Why Choose the Cannondale Synapse 105?
The Cannondale Synapse series has been a benchmark in the endurance road bike category since its introduction in 2006. The Cannondale Synapse 105 model brings premium features to a more accessible price point, making it ideal for riders who want pro-level performance on real-world roads.

Recent updates, including the 2025 redesign, have made the Synapse even more capable. It now features increased compliance (up to 20% more than previous generations), wider tire options, and integrated storage solutions like the StashPort for tools and essentials. Riders praise its ability to handle rough pavement, light gravel, and epic climbs while maintaining a lively, responsive feel.
Key Features and Specifications of the Cannondale Synapse 105
The Cannondale Synapse 105 is built around Cannondale’s renowned SAVE micro-suspension technology, which uses strategic flex zones in the frame, fork, and seatpost to absorb road buzz without adding weight or reducing efficiency.
- Frame and Fork: Lightweight BallisTec or Synapse Carbon construction with full carbon fork. Asymmetric design enhances stiffness for disc brakes, and size-specific tubing ensures consistent ride quality across all frames.
- Groupset: Full Shimano 105 11-speed or 12-speed (in newer models) with hydraulic disc brakes for precise shifting and powerful stopping in all conditions.
- Drivetrain: Compact 50/34T chainrings paired with an 11-34T cassette, providing a wide gear range for steep climbs and fast descents.
- Wheels and Tires: Durable alloy rims (like RD 2.0 or DT Swiss) with Vittoria Zaffiro or Rubino Pro tires in 28-32mm widths. Clearance for up to 35mm+ tires in recent models adds versatility for mixed terrain.
- Geometry: Relaxed endurance positioning with a taller head tube for an upright ride, stable handling, and confident descending.
- Additional Perks: Hidden fender mounts, rack compatibility, and options for integrated lights/radar in higher trims.
Weight typically hovers around 9-10kg, making it competitive in the endurance segment.
Ride Quality: Comfort Meets Speed
What sets the Cannondale Synapse 105 apart is its perfect balance of comfort and performance. The SAVE system effectively smooths out rough roads, reducing fatigue on long rides. Reviewers often describe it as “sprightly yet forgiving,” with nimble handling that feels race-inspired but without the aggressive posture of pure race bikes like the Cannondale SuperSix EVO.
Descending is a highlight – stable and confident, even on twisty roads. Climbing is efficient thanks to the stiff frame and wide gearing. Many riders report completing centuries or multi-day tours with minimal discomfort, crediting the upright geometry and compliant frame.
Compared to competitors like the Trek Domane or Specialized Roubaix, the Synapse offers a slightly racier feel while still prioritizing all-day comfort.
