I can not keep the rear disk aligned I install the weel proper on the ground thighten the skewer as good as possible, then align the break with feeler gauges to be very well centerred brake a few times al great ride, a bit still great, hammer once or twice and the brake starts dragging on climbs. Once I nocticed that the wheel bearing had play fixed that. The problem remais. I am using Juicy seven crossmax xl. I wish I had a thru axle.
