Technology

Wide Ranging Capabilities

With full clearance for tires up to a whopping 32mm wide, and subtle, hidden fender mounts, the Synapse is ready and willing to explore the wilder side of endurance riding.

Power Pyramid Seat Tube

The seat tube splits asymmetrically to meet the wide, 73mm BB30A for maximum stiffness with minimal weight.

BallisTec Carbon

Cannondale's proprietary high-strength, high-stiffness carbon construction. An advanced matrix of intermediate modulus fibers creates a frame that's light, durable and lively.

Fender Up

Fully fender ready. A removable fender bridge on the rear stays is there when you need it, gone when you don't.
