In the world of cycling, finding a bike that balances performance, comfort, and affordability can feel like a challenge. Enter the Cannondale Synapse 105, a standout model in the endurance road bike category that’s designed for riders who crave long-distance adventures without sacrificing speed or handling. Whether you’re a seasoned cyclist tackling century rides or a beginner looking to upgrade your setup, the Cannondale Synapse 105 offers a compelling mix of innovative engineering and reliable components. In this comprehensive blog post, we’ll dive deep into what makes this bike special, exploring its features, specifications, ride quality, and more to help you decide if it’s the right choice for your cycling journey.
A Brief History of the Cannondale Synapse Lineup
Cannondale has long been a pioneer in the bicycle industry, known for pushing boundaries with aluminum and carbon fiber frames since the 1980s. The Synapse series, introduced in the early 2000s, was created to address the needs of endurance riders—those who prioritize comfort over aggressive racing geometries. The Cannondale Synapse 105 builds on this legacy, incorporating modern updates like disc brakes and wider tire clearance while staying true to the brand’s commitment to lightweight, responsive designs.
Over the years, the Synapse has evolved. Early models focused on vibration-damping technologies, and recent iterations, including the Cannondale Synapse 105, have integrated features like hidden fender mounts and internal cable routing for a cleaner, more aerodynamic look. This bike isn’t just about nostalgia; it’s a forward-thinking machine that’s perfect for today’s mixed-surface roads, where pavement meets light gravel.
Design and Frame Technology in the Cannondale Synapse 105
At the heart of the Cannondale Synapse 105 is its SmartForm C2 Alloy frame, a proprietary aluminum construction that’s both lightweight and durable. Weighing in at around 1,100 grams for the frame alone (depending on size), it strikes an impressive balance between stiffness for efficient power transfer and compliance for all-day comfort. Cannondale’s SAVE (Synapse Active Vibration Elimination) technology is woven into the frame, with strategically placed flex zones in the rear triangle and seatstays that absorb road buzz without compromising pedaling efficiency.
The full carbon fork complements the alloy frame, providing precise steering and additional vibration damping. This combination makes the Cannondale Synapse 105 feel lively on climbs and stable on descents. Geometry-wise, it’s endurance-oriented: a slightly taller head tube promotes an upright riding position, reducing strain on your back and neck during long rides. Stack-to-reach ratios are optimized for comfort, with sizes ranging from 48cm to 61cm to fit a wide array of riders.
One of the standout design elements is the bike’s versatility. With clearance for up to 32mm tires (and even wider in some setups), the Cannondale Synapse 105 can handle rough roads or light gravel paths, making it ideal for adventure cycling. Internal routing keeps cables out of sight, enhancing aesthetics and reducing maintenance hassles. Available in colors like Midnight Blue or Graphite, it looks as good as it performs.
Key Components and Specifications
Let’s break down the specs that define the Cannondale Synapse 105. This model comes equipped with a full Shimano 105 groupset, which is renowned for its reliability and smooth shifting. The 11-speed drivetrain features a compact 50/34t crankset paired with an 11-34t cassette, offering a wide gear range for tackling steep hills and fast flats alike.
Braking is handled by Shimano 105 hydraulic disc brakes with 160mm rotors front and rear, providing confident stopping power in all weather conditions. This is a game-changer for endurance riding, where wet descents can turn sketchy without reliable modulation.
Wheels are Cannondale’s own RD 2.0 rims, laced to Formula hubs with 28 spokes for durability. They come wrapped in Vittoria Zaffiro Pro Slick tires in 700x30c, which roll efficiently on pavement while offering enough grip for occasional off-road excursions. The cockpit includes a Cannondale 3 alloy handlebar (38-44cm widths depending on frame size) and a matching stem, topped with comfortable bar tape.
Other notable specs include:
- Saddle: Fabric Scoop Shallow Sport, a well-padded option for long rides.
- Seatpost: Cannondale 3 alloy, 27.2mm diameter, with a micro-adjust clamp.
- Weight: Approximately 9.5-10kg (21-22 lbs) fully built, varying by size.
- Price: Typically around $1,800-$2,000, though deals can bring it lower.
These components make the Cannondale Synapse 105 a mid-range powerhouse, punching above its weight in terms of value.
Ride Experience: How the Cannondale Synapse 105 Performs on the Road
Riding the Cannondale Synapse 105 is an experience that blends excitement with endurance. From the first pedal stroke, you’ll notice the frame’s responsiveness—the alloy construction transfers power efficiently, making accelerations feel snappy. On smooth tarmac, it glides effortlessly, and the SAVE technology shines on rougher surfaces, smoothing out potholes and chip-seal vibrations that would fatigue you on a stiffer race bike.
Handling is predictable and confidence-inspiring. The endurance geometry encourages a relaxed posture, perfect for hours in the saddle. During a test ride on rolling hills, the Cannondale Synapse 105 climbed with ease, thanks to the wide-range cassette, and descended stably, with the disc brakes offering precise control. It’s not the lightest bike out there, but the weight is well-distributed, making it feel agile rather than sluggish.
For mixed-terrain enthusiasts, the tire clearance allows swaps to gravel-oriented rubber, expanding its capabilities. Riders report averaging higher speeds on long outings due to reduced fatigue, and the bike’s stability at high speeds (up to 40+ mph on descents) is noteworthy. If you’re into group rides or solo explorations, the Cannondale Synapse 105 adapts seamlessly.
Pros and Cons of the Cannondale Synapse 105

Comparing the Cannondale Synapse 105 to Competitors
How does the Cannondale Synapse 105 stack up against similar bikes? Let’s compare it to a few popular options.
- Trek Domane AL 5: Similar alloy frame and Shimano 105 setup, but the Domane emphasizes IsoSpeed decouplers for vibration damping. The Cannondale Synapse 105 edges it out in tire clearance and overall lightness.
- Specialized Roubaix Sport: A carbon bike at a higher price, offering Future Shock suspension for superior comfort. However, the Cannondale Synapse 105 provides better value for budget-conscious riders.
- Giant Defy Advanced 3: Carbon frame with similar endurance focus. The Synapse’s alloy build makes it more affordable, though the Defy might feel plusher on rough roads.
In reviews, the Cannondale Synapse 105 often scores high for its balanced ride, making it a top pick for entry-to-mid-level endurance cyclists.
Who Should Buy the Cannondale Synapse 105?
This bike is perfect for:
- Beginners stepping up from entry-level models.

If you’re a pure racer, you might prefer something more aggressive like Cannondale’s SuperSix. But for most, the Cannondale Synapse 105 delivers versatility without compromise.
Maintenance and Upgrades for Longevity
To keep your Cannondale Synapse 105 in top shape, regular maintenance is key. Clean the drivetrain after wet rides, check tire pressure weekly (around 80-100 PSI for 30c tires), and service the hydraulic brakes annually. Upgrades like carbon wheels or a power meter can elevate performance, but the stock setup is solid for years of use.
