Zwift’s latest update includes a new gravel frame from Cannondale, the company’s first gravel frame in game. Named the “Cannondale SuperX Lab71”, the frame in this colorway is currently only available as a standalone frameset from Cannondale:
On Zwift, you’ll need to be updated to game version 1.110+ to see this bike in the Drop Shop. You’ll also need to be at level 28+ with 1,000,000 Drops to buy it. Here’s how it’s described in the Drop Shop:
“Made to absolutely smash gravel races. Simple as that. This is full-gas road race performance engineered for the full thrash world of gravel. Elbows out, head down, get off the front and don’t look back. SuperX only has one destination – the top step.”

It’s rated 2 stars for aero, 3 stars for weight, and before this week’s update, only one gravel bike (the Cervelo Aspero) had such high ratings. One would expect this bike to perform well against existing in-game gravel bikes, but since Zwift’s 4-star system isn’t the most granular of performance measurements, we ran this frame through our precise tests to measure performance at nerd-level detail. Let’s dive in!
Note: test results below are from a 75kg, 183cm rider holding 300W steady using Zwift’s stock gravel wheelset on the un-upgraded version of the frame.
Aero (Flat/Rolling) Performance
Cannondale’s SuperX Lab71 turns in a strong performance on the flats, beating all existing gravel bikes on tarmac. It’s even a bit faster than the new Canyon Grail SLX which was also released this week!
For comparison, the stock Zwift Gravel frame loses 145.4 seconds to our baseline Zwift Carbon frame across an hour of flat tarmac, while the (former) fastest gravel bike, the Cervelo Aspero, loses 115.2 seconds. The SuperX Lab71 only loses 112.4 seconds.
Climb Performance
The Cannondale SuperX Lab71 is a strong climber compared to the game’s older gravel frames, and also beats the new Canyon Grail SLX.
The stock Zwift Gravel frame loses 161.8 seconds to our baseline Zwift Carbon frame across an hour of Alpe du Zwift climbing, while the (former) fastest climbing gravel bike, the Specialized Crux, loses 122 seconds. The SuperX Lab71 only loses 118.7 seconds.
Jungle (Dirt) Performance
Of course, nobody really cares about how well a gravel frame performs on pavement, which is where we do our aero and climb testing (above). While those flat and climb tests help us tease out a frame’s aerodynamic capabilities and weight, when it comes to gravel bikes, people really want to know how fast they are on Zwift’s virtual dirt!
In that regard, the SuperX Lab71 performs quite nicely.
In fact, the Cannondale SuperX Lab71 is the new “king of the jungle” in our tests, putting 5.2 seconds into the previous leader, the Cervelo Aspero, across 1 hour of Jungle Circuit riding.
Upgrading Your Cannondale SuperX Lab71
Like all frames in Zwift, Cannondale’s SuperX Lab71 can be upgraded in five stages. As a high-end race bike, each of the five stages results in a performance improvement. The SuperX Lab71 upgrade stages are as follows:
- Ride 200km, pay 100,000 Drops for an aero upgrade
- Ride 260km, pay 200,000 Drops for a weight reduction
- Ride 320km, pay 350,000 Drops for a drivetrain efficiency improvement
- Ride 380km, pay 500,000 Drops for an aero upgrade
- Ride 440km, pay 750,000 Drops for a weight reduction
You can expect a fully-upgraded Cannondale SuperX Lab71 to be approximately 28 seconds faster on a flat hour and 36 seconds faster on an hour-long climb vs the “stock” Cannondale SuperX Lab71.
Conclusions
Cannondale’s SuperX Lab71 beats every other gravel bike in Zwift, making it the new go-to frame for races involving a significant amount of dirt.
Where gravel riders formerly had to choose between the Cervelo Aspero (more aero) and the Specialized Crux (lighter weight), the SuperX Lab71 is king on flats and climbs, making the choice an easy one.
Should you rush to the Drop Shop and buy the SuperX today? Maybe. I might do it myself, because it looks pretty sweet. But with rumors of fresh dirt roads coming to Zwift, my guess is we’ll see more gravel frames and wheels added to the game shortly. So it may make sense to wait, if you don’t have a key gravel race coming up.
We’ll be adding this bike to the following posts soon:
