Cannondale Synapse 105 Disc Road Bike 2021
An endurance themed geometry and a responsive but comfortable alloy frame are blended with reliable components to make the Cannondale Synapse 105 Disc Road Bike an ideal partner for tackling the most challenging of sportives and training rides.
The reactive alloy frame teams up with a stiff carbon fork to promote a ride experience that’s packed with acceleration and efficiency. Both of these components are tuned via Cannondale’s SAVE micro-suspension technology that works to smooth the biggest bumps in the road and eliminate vibrations for a more comfortable, less fatiguing ride. Clearance for up to 32mm tyres allows the use of plush, cushioned rubber for more control across irregular road surfaces. The endurance inspired geometry utilised in the frameset is ideal for preserving energy over the longest of days in the saddle but also facilitates effective power transfer for when surging up steep climbs.
Reliability and strength are at the heart of the RD 2.0 alloy wheelset, but it is also light for nimble handling and frequent changes of pace. Any topography can be conquered thanks to the broad range of gears provided by the Shimano 105 setup that glides across its sprockets with accuracy. The disc brakes are powerful and precise, even under the teeming rain and grant confidence to experienced and beginner riders alike.
Smart and discreet mudguard mounting points on the frame and fork give the rider the option of increased shielding from cold road spray facilitating rinding throughout the harsh winter months.
