Cannondale Synapse Carbon 105 Disc Road Bike 2021
Blending a full carbon frameset that has a sophisticated layup pattern with endurance inspired geometry and dependable, accurate components, the Cannondale Synapse Carbon 105 Disc Road Bike is the perfect partner for long and demanding sportives and the hardest training rides.
BallisTec carbon is utilised for the construction of the frameset and is laid with an intricate pattern to donate reactivity, strength and low weight. This carbon material is manipulated into sophisticated tube shapes via Cannondale’s SAVE technology concept and these grant metered levels of suspension over the roughest of road surfaces to preserve the rider’s energy. An endurance themed frameset geometry offers the perfect balance of control and power transfer, and this collaborates with generous clearance for wide, plush tyres to reduce rider fatigue and increase efficiency.
Cannondale’s own RD 2.0 Disc wheelset is robust and resilient to handle even the most poorly maintained of roads but is also light enough to surge up climbs with ease. The reliable and precise Shimano 105 configuration flicks through the broad range of gears effortlessly, and the partnering hydraulic disc brakes give confidence-inspiring stopping power in all riding scenarios.
The frameset possesses neat and discreet mounts and these work in tandem with the removable seatstay bridge to allow easy and stable mudguard installation for the wettest and coldest of riding conditions.
