Pinarello Prince... size advice needed (v important for me!)

Tim F

Hi all,

I'm after a 2008 Prince however it's really important I get the right size. I'm 5 foot 6inch. Not sure if I need a 51.5 or 53.5!! Sorry for the crazy question but I can't ride it to find out. I know they have long top tubes so any advice would be MUCH appreciated.

Many Thanks, Tim

What size bike you need depends on loads more than just your height.

Yep I know that, I've been through all the pro measuring programs which say 52cm however this is a tricky one so looking for Prince owners that know about the longer top tube and have experience of the model.

Ta, Tim

Yes but another 5'6" Prince owner won't necessarily take the same size as you.

You have given no mention of your:

-limb/torso lengths
-flexibility
-riding style
-sort of fit you want.

TBH I'd recommend going to some one who'll do a proper fit for you, and nail everything down.

Based on what I know of Pina I would say the smaller frame set as the odd thing about Pina is that the slight dip at the end of the top tube towards the headset makes the bike seem longer than it is. I would say 51.5 to be honest. I have a 54 Pinarello FP3 which is more like a 55 'any other brand.'

If in doubt (as you are) you'd have to go for the slightly smaller size. More seatpost and slightly longer stem can sort it out.

Can't you just use the top tube length as a guide? I've got a 2008 Prince, which is a 55, but this obviously relates to the seat tube measurement, not the top tube. TT length is 55.7cm.
I'm not sure I follow the argument about Pinarellos having longer top tubes. The Prince is 3mm shorter than my Time. Maybe people are confused by the fact that the sizes relate to the seat tube?

Straight up? I did not know that. If you look at the Pina spec sheets, I have always assumed that it is based on the top tube. If you are saying what you are saying and its correct, then thanks for the heads up. I never knew that. I have a 54 cm Pina that fits very well but as I said, the top tube is 55. Thanks.

Thanks all very much for the advice. Thought I'd better be a bit more careful here so took some of your advice!! Here's the full info... should help get some accurate advice as I'm still not clear. Looks like I should be considering a 50 which isn't available. Riding style will be agressive.

Did you take those measurements yourself or get someone else to do them with a spirit level properly?

Looking purely at the numbers you seem to be freakishly disproportioned.
You have a short in-seam but have humongous thighs and calves. Doesn't add up.
I compared with my numbers and I am 10cm taller but am quoted a similar TT and a 10cm lower saddle hight. I have a very long set of legs for my hight too. Usually TT reach is a problem for me and I end up with a massive saddle-bar drop.

Lol I'll recheck....

"Looking purely at the numbers you seem to be freakishly disproportioned.

Don't think so having had another look. If you follow this on the size chart... perhaps 59cm on second measurement....

Sit on a stool again making sure your back is straight and your pelvis is hard against the wall. Make sure your femur is parallel to the ground and your tibia is perpendicular to the ground. Place the level across the front of both of your kneecaps, then measure from the inside face of the straight edge to the wall. Take this measurement from both legs, then take the average.

There are pictures on the site as to how I measured this. I'm pretty normal I think!
Ah yes on the top tube I'm also confused about this. Previous calculators have suggested at 52cm one so something doesn't add up!

I agree, it doesn't really add up.

The fit recommends a 51cm seat tube with a 56.5cm TT. Thats a wierd looking bike
