I got to practice carbon repair on a frame because of my own mistake. I got an aliexpress carbon frame based on the early 2020's Bianchi Infinito.
it was wrapped so tightly I had to use a knife to remove the bubble wrap and I scratched the finish on the fork. I had to sand that down, spray a French flag graphic and polish.
Next problem was the bottom bracket. It called for a bb386 which is pushed in. My press tool made short work if that but the bearings did not spin freely at all. I thought maybe the bearings were gunked up so i tapped them out to check. Theya were fine. So i tried to fit them back in. Turns out the frame bottom bracket shell was too tight and the pressure on the sleeve prevented the free spinning of the bearings. I wish I realized that because one crank too many of the press tool cracked the frame.
Fortunately I was able to repair it just fine but it also necessitated the painting of another graphic to cover up.
