Cannondale

Cannondale's lightweight, fast Synapse Carbon Ultegra Di2 blends voracious speed and sublime comfort for a bike that's primed for centuries, Gran Fondos, and days spent exploring the roads less traveled. The lightweight carbon frame and tapered carbon fork employ Save Plus shaping to ensure a compliant ride that soaks up road buzz, while the endurance-oriented women's specific fit ensures hours of comfort and a slightly elongated wheelbase provides stability on descents. Once you get a taste of Shimano's 22-speed Ultegra Di2 electronic drivetrain you'll be a believer for life. Unbelievably fast shifts—under any pedal load—are yours with the simple push of a button. Mavic Aksium Elite wheels climb with ease and accelerate effortlessly; they're paired with durable Mavic Yksion tires, so you can pin every corner and curve on your favorite road loop. And, Shimano's powerful Ultegra brakes boast as much smooth, controlled stopping power as you could desire. Cannondale pays attention to the details as well, with a Fizik saddle and their ultra-light aluminum and carbon components, for a fit and ride that will leave you wanting to go farther on every ride.
