I'm not saying the brake itself is shit, just the performance is, my front discs have always been amazing, I just have no luck with rear
It's a lot better now, can be temperamental at times but I've moved my reach in and I'm getting more power out of it.
As for the front wheel all the spokes are tight and the wheel is still true after 3-4months use, trying controlled stops it flex's and shudders a bit, might be forks flexing though.
