All About the New Shimano DURA-ACE C36 Wheels in Zwift

This week’s Zwift release includes a minor configuration fix for the new Shimano DURA-ACE C36 wheelset. The C36 wheels replace the C40 wheels in the Drop Shop, which means if you already own the C40 wheels they will remain in your garage, but once you update to Zwift version 1.101+, you will not be able to purchase the C40 wheels. Which should be fine with everyone, since the C36 is a better wheelset at a better price!

Here’s what the Drop Shop says about them: “With both a lighter, wider all-carbon rim and a lighter hub, the new DURA-ACE C36 won’t shy away from a day of climbing. The new rim is 36 mm deep and still delivers a good aerodynamic efficiency despite its gossamer weight. Meanwhile the hub features an alloy freehub body and new engagement mechanism for increased rigidity.”

The wheels are now available in the Drop Shop, accessible at level 6 and above, for the low price of 150,000 Drops. They are rated 3 stars for aero and 4 for weight, which is impressive given their price and low level requirement. Since Zwift’s 4-star rating system isn’t precise enough for our taste, we ran these wheels through our standard battery of tests to determine exactly how they perform in Zwift and stack up against other wheelsets in game.

Let’s dive in and learn all about the performance of this new wheelset from Shimano…

Aero (Flat/Rolling) Performance

Shimano’s DURA-ACE C36 wheels are on the lower end of aero performance in Zwift, although they are significantly faster than the D40 wheels they replace. While the D40 shows a 9.8-second gain over the baseline in a 1-hour flat ride, the C36 shows a 16-second gain.

As an affordable level 6 unlock, the C36 would be expected to perform in line with other lower-level unlocks. It squares up nicely against other low-level unlock wheels, performing better than all wheelsets at level 9 and below, except the Mavic Cosmic CXR60c which does very poorly on climbs.

Climb Performance

The climbs are where this wheelset really shines. It turns in the 6th-best time of any wheelset in Zwift, which doesn’t sound impressive until you remember it’s a level 6 unlock at only 150,000 Drops!

Shimano’s DURA-ACE C36 wheels put in an Alpe climb just 1.2 seconds behind the Zipp 454 wheels, less than 2.5 seconds behind the fastest wheels in the game across an hour of steep climbing. Very impressive performance for a level 6 wheelset!

Note: all test results above are from a 75kg, 183cm rider holding 300W steady using the Zwift Carbon frame.

Conclusions

While the new DURA-ACE C36 wheels from Shimano aren’t the top performers in Zwift, they are the best all-arounder or climbing-focused wheelset below level 18. In fact, I’d say they are actually the best climbing wheelset below level 24! Definitely a wheelset Zwift racers will want to check out early in their racing progression.
