We’ve had the Cannondale SuperSix Evo 4 demo bike in the shop for a while now. Aside from a few “sanity check” spins to bed in brakes on new builds, I hadn’t really opened it up. But even in those parking lot sprints, the bike felt incredibly “connected.” You know that feeling where your leg feels like a literal extension of the crank? No lag, no flex, just pure power transfer. That’s the Evo 4.

I had high expectations, but life kept getting in the way of a proper shakedown. Between a bout of overtraining and a pesky toe cut that had me limping through my runs, my “engine” was feeling a bit battered.

The Eidi Surprise

By Saturday, I needed some “bike therapy.” I walked into the store the day before and saw Hikmath rebuilding the SuperSix frame. I jokingly asked if I’d get my “Eidi” (the traditional Eid gift) before he broke his fast on the final day of Ramzan. He just smiled and said, “It’ll be ready.”

I rushed home, grabbed the car to ferry the bike back, and sure enough, Hikmath delivered. While the bike was pristine, my legs were trashed. A long soak in Epsom salts and a desperate session with the massage gun were my only hopes of doing this beauty justice.

Chaos at the Start Line

The next morning, I rolled up to a 25-rider group. Our “Pied Piper,” Krish, had brought his entire crew along. In classic fashion, I took a “shortcut” that resulted in me arriving exactly on time—which, in cyclist speak, means I was 10 minutes late. I took my fair share of grief from Om and Pondi.

It was hilarious when I tried to pair my heart rate monitor to the new Magene C606 V2. It detected about 10 different HRMs in the vicinity. Since I didn’t know remember sensor’s ID, I just picked one. For all I know, I spent the ride monitoring Pondi’s stress levels instead of my own.

The Ride: Geometry and Gearing

The plan was a 30km “easy” spin to the TT segment. I spent this time getting acquainted with the fit. At a size 54, the bike felt like home. While it’s the same geometry as the Lab71 version used by the EF Education pro team, it’s surprisingly accessible. You don’t need the flexibility of a gymnast to feel comfortable in the cockpit.

The Build Specs:

  • Groupset: Shimano 105 12-speed (crisp and reliable).
  • Wheels: DT Swiss R460DB alloy rims with Shimano hubs.
  • Tires: Vittoria Zaffiro Pro Slick (700x25c).

Usually, putting stock alloy wheels on a high-end carbon frame creates a weird weight imbalance, but this felt remarkably poised. Even on 25c tires—which felt like a throwback since I usually run wider—the vibration damping was impressive.

Dropping the Hammer

Once we hit the TT segment, the “easy ride” protocol vanished. I tucked into the drops of the 400mm wide Vision Trimax bars. They have a shallow, comfortable drop, though I wouldn’t mind a narrower 380mm setup for extra aero gains.

Then, I heard it: the unmistakable whoosh of an aero train.

Pondi (on a full Tri-rig) and Aditya launched. I dug deep to hitch a ride. We were flying until we hit the village crossroads—the site of a nasty crash a few months back. A bus/car/cyclist “after you” moment cost us our momentum, and we lost our fourth rider, Praveen, who (understandably) took that section with a bit more caution.

Now it was down to three.

Pro Tip: If you want to annoy a guy on a Tri-bike doing all the work, ask him why he has 12 gears if he’s only using the top three.

Pondi didn’t find it as funny as I did. He attacked immediately. The “banter” stopped as we all started tasting blood. We traded pulls, survived a rogue truck blocking the road, and eventually, Pondi gapped us to claim the KOM. Strava ride link for TT segment. (One of the power pedals was out of charge so power numbers are off)

The Look: Form Meets Function

The design of the Evo 4 is a masterclass in modern aero-styling. Those dropped seat stays and the razor-thin seat tube aren’t just for comfort—they make the frame look incredibly fast even when it’s leaning against a cafe wall.

The sculpted headtube flows seamlessly into a wide-stance fork that managed to tick both my “looks cool” and “aero efficiency” boxes simultaneously. It’s available in two distinct personalities: a stealthy, subdued Black for the purists, and a brilliant Orange for those who want to be seen from space. Personally? I’m a sucker for the Orange—it just looks like it’s ready to ignite.

Weight

The demo bike weighs 8.6kg without pedals and bottle cages.

Other notes

The frame comes with the custom aero bottle cages and bottles which is a nice touch. Needs to be bought separately if you take the complete bike.

We can use any regular stem, but the specific stem offers a cleaner look.

Saddle is a Prologo Nago RS STN – does its job. Didnt notice any issues with it. However I personally prefer saddles where the top surface is flat rather than being rounded.

The bike comes with a Cannondale Wheel Sensor which is a speed sensor. When connected with Cannondale’s app it can give service alerts.

Final Verdict

Even with overtrained legs and an aging system, the SuperSix Evo 4 made me feel fast. Whether I was tucked into “imaginary aero bars” or attacking a kicker, the bike was responsive and surgical in the corners.

I’ve owned a Cannondale Quick and a CAAD in the past—bikes that built my love for the sport. The CAAD was my first road bike. We still have a vintage Cannondale Crit 3.0 from 1990 at the store. This is a super stiff Aluminium bike made for crit racing. The Supersix Evo 4 carries the DNA with the modern touches. Aero, not too heavy even with an alloy wheelset and super stiff while not being uncomfortable. Krish who also loved the bike did feel that it was a bit stiff and transferred more vibrations. I guess that my experience with a steel road bike which has 25c tyres made me immune to it.  The Supersix Evo4 is a bit pricier than a Merida Reacto or the new Gusto Duro Evo, but the balance and “soul” of the ride are hard to beat.

You don’t need to be able to touch your toes to ride a world-class aero bike. You just need the right Eidi.

Know Your Carbon: The Cannondale Hierarchy

Fun fact for the spec-chasers out there: Cannondale actually offers three distinct flavors of carbon layup for the SuperSix Evo. It’s like picking your level of “spice”:

  • Carbon: The entry-level layup I rode today. Stiff, reliable, and punches way above its weight class.
  • Hi-Mod Carbon: The mid-level “goldilocks” frame—shaving off grams while adding extra stiffness.
  • Lab71: The “Ultra” tier. This is the pro-level layup used by the EF Education team. I’ve had a go on one of these, and honestly? It feels like there’s a hidden motor in the bottom bracket. It’s so fast it almost feels illegal. 🤫

One Last Tip for the Road

The demo bike came stock with a 50/34 105 Crank (170mm arms). While that’s great for spinning up steep kickers, this frame begs to be pushed harder on the flats. If you’re looking to truly unlock the speed this bike is capable of, I’d highly recommend swapping to 52/36 chainrings. Your quads might complain at first, but your Strava segments will thank you.
