SYSTEM SIX
The only trend we care about is winning. That’s why we use high modulus unidirectional carbon for the front triangle. Ultra-light, race-proven aluminum for the rear. Ingeniously melded through a proprietary, continuous-fiber lay-up technology. The proportions are huge. The design is obsessively tested. And the result is the lightest, stiffest, most explosive bike we’ve ever made. The new SystemSix—winning never goes out of style.

 

Si

You don’t ride a frame—you ride a bike! At Cannondale, our System Integration philosophy is holistic. Our latest example: the SystemSix fork, stem, headset and head tube have been designed as an integral unit. The result is superior front end stiffness and clairvoyant steering response.

OPTIMIZED TUBE SHAPE

The massive head tube perfectly accommodates the radically oversized down tube and ovalized top tube. The top tube shape provides superior lateral stiffness, while the down tube is designed to resist torsional flex. The result? You pedal, you go. Fast.

CANNONDALE Si HOLLOWGRAM CRANKS w/ SRM

The SystemSix Team Si SRM comes equipped with our Si Hollowgram cranks with SRM power measurement—which still weighs in lighter than the industry benchmark crankset.

OPTIMIZING MATERIALS

The SystemSix front triangle is co-molded to a CAAD9, aerospace-grade aluminum rear triangle. The seat tube is double-butted for lightweight stiffness, while the elegant hourglass seat stays and oversized chain stays provide a touch of compliance without sacrificing lateral snap—perfect for out of the saddle sprinting or climbing.
