Cannondale Synapse Neo All Road 2 2025

All Roads Are Yours

With a powerful electric drive unit and features for comfort, durability, and practicality, all roads are yours on Synapse Neo Allroad. Made for the road ahead – no matter what that road's made of. The Synapse Neo Allroad 2 gravel bike is made with a light, durable carbon frameset, an ultra-reliable Shimano GRX drivetrain, a Bosch Performance Line SX e-motor, and tough, grippy 40mm tires, so you can roll with confidence over any road, anywhere. It’s practical, too, with mounts for fenders, a rear rack, and even a kickstand. Exploring the backroads with speed and comfort, spirited gravel rides, taking the road less travelled.

Rock Steady
Synapse Neo Allroad keeps things reliable, so you can keep the ride rolling. The quiet Bosch Performance Line SX drive unit is neatly integrated into the carbon frame, and premium componentry like the Conceal Stem, a flared-drop handlebar, and sharp shifting keep things clean, comfortable, and simple.

Ready for Epic
Whether you’re planning for a bike-packing trip, an epic day out, or just some foul weather, Synapse Neo Allroad comes with multiple mounts for fenders, a rear rack, and even a kickstand.

Your Comfort Zone
The carbon fiber frameset features special areas designed to allow small amounts of flex for bump and vibration absorption, creating a super comfortable ride. The riding position is perfectly balanced, too: upright enough for comfort and control in the rough, but still low enough for poise and efficiency at speed.

Masterful Material
Based on the non-electric Synapse endurance race bike and rendered in the refined Series 2 carbon fiber construction, the Synapse Neo frameset achieves low weight and superlative performance.

Easy Interafce
The Bosch Kiox 300 display on the handlebar is easy to read and use, giving you full control over the drive system, and can even work in conjunction with the Bosch Flow app for more convenience.

Go hard, stop easy
Huge descents, high speeds, wet weather: the powerful hydraulic disc brakes can handle it all and bring you to a stop with cool, confident control.

The right rubber
The Vittoria Terrano Dry, 38c, tubeless-ready tires are tough but smooth, grippy but fast. They can get you where you want to go and back again with confidence, and you can put up to 45mm-wide tires on if you’d like.

Full-Throttle Throne
The Fizik Terra saddle brings epic comfort to epic rides. Designed to be supportive on bumpy and technical terrain, it hits the sweet spot for riders that want to go anywhere the day may take them.

Go With the Flow
The light but mighty Bosch Performance Line SX drive unit provides support up to higher cadences for a natural pedaling feel. Powered by a 400Wh battery, it brings a powerful boost up to 25km/h, then seamlessly disengages for effortless pedaling at greater speeds.

Versatility built in
Every Synapse Neo Allroad comes with mounts for fenders, a kickstand, and a rear rack, making it easy to set the bike up for poor weather and greater utility.

Fits like a glove
The Proportional Response approach means that every Synapse Neo Allroad is engineered for consistent performance across the size range. From the biggest to the smallest, every rider gets the same ride quality, handling, and responsiveness.

Ready to roam
When you don't want the ride to end, it doesn’t have to. An optional secondary battery can be installed in minutes and adds 250Wh. That means going farther and pushing higher, while still getting home easily.
