The perfect do-it-all bike for the modern road cyclist, the Cannondale Synapse SM 105 Road Bike 2017 is just as comfortable on long audax rides as it is on tight circuit races. With the S.E.R.G. Race Endurance geometry, Shimano's 105 components and Mavic's fast rolling Aksium wheelset, this bike is more than ready to roll.

Cannondale Synapse SM 105 Road Bike 2017

If you want only want to buy one bike, the Cannondale Synapse SM 105 Road Bike 2017 is the one for you. A bike more than up to the task of delivering an engaging ride, whether that be racing, sportives or commuting. Offering the comfort of a tourer with the speed and weight of a lightweight racing bike, the Cannondale Synapse SM 105 Road Bike 2017 has been designed for sportives and all day escapades, where you want to rack up the miles, in comfort and at speed.

This balance between performance and all-day comfort stems from Cannondale's S.E.R.G. geometry, which offers an engaging and smooth ride. Offering a balance between an all out race position and a more upright position.

The innovative, SAVE PLUS micro-suspension technology, used in the rear triangle and fork, provides a smooth and comfortable ride, absorbing road buzz.

The Shimano 105 5800, 11-speed groupset brings smooth and ever-reliable shifting to the table and pairs with the FSA BB30A bottom bracket. FSA have also added their Gossamer Pro crankset that uses a 50 outer and 34 inner compact chainring for strength and numerous gearing possibilities.


  • S.E.R.G. Synapse Endurance Race Geometry: With its slightly taller head tube, slightly longer wheelbase and slightly slacker head angle, S.E.R.G. strikes the ideal balance between pure race positioning and upright comfort. Perfect for long days in the saddle and confident handling on all road surfaces.

  • Save Plus Micro-Suspension System: The Save Plus Micro-suspension system is a three part system, comprised of the carbon lay-up, the rear triangle and fork, and the seat post and seat tube, all designed to collaborate seamlessly to reduce vibration, improve handling, and increase comfort.

  • Save Plus Micro-Suspension System (Seatpost and Seat Tube): The elegantly scalloped seat tube and the smaller diameter 25.4mm seatpost are designed to flex together to provide more comfort when seated. The integrated collarless seat clamp allows more of the seatpost to flex than with a traditional clamp.

  • Save Plus Micro-Suspension System (Rear Triangle and Fork): The frame and fork’s carbon layup is designed to optimise high-frequency vibration dissipation, reducing road buzz. The radical helixed shapes of the chain stays and seat stays work in conjunction with the offset dropout fork to allow the wheels to track over imperfections in the road for better handling and control, seated or standing.

  • Power Pyramid/BB30A: The seat tube splits asymmetrically to meet a new wider BB30A bottom bracket, for maximum stiffness with minimal weight.

  • Ballistec Carbon Construction: Extreme light weight. Perfectly tuned stiffness. Remarkable strength.

  • SM = Standard Mod carbon for strength and responsiveness.
