2021 Cannondale Synapse Carbon 105 Womens Road Bike in White

Season:2021

Brand:Cannondale

Code:C12371FIridescent

The Cannondale Synapse Carbon 105 Disc Womens Road Bike seamlessly merges a full carbon frameset with a sophisticated material layup, refined tube shapes and reliable components to make it the perfect choice for long and demanding rides across any road topography.

The carbon frameset utilises a high grade of composite material and lays this in a specific format to promote a ride that’s brimming with responsiveness, efficiency and strength within a lightweight form. The tubes of the frameset are realised via Cannondale’s SAVE technology to grant a certain amount of vertical flex for a serenely comfortable, fatigue-reducing ride experience, even across the roughest of road surfaces. Frameset clearance for up to 32mm tyres adds further comfort as well as increased control while an endurance inspired geometry places the rider in the ideal position for the longest days in the saddle.

Cannondale’s own RD 2.0 wheelset provides sharp acceleration thanks to its low weight but is also robust enough to counter harsh and poorly maintained asphalt. Gear changing is charged to the Shimano 105 setup, and this flicks through its wide range of ratios with accuracy and dependability. The matching 105 hydraulic disc brakes bestow confidence, even within torrential rain, thanks to their strong stopping power that is easily controlled by smaller hands via the short-reach levers.

The bike is crowned by mudguard mounting points that offer the potential for protection from cold road spray.



Key Features:
  • An incredibly comfortable but light and responsive road bike with a more composed geometry for the most enduring of rides
  • Full BallisTec carbon frameset is light for climbing and stiff for sprinting thanks to its refined tube shapes and dialled layup
  • SAVE micro-suspension technology in the frameset insulates from road bumps and vibrations affording better control and comfort
  • Clearance for up to 32mm tyres gives extra comfort and enhanced control across any road surface
  • Endurance Race Geometry positions the rider forward enough for efficient power transfer but upright enough for the longest of rides
  • Cannondale RD 2.0 Disc wheelset is reliable, strong and light
  • Shimano 105 11-speed gears are accurate and reliable
  • Shimano hydraulic disc brake set up bestows confidence inspiring stopping power and is easily controlled by small hands via short reach levers
  • Removable seatstay bridge and hidden mounts on the frameset allow easy installation of mudguards.
