Road Reimagined

Go long, go short, go fast. This is WorldTour performance for real world rides.

Model Description

Wireless brains meet all-road brawn. Synapse Carbon 4 runs Shimano 105 Di2 for a shifting experience that feels straight off the pro tour, minus the bank loan. The frame delivers that signature Synapse ride—quietly fast, endlessly composed—and plays nice with wide tires, fenders, and long days. Call it the sweet spot between Sunday speed and weekday practicality.

What it's for

Comfortable high-performance road riding, long distance missions, fast group rides

Highlights

  • Lightweight, smoothly compliant, sleekly aero Synapse carbon frameset with StashPort downtube storage
  • Shimano 105 Di2 – Impressively smooth shifting from Shimano's journeyman electronic 2x12-speed drivetrain
  • DT Swiss 470 rims with Vittoria Rubino Pro IV 32c tires - grip, durability, and speed
  • Cannondale C1 Aero 27 Carbon seatpost - speed meets comfort

Road Reimagined


Real World Performance

Designed to go fast, built to go long, and made to keep you comfortable, the LAB71 Synapse takes all-around road performance to the next level. With a sub-1000-gram Hi-MOD frame, featuring wind tunnel-sculpted aero tubing, exceptional stiffness-to-weight, and a silky ride, it’s a bike that’s ready for anything you demand of it. Proven by Lachlan Morton on his record-smashing lap of Australia, Unreal speed, engineered for real-world roads.


Ride Confident

More visibility, more awareness, more integration, with our next-gen SmartSense system. All running from a single concealed battery. Intelligent lights adapt to let other road users know you’re there. While the rear-facing Garmin radar keeps you switched on to approaching traffic. Letting you ride the bike that’s up for anything, whatever time of day or night.

Compliant Comfort

With advancements in our carbon layup, our engineers have made the new Synapse 20% more compliant than its already butter-smooth predecessor, ensuring you feel 100% more comfortable even on the roughest roads.

Like A Glove

A great fit and feel makes for a great ride. And with our Proportional Response Construction, every rider gets that as standard. From the carbon layup through to the geometry, everything on Synapse has been tuned and tested by frame size. So that your bike works in harmony with you to give the best possible ride for you and your height.

Bring it all, bring it on

Our all-new StashPort storage system in the downtube is there when you need it and hidden when you don’t. Paired with its StashBag buddy, you can bring along your ride essentials and know that they’ll be secure, whatever you get up to out there. Meanwhile, best-in-class tire clearance lets you take the idea of riding for longer to a whole new level.

 

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.
