Your bike frame and wheelset choice both affect speed in Zwift, but your wheels affect it the most. While frame choice may change your 1-hour time by ~20 seconds, wheel choice can change your time by approximately ~60 seconds!

So go ahead and pick whatever frame you’d like. But make sure you’re running some fast wheels.

Wheel Tests – Introduction

While Zwift’s 4-star rating system for weight and aero is simple and easy to understand, performance varies even among wheelsets with the same star ratings–because the stars are just an approximation.

So we’ve ranked all the wheels against each other based on their actual performance on flat roads (2 laps of Tempus Fugit) and a long, steep climb (Alpe du Zwift).

Wheel Timings

This chart shows actual timings for flat and climb tests, in seconds. The shorter the bar, the faster the wheels.

  • Flat tests run on 2 laps of Tempus Fugit at 300 watts steady with an isolated 75kg rider 183cm tall, using the Zwift Aero bike frame. This test data is used for all flat results on this page.
  • Climb tests run on Alpe du Zwift using 300 watts steady with an isolated 75kg rider 183cm tall, using the Zwift Aero bike frame. This test data is used for all climbing results on this page.

Percentile Rankings

Trying to choose a wheelset based on timing data can be a mathematical nightmare! Yes, you’ve got our timings above. But how much of your race is uphill, how much of it is flat, and how long is the race?

Percentile rankings make it easy to compare wheels against each other and spot the top performers.

Wheel Percentile Rankings, Stacked

This format lets you easily see how wheelsets perform across both flats and climbs, and compare that performance with other wheelsets. This is useful for planning your race strategy.

Example: you want a top-performing wheelset for a road race up Alpe du Zwift, so you look at the longest bars. But you know the race will be won or lost on the big climb, so you go with the ENVE SES 3.4 wheels since they are near the top of the climbing rankings and also offer solid performance on the flats.
