So Smooth
With Synapse Alloy, comfort is built in. Synapse Alloy’s frame tubes are shaped and butted with absolute precision to help absorb road chatter and bumps without adding weight or isolating you from the ride experience.
So Comfortable
Synapse Alloy moves with both pace and grace. A comfortable riding position, planted handling, and the wonderful responsiveness of alloy under power, all create a bike that will help you feel in control and get more out of every ride.
So Capable
Synapse’s comfort and confidence brings utility, too. Balanced geometry, plenty of gear/bottle mounts, and clearance for 32mm wide tires that bring cushion and grip, mean Synapse is ready to rock on any road.
So Ready
Don’t sweat the small stuff. Synapse comes with a Contain top tube bag on some models. It’s easy to load and easy to reach while you’re riding. Bring snacks, tools, a map, or whatever else will help you go farther.
Features
Specially Smooth
Comfort and control you feel, not see. Everything you need for a bump-absorbing ride is engineered into the frame’s tube shapes and alloy construction – giving you a light, smooth, and sleek ride you have to feel to believe.
Mount Up
Mounts and eyelets galore on Synapse Alloy means you can gear up for whatever the day, week, or month has in store. Your favorite bottle cages, gear bags, and accessories are good to go.
SmartSense Compatible
Make every ride better with enhanced visibility and awareness. The SmartSense-compatible Synapse Alloy frame means it’s easy to upgrade to our system of intelligent running lights and rear-facing radar.
Contain Toptube Bag
Easy to load, easy to reach. A Contain Toptube Bag is included, mounted just behind the headtube, so you can have what you need, right when you need it.
Trainer-Ready
Synapse Alloy will help you push hard, on or off the road. Synapse comes with easy-to-install end caps, making it quick and simple to mount the bike on a trainer.
Connected
An integrated wheel sensor delivers hyper-accurate speed, route and distance info while you ride, registers your bike, reminds you of needed service and more, all through the free Cannondale App.
