Become a steward of the road less traveled with Cannondale's Synapse Carbon Ultegra 4. Cannondale's Synapse Endurance Race Geometry offers a comfortable, efficient ride that appeals to Gran Fondo specialists, century riders, and folks who love the thought of riding into the sunset. To do all that and more, the Ballistec carbon frame transfers power smoothly and damps road vibration, while Shimano's 11-speed Ultegra drivetrain delivers unbelievably fast, easy shifts with the flick of a finger. A Cannondale Si crankset transfers all your power to Mavic's Aksium wheels, which are the perfect pairing for this endurance machine. Matched with Schwalbe Lugano tires, you're primed to sail through every corner and curve on your favorite road loop while Shimano's Ultegra brakes redefine rim brake power. Throw in a sleek, supportive Prologo saddle and a batch of Cannondale's own prime components and you've got a bike that will have you chomping at the bit.
