The Cervelo R3 is not the most aero road bicycle (that would be the S3), it is not the stiffest (that is also the S3) but perhaps the one that is so light (sub 900 grams frame and fork), rigid, and vertically compliant. How stiff? Well, the secret check results of a positive massive bicycle company have found one of the laterally stiffest bikes to be the Cervelo R3 since it is release. How comfortable? Seven wins on the worst roads in professional cycling ; Paris Roubaix2006 and 2007. How light? The year Stuart O'Grady won Paris Roubaix he was riding a frame that weighed 860 grams.
When Cervelo set out to generate the lightest, stiffest bicycle in the world, they created a bicycle that looked unlike any other. Squoval Tubing, which is what it sounds like ; a square with ovalized corners, reed-thin stool stays, and a massive bottom bracket shell meld together to generate a bicycle that is as impressive to look at as it is to ride.
The Sqouval shape is ultra-stable laterally and resists torsional stress well, and when combined with high-modulus carbon allows for a lighter build without sacrificing stiffness. The top tube is Squoval formed at the head tube and stool tube junctions to combat lateral bending, and flows in to an oval shape in the middle where torsional resistance is more important. The down tube is Sqouval tubing from head tube to bottom bracket, where stiffness lives. Massive Squoval chain stays keep flex out of your ride. Integral to the performance qualities of Squoval is Smartwall for Carbon Expertise, which the R3 proves is relevant to all tube shapes, not the ultra-aero tubing of Cervelo's Soloist and time trial sleds. Fine tuning the wall profile and carbon lay up of Squoval tubes allows Cervelo's engineers boundless control over qualitative features like ride quality, and quantitative characteristsc such as durability and rigidity.
For 2010 the Cervelo R3 received a facelift and new parts package. The wheels are now Fulcrum Racing 5 and the part package is Shimano Dura Ace 7900.
