Summary

The Cannondale SystemSix is celebrated for its aero efficiency and versatility, offering a blend of speed, comfort, and aggressive design. It's noted for its stiff and fast ride quality, integrated aero features, and surprisingly comfortable geometry for an aero bike. However, some reviews mention limitations in downhill performance, comfort on rough roads, and the additional cost for power meter activation.

Pros
  • Fast and aero feeling on the open road

  • Versatile aero bike

  • Comfortable for an aero bike

  • Integrated package with well-executed internal routing

  • Surprisingly comfortable rear end

Cons
  • Downhill prowess neutralized

  • Wide aero carbon wheels may not survive long-term on rough roads

  • Power meter activation requires additional payment

  • Lack of comfort due to stiff frame, wheels, and narrow tires

  • Heavier and slower acceleration compared to competitors

Jul 2018 · Dave Everett
