Big Ride Rubber
Best-in-class clearance for tires with a maximum measured width of up to 48mm in the front and 42mm in the rear - with at least 4mm of extra clearance on each side - makes Synapse a true, ride-longer, ride-whatever kind of road bike.

More, from less.
The LAB71 and Synapse 1 get a refined, performance-boosting, Hi-MOD carbon layup that shaves over 100 grams off the frame weight, while maintaining Synapse's stiffness, ride-feel, durability, and lifetime warranty.

Proportional Response
Tuned for the rider, our size-specific construction creates optimal stiffness and compliance for each and every frame size in the Synapse range.

StashPort + StashBag
StashPort is our downtube storage system, accessed beneath the water bottle cage. StashPort holds tools, snacks, and other ride essentials in the specially designed StashBag, and on SmartSense-equipped bikes, houses the system battery (which also provides a cool, glovebox-style light when StashPort cover is opened).

D-Lightful
The D-shaped design of Synapse’s seatpost enhances aerodynamics and boosts vertical compliance, reducing muscle fatigue so that you stay fresher on those longer days.

Fly Delta
The unique-to-Cannondale, V-shaped Delta Steerer keeps your cockpit tidy and cables routed internally, while reducing headtube frontal area for drag-reducing aero gains.
