Eurobike 2013: Cervélo Rolls Out New S3 Aero Road Bike

Eurobike Road Bike

The new Cervélo S3 is a softer version of the S5 aero road bike at a friendlier price point.

Cervélo has revamped its S3 aero road bike and rolled out a more affordable version of its uber light Rca climbing machine here at the Eurobike trade show in southern Germany.

The updated S3 shaves weight from its predecessor and is now compatible with tires up to 25c. It’s also fairly affordable, hitting the market at $5,250 for Ultegra Di2 or $4,000 for mechanical Ultegra. Availability is set for December.

“There were some people out there that thought the look of the S5 was maybe a little too extreme,” explained Cervélo co-founder Phil White. “There was also issues with tire clearance and not being able to run 25s. So we wanted to address that and build on the great reputation that the S series already had, but make it a little less extreme. No, it’s not quite as fast as the S5. But it’s a lot more affordable and has a more subtle aesthetic than the S5. It’s a more classic looking road bike at a really good price point.”

Major changes include adjustments to the carbon lay-up and profiles of the fork and stays, which allowed for the wider tire clearance. The S3’s seatpost has also been simplified. Now the clamp is more central and easier to adjust.

Other S3 features include a dropped downtube that smoothes air from the fork to the frame and minimizes fork turbulence behind the fork crown; compatibility for two bottles; an extended seat tube cut out that further smoothes airflow; shielding seat stays that cover the rear brake; and a BBRight bottom bracket that has an 11mm increase on the non-driveside BB shell that allows for wider chainstays, seat tube and down tube.

There is also a new S2 that comes spec’d with Shimano 105 and will sell for $2,900.

Can’t afford an Rca? Me neither. But the R5 has many of the same qualities and wont cost you a half dozen mortgage payments.

Also new at Eurobike is the Cervélo R5, a bike White calls a Rca in production clothing. “The weight difference between the two bikes is minimal, about 140 grams,” said White of the two super light climbers. “And the R5 is still very comfortable with great stiffness.”

Pricing for the R5 is $9,000 for Dura Ace Di2, and $7,000 for mechanical Dura Ace or SRAM Red. Key features include a 1-3/8 steer rube, third generation squoval tube shapes, and ultra thin seat stays for higher vertical compliance and vibration absorption. The squoval tubes are squared and have more material the farther from the center you go to reduce side to side flex. Convex tube walls and rounded corners improve torsional stiffness.
