Highlights

Squoval downtube and chainstays - Optimized for the highest possible stiffness-to-weight ratio (STW).

Multi-shape toptube - Squoval at both ends and oval in the middle to counter the complex loads.

Oversized bottom bracket area - Large diameter and smooth, optimized shapes increase bottom bracket stiffness for excellent power transfer from pedal to rear wheel.

Lay-up optimization - Approximately 300 pieces of carbon, each optimized in shape, fiber type and fiber direction.

p>Leaf spring Seatstays - Unparalleled vertical compliance thanks to their leaf spring design.

Higher handlebar geometry - Same handling philosophy as our other road bikes, but with longer headtube for those who prefer a higher handlebar position, and longer chainstay length to keep the weight distribution balanced.

Special XS size - The new XS size completely eliminates toe-overlap (see geometry section for more information).

Squoval

The dominant forces on the downtube and chainstays are lateral bending forces. The best way to resist those is with a lot of material far away from the center plane. Square tubes do this best, but can easily buckle. A slightly ovalized square creates the best of both worlds, which explains why Cervelo's Squoval shaped frames win stiffness and lightweight tests everywhere.

The front and rear of the toptube also use the Squoval shape to counteract lateral bending, but it transitions to oval in the center to counteract the torsional loading in that section.

Smartwall for Carbon

Patent-pending technology from our carbon materials and manufacturing group, Smartwall elaborates on the Squoval tubeshape. With the sides far away from the center plane more important, we concentrate more material there to increase the benefit.

Strips of High and Ultra-high modulus carbon stiffen the sides of the main tubes to resist lateral bending. These strips are feathered in to properly transfer the loads from the joints into these tubes.

Finally, we add Kevlar to the headtube/downtube area for industry-leading impact strength.
