Many road riders these days want a bike that is versatile and can handle many different conditions. Whether you're riding smooth bike paths, cobblestone roads, or roads that haven't been paved for several years, you'll want a bike that will keep rolling. The Cannondale Synapse Carbon 4 Bike is a smooth, fast, and confident road bike that is perfect for a wide range of riding. The lightweight carbon frame has discreet flex zones in the rear triangle, seat tube, and seatpost that absorb road chatter and bumps without adding weight. The frame also features internal cable routing, clearance for up to 35mm tires, hidden rack/fender mounts, and thru-axles.
The 2 version of the Cannondale Synapse comes with a Shimano Tiagra 2x10-speed drivetrain. With a 50/34T chainring combo up front and an 11-34T cassette on the rear, you'll have no issues climbing steep hills or going out for all-day adventures. Shimano Tiagra hydraulic disc brakes provide excellent stopping power so you can descend with confidence. RD 3.1 28h rims are paired with Vittoria Zaffiro Pro Reflective 700x30c tires.
