Elite-race performance meets all-day comfort.

SAVE PLUS Full Carbon Fork

Offset dropouts allow the fork blades to have the vertical compliance of a shallow rake fork, without sacrificing the Synapses nimble, precise handling. Refined carbon lay-up and SAVE shaping further enhance the forks vertical compliance.

SAVE PLUS Rear Stay Micro-Suspension System

A directional carbon lay-up and exaggerated vibration-absorbing tube shapes give the SAVE PLUS chain stay/seat stay system 13% more vertical deflection than the previous version, while actually improving the frames lateral and torsional stiffness.

Performance Geometry

Compared with our Elite race geometry, the Synapse features a 2-2.5 cm taller head tube, slightly relaxed head angle and longer wheelbase for a more upright riding position and a stable yet lively feel. It's confidence-inspiring, relaxing and it avoids the sluggish feel and awkward handling of many road bikes.

              Comments about cannondale SYNAPSE CARBON 4 RIVAL:

              I purchased the Synapse because I'm planning to participate in the Seattle to Portland 200 mile ride next June. My old Columbus SLX bike was proving be very uncomfortable for long distance riding because it was so stiff and put me in a uncomfortable riding position.

              I test rode the Synapse Carbon 4 Rival and several other endurance type carbon bikes and found that it had just the right combination of compliance (comfort) and liveliness that I was looking for. I wasn't sure about the SRAM components since my old bike was equipped with Dura-Ace. However, after just a couple of rides I found that the SRAM Rival was easy to manage and shifted precisely. The Rival brakes are very good also. The 11-32 cog in the back allows for easy ascending steep grades with a minimum of effort.

              The riding position of the Synapse is very comfortable yet allows me to hammer effectively when I'm in the drops. I've ridden a couple of moderately long rides since I've gotten the bike, and I think the Synapse provides a near perfect combination of lightness, stiffness, comfort and liveliness.

              Altogether this is a really good melding of endurance bike geometry with several performance features to make it a superb all-around bike.

              I'm not sure about the saddle yet. The Prologo Kappa has been OK for now, but it may not comfortable for the six hour rides I'll be making as my training program proceeds. Also, I might be making a performance upgrade on the wheels in the future. But for now, I'm very happy that I chose the Synapse Carbon 4.

              I've ridden a couple of centuries in the past, and I'm sure this bike will get me to the finish line in fine shape.

                    My Cannondale Synapse Carbon 4 Rival was purchased in June 2013. It has been evaluated over 300 miles including long training rides in excess of 60-miles and a 40-mile Gran Fondo ride. My primary training bike remains a 2005 Cannondale Cyclocross. However, I plan to use my Synapse Carbon 4 Rival for once a week longest training rides, the local Gran Fondo, and other amateur cycling events.

                    The Rival components are smooth and work well with the light Synapse Carbon 4 frame. Getting a number of compliments, the stylish frame has a solid, high quality feel and is not at all flimsy. It absorbs harsh road vibration over uneven asphalt or concrete pavement. This makes for a comfortable ride, well-suited to long, paved trails. The gearing has the bike accelerating quickly and has very good long speed. In training rides thus far, the bike has consistently demonstrated quicker average speed over the usual courses.

                    With the 50/24 crank and available gear ratios, the bike is a great climber. During the Gran Fondo on June 29, it went up and over a number of rolling hills in West Michigan with little effort. I found the Synapse Carbon 4 Rival can hold its own matched against other brands. Coasting downhill on the Synapse Carbon 4 Rival's Mavic wheels and Schwalbe Durano tires, it passed other – in some cases more expensive - road bikes with surprising ease. The bike remained stable through cross winds and up to the MX attained throughout the event.

                    This is my first carbon-frame bike. At 5'-10" 155 lbs, I found the bike comfortable, great handling and fast over long distances with no problems to report with the saddle.

                    Simply put, the Cannondale Synapse Carbon 4 Rival is fun to ride. It really works as advertised.

                          I've had my Synapse 4 since January and have put about 1200 miles on it and I am still giddy with excitement. Boy am I hooked on the carbon frames! I moved up from a 2006 Trek Pilot 1.0 and Wow, what a difference. This bike is faster, handles better and is so much more comfortable! I was holding out for quite a while because I was convinced I had to have a triple crank to get my older(62) and bigger(195#)body up the hills. Boy was I wrong. The compact crank with the SRAM Rival 12-32 cassette gives me better gearing than my buddy gets on his Madone 4.5 with a triple crank. And the SAVE technology is a real plus on the longer rides I like to take.

                          If I could have given the bike 4.5 stars I would have. The only minor drawback would be the brakes. I plan to look into an upgrade to give me the ability to stop a little easier when I'm taking advantage of the bike's speed and need to stop suddenly. They're not bad; they could just be a little better.

                          I was so certain my first carbon frame would be a Trek but here I am with my Cannondale Synapse 4 and I couldn't be happier!

                          I really enjoy this bike. I used it about 3 months last fall until winter, then stored it until spring. I have maybe 500 miles on it. the SEAT had to be replaced. THOUGH IT LOOKED COOL. WAS HARD - I replaced it with a 175.00 "Italia Flight"

                          The TIRES also COOL LOOKING with the white lettering, LOVED the looks of those - but after a few months strings of fiber were shredding off the sidewalls. (often getting wrapped around the hub) I had around a dozen strings front and rear. My dealer said that's not normal and under warranty swapped with them new tires (today) Continental Ultra or something like that. I'm glad to get new tires, but REALLY DISAPPOINTED they don't look NEARLY AS COOL as the original tires. I really liked the white lettering. When you select a bike in part by how it looks and invest 3k with a couple extras... you'd like to keep it looking the way you bought it. Anyway before of these tires = (

                          Moved from a Scott Speedster. The synapse is a joy to ride. The jarring bumps of my previous aluminum and carbon bike are gone. The suspension is most notable. However the LOW END (though awesome looking) ProLogo seat is sub par for this bike. I hate replacing it because it looks so nice, but it's less than comfortable. I just ordered a Selle Itailia flight gel after trying the Prologo for 3 months and finding it's not going to improve.

                          Love the "raw" carbon look, However I'm new to this type of build and I find some of the finish "strange"? There are some swirls in some of the carbon (like the forks) and things like the top red line on the center bar is crooked. Though not painted, the color seems to be processed into the carbon? (this could be the norm for this process). I thought the swirls in the forks were flaws but my dealer said no that's normal. I think it's because it's a sort of composite? (like a chicken McNugget?)
                          At any rate it performs well once you look past the minor finish issues. (That really don't bother me). Gearing is just whatI need, While I find plenty of low end for the toughest hills, I tend to find it one gear short on the high end speed gearing. Meaning when going for strava speed records "downhill" I tend to fine myself wanting one more gear when up to speed. (35+ mph down hill). Though that need is rare... and I prefer having the low end gears for the tops of the steepest hills.

                          The one thing that worries me, at least for my size bike and setup. When the bars are turned max left or right the metal end caps on the bars align and smack the center carbon bar (quite squarely and hard). I fear in a crash one end of the bar may bust through the center bar. I would add some spacers on the head set, but then it's not really setup for me properly is it? I'd thought about adding some felt pads or something to the ends of the bars but who wants to trash it up with those? I'm not sure what to do about this problem. (one day I may be sorry I didn't do something about it when I find the center bar cracked in two?). Maybe I'm just paranoid.

                          This is the finest looking bike on the planet. I was so glad that when shopping with a 2500.00 budget, that the bike I liked the looks of the most was right on budget! Love all the graphics, wheels and tires. I do find it odd that the canondale logos are not on the sides and are off. This maybe due to the color process I mentioned above in the fit n finish comments. Maybe it's impossible to be precise, so better to have them "off enough to be intentional" rather than try to make them square on each side and find that the process makes them appear mistakingly crooked. Still minor issue. Comfort is key, while not compromising on performance. I'm 55, 5.7" and 145-150 lbs. I also love the grip tape, it's very padded. I have added aero bars, as well as a aerobar brake for safety in aero position. The one shame is the seat. While quality is really a issue with this bike, it seems dumb that Cannondale allowed this seat to be standard. But I'd rather upgrade a 20.00 saddle and shelve the 20 buck one than upgrading a 80-100.00 saddle. It's probably assumed that the saddle will need to be personalized to taste and rider. So the low end seat is probably the smartest choice, as it's expected to be upgraded. I really think this bike is 5 stars. But what to do when finish is a bit flawed and the seat is expected to be dumped. Ok, I'd give it 4.8 stars.
