it would help to know what components are on the bike, 2019 allez can go from claris to to 105 and looks like as normal a mix of brands shimano, praxis, tectro, sunrace
I don't understand bearing gone on rear wheel, need a new one, unless if ball and cone, the races get destroyed or if cartridge surface got destroyed by not good repleacement technique. any time you don't understand, get the shop to explain in detail
again really hard to diagnose remotely
I like park videos for learning
