Are Heavier Wheels ACTUALLY Slower? | The Results Surprised Me

Everyone thinks expensive carbon wheels are faster simply because they’re lighter, but the reality is much more complex. In this video, we put that theory to the test by comparing a standard wheelset against one artificially weighted with an extra 238g to see if there's a real-world speed penalty. We also sit down with a wheel expert to discuss why rotational mass, aerodynamics, and even your tire choice might be more important than the weight of the rim itself.
