Seeing a lot of green rear wheels lately.
Have also seen a few purple ones
I read somewhere a suggestion that it was something to do with the type of trainer a person was using. Maybe green for a Kurt Kinetic? I’ve absolutely no idea if that theory holds weight though - might just be a graphical glitch.
i suspect it is more likely a rendering issue.
This is probably the same bug that sometimes results in the Tron bike wheels not glowing. Its a cosmetic issue that they surely know about. Eventually, it will get fixed.
