Pinarello sizing help please?

Hi Guys,

I am looking at the FPQuattro and they have 53 and 54.

My current bike which fits me great has a ETT of 54.3 cm, and a head tube of 15 cm. I use 4, 5mm spacers for a good fit, and my saddle is half a cm pushed back.

The 53 Pina has 54.5 and a headtube of 14.4, while the 54 Pina has ETT of 55 and headtube of 15.2.

I was originally looking at the 53, but now am thinking of the 54. A friend says that the 54 is a really big bike, and his partner who is 6'2" rides one. I am only 5'8" but with long legs. Inseam is 82.5cms [32.5 inches]. I think his partner rides a smaller frame for an aggressive fit, while I could have a relaxed fit on the same size.

No chance to try at all, and this will be a online purchase. Suggestions?

Some help guys. Is the 54 going to be so much bigger than the 53?

Well, I don't know this from personal experience, but my friend who is a Pinarello dealer told me within the last year that most people go to a smaller size in pinarello frames compared to others. (They run big). If I were you, I'd go with the 53 over the 54. I think you're generally better off with a smaller frame anyhow. You do enough riding that you deserve a better frame than that generic Chinese frame you were riding. Good choice, and get well soon both to you and your wife!

Per the size chart, they have the exact same reach, and 1 cm stack difference. Remove two of your planned 5 mm spacers and they are identical. If you know someone who is 6'2" riding a 54 they must like a seriously tiny bike. Granted, body proportion makes a huge difference, but I am slightly taller than that and the 54 is way out of any appropriate park.

Either one should be fine. You have room for another few mm of spacers if you need. You don't mention what length stem you use, but that is a factor too. If your current stem size is short, i.e. 100 mm or less, then definitely go with the smaller frame. If your current stem length is long, say 120 mm or more, then go with the longer frame. Either of those choices may force you to buy a more medium stem, like 110 mm. Those characterizations are just my opinion, but I think you get the idea. Don't just use top tube and head tube measurements, but also the reach and height that your stem adds to it. There are online calculators for this. If you are riding a 110 mm stem already, I would say either frame could work well. You may have to fine tune the fit by flipping the stem in any case. By the way I am close to 5' 8" and have always ridden a 54 cm frame in any make. My stems range from 100 mm to 120 mm depending upon top tube and seat post set back (another factor since I slam my saddle all the way back anyway).

One additional comment. You said you are buying a Pinarello online. I would just remind you that Pinarello is one brand that is often "faked" by Chinese manufacturers (aka Chinarello). Please take care that you are buying from an authentic and reputable supplier.

Thanks for the wishes. Yes, we both had bad crashes within 2 weeks. She had a head injury too.

That's what I thought too.

I'm using a 100mm stem now, but could do with maybe 110. I just thought that with the bigger frame, my saddle could be neutral, and I could have a taller head tube with less spacers.

Have mailed Pinarello and they have confirmed that he is a genuine dealer. In Germany so unlikey to sell fakes I think.

Your number of spacers is quite conservative in my opinion and gives you room to add or subtract. Going lower could box you into a corner, but probably not. You don't want to have to go lower than a 100 mm stem in my opinion. You will get better bike control with a longer stem. I think I would go with the smaller bike and a 110 stem. The added length will add some to the height. You won't likely need more than one more spacer. That is just 25 mm or 1 inch altogether. All my bikes are set up with at least that much. Some folks don't like this, but it doesn't bother me. And BTW you know you can reduce the apparent number of spacers by substituting a higher profile top member on the headset such as a domed version.

Pinarellos anyway come with a 15mm topcap, while my current topcap is 7mm, so Pina 53 with 14.2+15mm is same as mine which is 15 headtube + 7mm topcap.

Just got a mail though and the 53 is no longer in stock in the deal price, they have the 54 with a 135mm stem. If they can get me a 100 stem I'll buy it, else I'll start looking again.

Issue is shipping to India means 250 dollar shipping PLUS 45% duty, so I need to look where someone ca carry it back for me. Otherwise a 3000 dollar bike becomes 5K landed.

Well, your decision is now obvious. Sounds like you have it under control. Can you pay to reserve the 54 cm bike so it also doesn't sell out and have seller hold it while you find someone to bring it back for you? Can you buy a 100 mm stem and later sell the 135 if dealer won't make the switch for you? Perhaps the stem is a special match for the appearance of the bike and would be hard to duplicate. But it is strange for the bike to come with a 135 mm stem. Not only is it incredibly long for the size, but most companies don't even offer such "half" sizes (not even cm) any more. Sounds like a switch has already been made somewhere along the line. Have you thought of combining the bike buy with a vacation? That would be a much better way to spend the extra money than on shipping and duty. Good luck.

I can't buy a bike on vacation, even though we travel twice a year to Europe, as we carry bikes from here. Maybe next time, I will buy there but there are logistic issues, as we carry folders for travel.

The dealer said that he can give me a 100mm stem, but in black.

My friend uses a 53, and his saddle height is 73cm. My saddle height is 75cm, even though he is marginally taller than me, as I have a long inseam.

Here is the pic of the bike for sale.

And here is my friends bike showing how much seatpost is showing. He rides a 53 with a 55cm seat tube, while if I buy the 54 the seat tube will be 56cm. However my saddle will be more than 1.5cm higher than his, so I should have at least the same amount of seatpost showing.

Got the 54, and it's a great fit. Happy I did not go the 53 route [not this deal, but was also looking elsewhere]. Could have fitted the 53 too, but saddle would have been further back, and I would have needed one more spacer.
