Cannondale's Synapse Carbon 4 Rival features a fast, comfortable carbon fiber frame that mutes road chatter, weighs next to nothing, and features a ride-all-day position. The vibration-damping carbon fork and lively Fulcrum Racing Sport wheelset further enhance the ride quality so you feel fast and fresh. At your command are a host of quality components including an FSA/SRAM Rival 20-speed drivetrain that features a compact crank so you can conquer any hill, and powerful SRAM dual-pivot brakes for confidence on the descents. You'll also love the comfortable Prologo saddle and the Cannondale seatpost, stem, and compact handlebar.
