jz.
Thanks for your response and feedback. My Paris is a 51.5cm frame. I must admit I probably could have done more due diligence prior to making such a large investment but what's done is done. I had tested two other bikes in a 51cm and they seemed to have more than enough standover so when the results of the fit calculator came back that the 51.5 would be the size for me I thought great, what's .5cm going to make. There is some standover height for me, but that little bit did make more of a difference than I thought it would....the 50cm would have been probably better for me. And then after seeing all the professionals riding on smaller frames it just got me to thinking if my bike is way off...but then again as a recreational rider I don't think I require that kind of riding position/reduced frame size.........thanks for your feedback....

garmjoe:
As I think, if you really love cycling & bikes, you probably won't be regret of the investment you have done!

The question is, as I figured out, which frame is better for you - 51.5 or 50. That's why I asked you, what frame size have you currently been riding (before you purchased your Paris - sorry, English is not my home language, so may be I wrote not so clearly

). The goal is if you have been riding other frames in size 51 (I am talking about classical frames C-C), with new Pinarellos (specially carbone frames) you have to go one step down and choose 50 cm frame for THE SAME FIT - this is the issue of all my posts here!
Keep in mind also, there should be aprox. 13 cm of seat post exposed above the TT of the frame - that's can indicate (more or less) that frame is good for you. And doesn't matter, if you are professional or recreational cyclist - I think your bycicle should fit you properly so you could feel comfortable and enjoy riding...

thank you again. sorry i misunderstood your reponse. actually, i have not had a road bike since college (about 15 years ago) and do not recall what size I had then. I have been riding a mountain bike since then. I turned 40 earlier this year and decided to treat myself to something special in the Paris Carbon. I should have been more diligent prior to my purchase I know. So far I feel pretty good on my bike...perhaps it's just all the articles on "what size your bike should be" that has me second guessing myself. The info you have provided is great and I'll check out my seat post when I get home. Happy riding to you!
