Cannondale claims its SystemSix, built from the wheels up, can make anyone faster on two pedals.

Slow bikes are a drag — literally. And that’s exactly the problem Cannondale set out to conquer with the SystemSix. Launched today, the SystemSix represents Cannondale’s fastest and most aerodynamic road bike to date.
In fact, the Connecticut-based manufacturer claims the SystemSix is “the fastest road bike in the world.” And it’s the speediest bike on the market deemed legal by the Union Cycliste Internationale (UCI).
Cannondale SystemSix: ‘Fastest Road Bike in the World’
Components and materials have, for the most part, reached a plateau of efficiency. But, all other factors being equal, Cannondale believes the SystemSix will reliably beat out any other road bike. How can the brand make that claim? It all boils down to wind tunnel testing.
SystemSix: How Fast Is It?
- Fastest UCI-legal road bike on the market
- The least aerodynamic drag of any bike available on the market
- Faster uphill than any lightweight climbing bike, up to 6-percent grade
- Faster downhill: 33 percent fewer watts to reach 37 mph at 5-percent grade
- Saves more than 50 watts on flats at 30 mph
- All things equal (rider, conditions, etc.), will beat the fastest competition in a 200-m, 37-mph sprint by four full bike lengths
- Riders use 10 percent less power at an 18-mph pace
