When i installed mine, the axle was a little rough to turn at first. After a few minutes of riding, it seems to have loosened up just fine. The only question i have about the axle, is the spacer on the brake hub side has a little free space to move. Everything is tight, and the axle is not moving side to side, yet this spacer is moving a little bit. Anyone else have this issue? I have been beating the crap out of it, and everything still seems fine.
