Cannondale Synapse Carbon Ultegra Disc Road Bike 2021
Featuring an endurance inspired geometry that is brought to life via an advanced carbon construction, the Cannondale Synapse Carbon Ultegra Disc Road Bike is the ideal steed with which to tackle the toughest of gran fondos and the most enduring training rides.
A responsive and enthusiastic ride sensation is infused naturally into the frameset thanks to its stiff but lightweight carbon fibre composition. A nimble climber and adept sprinter, this frameset truly excels when confronted with rough and fatiguing road surfaces thanks to the metered levels of suspension donated by the integrated SAVE micro damping technology. This suspension technology partner generous clearance for wide, plush tyres to increase comfort and preserve rider energy levels on the longest of days in the saddle. The frameset is realised with a composed geometry that bestows composure within technical riding situations but is also reactive for the most challenging of descents.
The Fulcrum Racing 600 wheelset is light and lively but also strong and robust to give a confident and inspiring ride. Shimano Ultegra gears are ever reliable and accurate to always allow the perfect cadence to be selected while the matching hydraulic disc brakes grant modulated stopping power in any weather conditions.
The bike is crowned with neat frameset mounts and a removable seatstay bridge to allow trouble-free and secure installation of mudguards for when the weather is truly foul.
