Cervelo S3 size advice

Triathlon Forum

I am in need of some bike size advice. None of my local fitters are taking appointments, yet. I bought a Cervelo S3 online without testing one first. The store recommended a 51 cm in the aero road bike, but then shipped a 48 cm in error.
Before I send it back, I’m seeking alternative opinions on size. I currently ride a 48 cm P2. I’m 61.75 inches tall with a 30 inch inseam. The salesman in my LBS said he would have recommended the 48 if he had one.

Assuming you’ve had a proper fit, do you have a picture of the bike setup to your number, and a list of said numbers?

I have only been properly fit to the P2. Here’s the data for the P2 if it is helpful in providing advice on the correct size of an S3 road bike. And here’s a link to a video showing the results of the P2 fit: https://www.youtube.com/watch?v=vsSHNZiqDrc

Can you do me a favor and take this to the Official Cervelo Fit Assistance thread?

I know it says TT bikes, but I can do road too :wink:
