Synapse LAB71 SmartSense Road Bike

Cannondale Synapse LAB71 SmartSense Road Bike

Two decades ago, the original Synapse reshaped road cycling by offering a fresh alternative to both aggressive race bikes and relaxed comfort models. It combined race-level performance and weight with genuine rider-friendly comfort and handling, effectively launching the Endurance road bike category.

Now in its sixth generation, the latest Synapse LAB71 Road Bike continues to lead, redefining road performance with a sub-1000-gram carbon frame, wind-tunnel-optimised tube shapes, and class-leading stiffness-to-weight.

Designed for speed, distance, and comfort, it features 20% more compliance than its predecessor for a smoother ride, Proportional Response Construction for size-specific tuning, and thoughtful details like the StashPort downtube storage system, hidden top tube bag mounts, and room for high-volume tyres. Trusted by riders like Lachlan Morton for epic challenges, the Synapse delivers unreal performance for real-world roads.

Innovative Frame Design
The Cannondale Synapse features a refined Hi-MOD carbon layup that reduces frame weight by over 100 grams while maintaining the stiffness, ride quality, and durability the Synapse is known for. Each frame size benefits from size-specific construction, ensuring an optimal balance of stiffness and compliance across the range.

A D-shaped seatpost improves aerodynamic efficiency and enhances vertical compliance, helping to reduce rider fatigue on long days in the saddle. Cannondale’s proprietary V-shaped Delta Steerer allows for fully internal cable routing while reducing the frontal area of the head tube for improved aerodynamic performance.

With generous tyre clearance allowing up to 48 mm at the front and 42 mm at the rear, the Synapse is built to handle a wide variety of road surfaces, making it ideal for long-distance and mixed-terrain riding.

SmartSense Gen 2.0
The second generation of Cannondale’s intelligent light and radar system is more advanced than ever. The redesigned headlight is smaller yet significantly brighter, delivering up to 800 lumens (400 lumens in STVZO-compliant regions). A compact radar and taillight unit is neatly integrated beneath the saddle, while the upgraded battery, now fully housed in the downtube offers more than double the capacity of the previous version, providing up to 24 hours of run time.

Storage Solutions
The integrated StashPort storage system sits discreetly beneath the downtube bottle cage, offering practical space for tools, nutrition, and essentials via the included StashBag.

Wheel Sensor
A Cannondale Wheel Sensor provides accurate data on speed, distance, and route tracking, while also offering maintenance reminders and more through the Cannondale App.
