For riders who enjoy nothing more than long days in the saddle, pushing the limits of their performance, Cannondale have created the Synapse Carbon 105 Disc Road Bike.

The BallisTec carbon fibre frameset provides an excellent mix of stiffness for acceleration, and low weight for uphill speed; and with SAVE micro-suspension technology, you can ride further in comfort. The Shimano 105 groupset shifts with accuracy and reliability while the hydraulic disc brakes offer modulated stopping power that's consistent in any weather. Cannondale's own Si cranks are made to suit the bottom bracket perfectly, delivering more of your power to the rear wheel.

Cannondale Synapse Carbon 105 Disc Road Bike 2019

The Cannondale Synapse Carbon 105 Disc is the perfect road bike for riders who want a fast endurance option. The superb frameset is specced with componentry that delivers great performance without breaking the bank.

The frame and fork are built with Cannondale's BallisTec carbon fibre layup, a seriously lightweight material that boasts stiffness in the right places to deliver an exciting and responsive ride. Acceleration is quick, and climbing is made easy due to the low overall weight of the bike. SAVE micro-suspension technology keeps road buzz to a minimum, keeping the rider fresher for longer and making those epic rides all the more enjoyable.

Unmatched stopping power is provided by Shimano's 105 hydraulic disc brakes, which perform consistently in any weather. The 2x11-speed 105 shifters and derailleurs offer the performance of Shimano's top-end components but at a more accessible price point.

Cannondale has opted to supply their own HollowGram Si crankset which utilises the BB30 bottom bracket standard for improved power transfer. With compact 50/34t FSA chainrings feeding the chain through an 11-34t cassette, you have a wide range of gears suitable for the steepest climbs as well as riding at pace on the flat.

A set of reliable wheels round off the specification, with 28mm Zaffiro tyres from Vittoria providing plenty of comfort on the road. With hidden mounts for mudguards, this is truly a four-season endurance bike that can see you riding in comfort for hours on end.
