The Revolution Velo Racing Kit is the reward for completing any Revolution Velo group ride in the on Zwift. Simply complete any event with the Revolution Velo group to unlock the kit.
Apparently the Revolution Velo group exists for female riders, or those who identify as female. I obviously missed that message!
The Revolution Velo Kit is super cool though, and consists of a black jersey and shorts, with contrasting fluorescent lime, pink and sky blue features.
