Radar comes standard
Understated, clean graphics
Simple design with standard seatpost and threaded BB
Integrated SmartSense radar and light system
All-day ride comfort
Stable, confidence-inspiring handling
Good tire clearance (up to 35mm)
Shimano Ultegra Di2 12-speed drivetrain with wide range
SmartSense radar overly sensitive (cars two lanes over, parallel path traffic trigger warnings)
SmartSense battery charging finicky, needs resetting
Limited battery life (need to charge after every ride)
Wheels are heavy (1740 grams)
Lack of carbon seatpost reduces compliance

An overhauled endurance road platform meets modern all-road capability. It’s wonderful but there's a but.
Smooth ride quality, versatile tyre clearance, stable yet-not-sluggish handling, Shimano Ultegra Di2, easy to service component fitments, classy subdued styling.
SmartSense and the fact it’s a forced feature you’re paying extra for, wheels could be fancier for the money, mis-matched thru-axles.

Cannondale have overhauled the Synapse, adding an integrated radar and lights. Can it offer improved safety on the road? Read on to find out.
Added safety for cyclists
The lights switch from daytime to night mode automatically
Mounting points for mudguards etc.
Predictable handling
Lack of cable integration up front
Somewhat lacking in long-distance comfort

This is an initial score and could change as I spend more time on the bike
Cannondale's SAVE 'micro-suspension' is incredibly effective at taming rough tarmac and the low gearing and 32mm tyre clearance encourages more adventurous cycling
Messy cables up front detract from the otherwise clean overall design and the wheels and tyres are lacking modern endurance spec

The Cannondale Synapse Carbon 105 is a popular endurance bike that still has a spring in its step
Sprightly handling
Great at reducing road buzz
Solid spec
Good value
Heavy wheels
Frame probably due an update

A quick and versatile bike based around a great frameset, though the brakes aren't the best
