my components are actually sliping from my carbon frame, the FD sliped literally turned completely towards the inside of the frame, I wasn´t to fast so it was ok, but I will definitely use a friction paste and re assemble this bike. The components I bough somehow came in this small plastic bag, and without absolutely no extras stuff I already cutted 0.5 mm from it and it seemed to solve it but still slipping out something to do with the frame I guess...
