    The axle was a little oversized at the splines for the brake rotor, and where the bearing land on the axle. Had to file them down. At $69 vs $500 for a name brand axle, I guess you get what you pay for. It is nice and shiny and seems to be beefy enough.

    I haven't done any hard riding on it yet, just around the yard to test all the new parts out. It was an easy installation, looks good and seems to be good quality. Good buy for the money.
