Shifting is handled by the brilliant Shimano 105 Di2 electronic groupset, now in its 12 speed version. Wireless operation means fewer cables and a more responsive, clean setup. With a 5034 chainset and 11 34 cassette, the gear range is perfect for endurance riding and varied terrain, from rolling countryside to punchy climbs. When it comes to control, Shimano 105 hydraulic disc brakes with 160mm rotors front and rear give you powerful, predictable braking whatever the weather. The bike rolls on DT Swiss R470 wheels, offering a great balance of strength, weight and smoothness, while Vittoria Rubino Pro IV 32c tyres provide excellent grip, comfort and puncture resistance. Theyre ideal for long rides, rougher tarmac or even light all road use. Rounding off the build is Cannondales C1 Aero 27 carbon seatpost, designed to offer flex and support while maintaining aero benefits. The Fizik Vento Argo X5 saddle is ergonomically shaped with a pressure relieving cutout great for spending more hours in the saddle. With SmartSense compatibility, hidden mudguard mounts and generous tyre clearance, the Synapse Carbon 4 is ready for everything from daily commutes to weekend epics.
