Now according to Cervelo issues are arising with the Campy Super Record Gruppo on the new S3. The Campy Super Record on the S3 may or not fit. It will fit some S3 frames and not fit other S3 frames. It is apparently luck of the draw. Cervelo also states that most Campy wheels will not fit the S3. After this I am giving up on the S3. I will wait until they get the issues worked out. Below is the Cervelo email to me and my earlier email to them asking questions.
Tolerances on the Campy Super Record Groupo are very tight. Some frames do not have issues and some do. The best thing to do is have the shop you purchase your S3 from test the frame before they sell it to you. In doing that you will ensure you components will fit before you pay for the bike.
As for the wheels it all depends on the hub. It is impossible for us to test every wheel, from every company, from every year. If you measure from the axle lock nut to the outer most surface of the non drive side spoke, at a measurement of 22 mm forward from the axle center, anything less than 30 mm might be an issue. Still the rider’s weight and riding style will play a factor as both affect how much the wheel will flex. Most Campy wheels are not compatible with the S3 however.

I am in the process of placing an order for a Cervelo S3. Is a braze-on front dérailleur the correct one to use? How well does the Campy Super Record Gruppo work with the S3? Do the Edge Composite Wheels 38 Clincher, 41 mm, fit the S3? Thanks for making great bikes.
