Removed rear wheel today to wash my Rise M10 and noticed as I pulled the axle out it brought the plastic ring with it that holds the rear derailleur mounting kit in place . It's the part that says to pull and twist on the frame . On looking at it it's stripped the plastic tabs / guides inside the plastic ring , so it doesn't twist and lock anymore . It's not going to cause anything to drop off once the wheel is in place but its a bit of a crap design , wondering if it was ever fitted properly because it also had a slither of plastic that had come loose . I've been careful with it since I've had it , its my first carbon frame so I bought a torque wrench as soon as I got it . I'll include pics , but just a heads up to keep an eye on it .
