Rider Position / Bike Geometry

A true cross country race position. The geometry will flatten your back but keep your arms relaxed for shock absorption and still in the pefect angle to help in the steep climbs.

Innovation AND Technology

Ballistec Carbon Frame

BallisTec is Cannondale's proprietary method of high-strength, high-stiffness carbon construction. It is the ideal blend of the most advanced materials in the world combined with the most advanced carbon engineering and design.

The results speak for themselves.

Asymmetric Integration

Ai, our Asymmetrically Integrated Drivetrain System, allows us to create bikes with ultra-short chainstays for traction, handling and stiffness, without any of the usual compromises in clearance or limited chainring options. And as a nice bonus, it creates a stiffer, stronger rear wheel as well.

System Integration

We pride ourselves in making the most kick-ass, cutting edge frames in cycling. But you don’t race a frame, you race a complete bike. It seems like common sense, but we stand alone in the industry with our System Integration approach to bike design. Cannondale Si approach incorporates our cutting edge frame design with custom designed Cannondale forks, suspension and drivetrain components.

This unique complete-bike design and build approach ultimately delivers the best performing bikes possible.

SPEED SAVE

Race‐oriented SAVE features. Much like the suspension on F1 cars, SPEED SAVE features are engineered to help the bike roll faster, not simply to make it more comfortable. Emphasizing light weight and torsional rigidity, SPEED SAVE delivers improved rolling speed, better acceleration, and dramatically improved cornering speed without negatively affecting power transfer.

SAVE features for everyday riding.

Simplified SAVE technology engineered for our alloy bikes. Whether hitting a pot hole, dodging obstacles on city streets or chasing the field in a crit, SAVE features are designed to remove the harshness, protect you from energy-sapping vibration and improve ride comfort.
