20 years ago, the original Synapse did something pretty special – it quietly reimagined the whole road riding experience. Reasoning that most riders were really looking for something other than the high-strung, second-shaving pro race bikes, or the mild and mellow “comfort” road bikes available at the time, Synapse blazed a new path. By melding race-level performance and weight with real rider-friendly comfort and handling, Synapse set the template and the tone for what would become known as the Endurance road bike category. Fast forward two decades and six generations of Synapse, and it’s still out front, setting the pace and helping define what the future of core, for-the-love-of-the-ride, road bikes will look like. Synapse is real performance, for the real world.
Unreal performance for real world roads. Unless you’re a WorldTour pro, the Synapse is the perfect road bike for any job. Whether you’re tackling a record-breaking lap of Australia like Lachlan or smashing the not-so-social Sunday ride with your mates, the Synapse exceeds expectations. It blends WorldTour-level aerodynamics and stiffness-to weight with top-tier tire clearance, compliance, and smart features.
FEATURES:
- Real World Performance: Designed to go fast, built to go long, and made to keep you comfortable, the Synapse redefines road performance. With a sub-1000-gram lightweight carbon frame featuring wind-tunnel-sculpted tubing and PB-blasting stiffness-to-weight, it’s a bike that’s ready for anything you demand of it. Just ask Lachlan Morton why he trusted it for his record-smashing lap of Australia. Unreal speed, engineered for real-world roads.
- 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 deliver the best possible ride.
- Bring it All, Bring it On: Our all-new StashPort downtube storage system is there when you need it and out of sight when you don’t. Designed to work seamlessly with its StashBag companion, it keeps your ride essentials secure no matter where the road takes you. Plus, with hidden top tube bag mounts, discreet fender mounts, and room for high-volume, capable tires, the new Synapse is built to go long and go hard, no matter what the day brings.
-
Ride Confident: Enjoy improved visibility, enhanced situational awareness, and unmatched convenience with the second generation of our SmartSense system. More discreet, more integrated, and more powerful than ever, this intelligent and connected system of lights, radar, sensors, and our Cannondale app brings easy peace of mind to every ride. All running from a single concealed battery, the rear-facing Garmin radar keeps you switched on to approaching traffic, while intelligent headlights and taillights adapt blink patterns and/or brightness to let other road users know you’re there. It will even power your SRAM AXS shifting. And with just one long-lasting battery to charge, it’s
easier than ever to get out and ride with confidence.

Excellent adjustable drafting chair
Size: 934-Z, Color: Blue
Excellent chair design, extremely comfortable and exceptionally easy instructions to follow making for simple assembly. Love the amply wide cushioned seat and ergonomic backrest. The height adjustment feature works perfectly as well as positioning of the foot ring . Having the ability to raise the arms is also a big plus! I highly recommend this product for attractive appearance, comfort features, functionality and operation. Really nice chair!

Comfortable, stylish, and perfect for long work hours 💗✨
Size: 934-Z, Color: Pink
I bought this chair because I spend a lot of time working and needed something comfortable but also stylish, and I absolutely love it.
Since I started using it, I feel much better support in my back thanks to the lumbar support. It makes a big difference, especially during long work hours. The adjustable footrest is also a feature I didn’t know I needed, but now I use it all the time.
The flip-up armrests are very convenient because I can adjust them depending on what I’m doing or move them out of the way when needed.
The pink color is beautiful and adds a soft, elegant touch to my workspace. It looks great in a modern home office.
It feels sturdy, well-made, and very stable. Overall, it’s a great purchase that improved both my comfort and the look of my workspace.

All-around thumbs up!
Size: 934W-Z, Color: Black
So far, so awesome. Easy to assemble, comfortable, arrived quickly and is exactly what I was looking for. I have a tall work bench in my new studio so I needed a chair that we could allow me to sit higher than a regular office chair and allow me to get off my feet after standing on the concrete floor. Plus its a nice looking chair that I am sure will last a long time. I love the flip-up arms and the lumbar support. This is just right!

Perfect Balance of Comfort, Support, and Style!
Size: 934-Z, Color: Black, Size: 934-Z, Color: Black
I’ve been using this chair for a few weeks now, and I’m genuinely impressed with how much of a difference it’s made in my workspace. The mesh back is one of my favorite features—it offers excellent breathability and prevents that sticky, overheated feeling you sometimes get with solid-back chairs, even after sitting for hours. The seat cushion is firm enough to give proper support but still has enough give to keep me comfortable through long workdays. It feels like the perfect middle ground between soft and supportive.
The adjustable foot ring has been a complete game changer for me. I use a taller desk setup, and having somewhere to rest my feet makes a huge difference in posture and overall comfort. Whether I’m sitting upright for focused work or leaning back to read, it’s always at the right height.
The flip-up armrests are another smart design choice. When I’m typing, I like to have them down for support, but when I’m done, I can flip them up and push the chair neatly under my desk—saving space and keeping things tidy. The casters roll smoothly on both hardwood and rugs, so I can move around easily without scraping the floor or getting stuck. The overall build quality feels solid and sturdy, with no wobbles or creaks.
Assembly was surprisingly quick—everything was clearly labeled, the parts felt durable, and it only took me about 20 minutes from opening the box to sitting in the chair. The sleek, modern look is another big plus—it blends in perfectly with my home office décor without feeling bulky or taking up too much visual space.
If you’re looking for a chair that combines comfort, ergonomic support, durability, and style, I can’t recommend this one enough. It’s equally great for work, studying, or just relaxing at your desk, and it’s definitely been worth every penny.

OK for the price, but overall comfort is avergae
Size: 934-Z, Color: Mustard
Easy to put together, color (mustard) accurate to images, and while I understand this is not a high-end chair, I feel like it still needs to be rated for its quality.
Pros: the seat cushions are fairly comfortable and it rolls well. Adjustable footrest is easy enough and mostly sturdy.
Cons: For a tall office chair, it doesn't go up high enough. I actually had to lower my standing desk to sit at it, which then isn't where I want it when I'm standing now. It's also a bit wobbly. The seat area's attachment to the post isn't as solid as it should be for a tall chair, so while sitting, it does tend to lean/slope forward and wobble side to side. The lumbar support is not adjustable, so I'm not even really sure what it does. And the armrests are not very comfortable to use. Since they are hard plastic, they are just a bit too rigid to rely on for any comfort. They are basically there to hold on to when you're getting out of the chair.
