About the productCannondale Synapse 105 Road Bike 2021

Brief description

If you’re after a bike that will allow you to go a long distance without sacrificing any comfort whatsoever, the 2021 Synapse Women’s 105 is just perfect for you. A bike that’s light, stiff and fast, yet surprisingly comfortable, and allows you to ride as long as you want to. With a ladies-specific frame and a reliable choice of components, the Synapse 105 is the go-to bike for the ladies who want to go further.


Detailed explanation

Cannondale’s 2021 Synapse Women’s 105 is their go-to endurance road bike. The SmartForm C2 Alloy frame comes with their SAVE micro-suspension technology to get you even more comfort and vibration absorption, without compromising on the stiffness that keeps you rolling fast. You’re also looking at internal routing for the cables, as well as a BallisTec full carbon fork that keeps weight low without sacrificing comfort.

The drivetrain is taken care of by Shimano’s extremely reliable 105 road groupset, in a 2x11 configuration. The compact FSA Gossamer crankset has a 34/50 chainring configuration, which combined with the 11-34 cassette at the rear, have you covered in any scenario, from fast flats to steep hills. TRP’s Spyre-C mechanical disk brakes take care of braking as well.

The wheels are Cannondale’s RD 2.0 Disc rims laced on Formula hubs with a thru-axle at the front for added stiffness, and a QR axle at the rear. They come with Vittoria Zaffiro 30c tyres, which are thick and provide a bit of extra comfort when you’re out on longer rides. Round this out with Cannondale 3 series stem, seat post and compact handlebar, as well as their Stage Ergo Women’s saddle, and the Synapse 105 becomes a great choice for an endurance road bike for the ladies.


Technical features:

  • SmartForm C2 Alloy frame with SAVE micro-suspension provides plenty of comfort, allowing you to go further, faster.
  • BallisTec full carbon fibre fork lowers weight without compromising on performance or comfort
  • 2x11 Shimano 105 drivetrain with mechanical disk brakes is very reliable and low maintenance.
  • Vittoria Zaffiro 700x30c tyres give you a bit of extra comfort on longer rides, absorbing vibrations from the road.
