If given the option of a 2006 Cervelo P2C and a 2009 QR Seduza, which would you choose? Componentry is similar between the two bikes; however, the Cervelo has DuraAce shifters and a few other upgrades. Thoughts?
Seriously girl- some very tangible differences in the geometry and fit of these two bikes.
That being the case, the choice is clear- get a good fitting done and go with the one that best matches your body dimensions. You won’t regret the difference a good fitting makes.
Both nice bikes, but one has a lower head tube per frame size and one has a higher head tube. One is a dedicated 76 degree seat tube angle and the other has the capability to go from 76 degrees to even beyond 78 degrees. Big, big differences.
If this type of information leaves you kind of cold you can do one of two things:
Go to a good FIST certified bike fitter to help you pick the best one based on fit.
-OR, do what most people do and… Pick the coolest looking one and rationalize why it was the best decision while you add headset spacers and swap saddle after saddle as you convince yourself *it must just be the wrong saddle… again. *
You;re smart enough to be posting here so I know you’ll do the right thing. Whichever way you go, enjoy your new bike and be safe!
Um, is the answer “The Pretty One”?
both nice bikes x2 on Tom’s post, whichever fits better an enjoy!
Tom -
Thanks for your thoughts! Seriously though, I’m approaching the bike purchase as I do running shoes - not paying attention to looks and trying to find the one that fits best.
Now, I’m even more confused about sizing after going to another bike shop tonight. I rode three 2008 QR bikes - XS Dolce, S Dolce and M Tequilo. Obviously, the biggest difference was between the XS and the M - but I couldn’t tell that much of a difference between the bikes - is that normal? Am I missing something here? The more bike shops I go to, I feel like the people there are just trying to sell me whatever they have in stock rather than putting me on a bike that fits. Tomorrow, I’m planning to go look again at the bike shop that did my fit on my road bike (a place w/ multiple FIST certified fitters).
There are really only 4 bar end shifters commonly specc’ed on bikes these days. Shimano Dura Ace, Sram carbon, Sram alu, and Campy Record. Of these the shimano DA is most likely to have the lowest OEM cost. So, when you say the cervelo has DA shifters you really mean it has the cheaper shifters. Makes me wonder what the QR has as shifters.
Assuming both bikes are new i’d go with the cervelo, simply because at the moment shops are selling the QR Lucero frameset at the same price as the P2C frameset. This sort of puts the Seduza in a lower price point.
Having said that, QR does appear to have a better fit range in the smaller 650c sizes.
“The more bike shops I go to, I feel like the people there are just trying to sell me whatever they have in stock”…
This is the first rule of retail sales…
Just gonna go out on a limb here, but I’m guessing she meant Dura-Ace derailleurs, rather than shifters.
Tom,
Thanks again for your advice. After riding both bikes, I realized how much more comfortable the Cervelo was. Then, after doing the measurements and looking at the sizing specs, I realized why. And, I also began to understand what you were talking about. I just didn’t feel as comfortable on the QR; to ride the bike with the right head tube length, I was riding the M (54ish?). (In comparision, my road bike is a 52, every tri bike that I’ve tried that has been close to fitting has either been a 51 or 52 and every 54 has been too big.) When, I was on that bike, it just okay at first; however, it just didn’t feel like the right size - just a bit too big. Strictly looking at the numbers and recommended sizing based on measurements (the fit guide from Competitive Cyclist), the Cervelo fell right in the middle of all my size ranges. I’m still a bit confused how bike sizing works (especiallly considering that I will be purchasing this bike from someone who is 2 inches taller than me); however, I now have a much better idea. Technically, I could probably make the size medium in the QR work based on the top tube length, right? But, it just wasn’t as comfortable as the cervelo. Rest assured, I’ll be going to a FIST certified fitter to confirm my assumptions and to get the bike in the right positions for me.
Thanks again!
Dan has a fit calculator on this site.
After my fit yesterday, the best bike for me would be a 58 cm P2C, or similar.
I would never have guessed that I would be on anything longer than a 54-55. (I’m ~5-11 and shrinking and have an inseam of ~33.5in)
I would pick the bike that is faster in the wind tunnel and find a way to make it fit
OR, find the bike that is cheaper and find a way to make it fit
OR, fine the bike that is most badass looking and find a way to make it fit.
HERESY!

That…is funny.
