CERVELO RS 2010 FRAMESET $2,500.00 -
CERVELO RS 2010 ULTEGRA BIKE $3,600.00
Good enough for the pros (as proven by Cervelo TestTeam who raced it at Paris-Roubaix and the Vuelta a Espana), but don’t let that fool you. The RS is designed to give non-racers a bike that suits their style of riding, without the (unfortunately common) sacrifice in your performance experience. Thanks to its taller headtubes, the RS allows you to position your handlebars higher without needing too many spacers (or alternatively, to position your handlebars low with the use of a -17 degree stem).
DESIGN BENEFITS
2cm Taller Headtube - Allows for a higher handlebar position without requiring too many spacers (thus improving stiffness).
1cm Longer Chainstays - Compensates for higher handlebar position to maintain optimal weight distribution and longer wheelbase.
Squoval (Square Oval) Tubing - A square shape put lots of material far away from the center plane of the frame to create more lateral stiffness. The slight ovalization makes the shape extremely resistant to denting. The resulting frame is very light, very stiff and very strong.
Special XS Size - Optimized fit for the smaller rider with 650c wheels to create zero toe overlap (no chance to touch the front wheel with your toes).
SQUOVAL TUBING
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 Cervélo’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 Carbon
Patent-pending technology from Cervelo's carbon materials and manufacturing group, Smartwall™ elaborates on the Squoval tubeshape. With the sides far away from the center plane more important, Cervelo concentrated 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, Cervelo added Kevlar to the headtube/downtube area for industry-leading impact strength.
