Zwift’s Big Spin 2025 kicked off March 3rd, and with it the much-loved prize spinner. One of this year’s big prizes is the “Groovy Time Trial” wheelset, the second tri-spoke wheelset in game.
Here’s how these wheels are described in the Drop Shop:
“Stiff and responsive, the tri-spoke flies in calm weather, while the disc wheel cuts through the air and minimizes turbulence – perfect for time trials and longer rides.”
The Groovy Time Trial wheels are rated 4 stars for aero and 1 for weight, just like the other disc wheelsets in Zwift. This indicates that their climbing performance will be poor, but their aero performance will be strong. Just like disc wheels IRL!
But as with any new piece of Zwift equipment, we ran them through our normal tests to learn exactly how they perform. Because we like precision. So here’s everything you need to know about the performance of the new Zwift Groovy Time Trial Wheels…
Aero (Flat/Rolling) Performance
The Groovy’s aero performance is strong, putting them in the 81st percentile and ahead of all but the fastest non-disc wheels in game. To be precise: while the three name-brand disc wheels (DT Swiss, Zipp 858, and Zipp 808) beat these handily, the Groovy wheels are also outpaced by the non-disc Zipp 858, Zipp 808, ENVE 7.8, and ENVE 8.9.
Their test time of 50:47 is 22 seconds slower than the current fastest road wheels (DT Swiss ARC 1100 DICUT DISC) on our test course, which is two laps of Tempus Fugit totaling 34.6km.
Climb Performance
Rated just 1 star for weight, we didn’t expect much in terms of climbing performance from the Groovy Time Trial wheels! They came in second-to-last in the overall list of road wheels, faster only than the Zwift Tri Spoke // Disc Wheel.
To be fair, these wheels turn in an Alpe time of 49:44, which isn’t much slower than the other disc wheels in game. (The fastest climbing disc wheelset, the DT Swiss, clocked in at 49:37). If you’re racing up a long climb, disc wheels are probably not your best best. The fastest overall climbers in game (Lightweight Meilensteins and Roval Alpinist CLX) complete the test 30 seconds faster than the Groovy Time Trial wheels.
Note: all test results above are from a 75kg, 183cm rider holding 300W steady using the Zwift Aero frame.
Conclusions
The Zwift Groovy Time Trial Wheels are a fun unlock, and not only because you can change their color to match your frame:
While their performance isn’t going to impress anyone who already has one of the top-level disc or non-disc wheelsets, Zwifters below level 25 without access to more aero wheels may see these as a much-desired garage addition for use in flat and rolling races!
