Zwift Supersonic wheels

I find the Zwift Supersonic wheels are extremely slow, even when riding in Coco’s pack, was yoyo-ing behind at >3w. Anyone else has similar issue?

Thanks.

Zwift insider suggests:

The wheels appear to be a re-skinned version of the Zwift 50mm carbon wheels, but we’ll need to test to confirm.

I found these wheels very slow, like riding in treacle.

More annoying for me, I had them as an automatic selection for one of the Fast is Fun TT’s, and couldn’t swap them out, despite everyone around me on other wheels. I reckon i lost a few minutes of time, on that ride, as I was at least 5 kph on ave, down on my regular wheels.

working as intended
