Looks like a great idea but, I see a problem, straight from china.

Stick with stock, went though 4 sets of all balls in a month and a half, and the diamond racing is also garbage and inner race is made from soft steel that eats it self right up. Diamond racing is by far worse than all balls. If inner sleeves are still good buy INA bearings, they hold up very good.

Neat, I wonder how much money he has dumped into it.
