It's a Sprint Veloce, it got seize immediately after rebuilt and I managed to unseize it while running. By the way I have also a knocking on the rear hub, and I feel it on my thumb on the videowhat do you think it is? Videos bellow: https://photos.app.goo.gl/B8AhhPHptsffXLa66 Thank you!

Can you confirm that i was torqued into spec as well? IDK... if it is torqued correctly then I am at a loss.

They DO NOT SHEAR OFF! Did you lap in the flywheel onto the shaft? Have you done a run-out test to see if it is spinning round squarely
