my three wheelsets:
downhill 26": KH rim, KH hub, 3.0 tyre, 135 cranks
CC 26": Mavic Rim, mad4one hub, 2.4 tyre (not the one on the pic), 155 cranks (will change as soon as possible)
CC 29": KH Rim, schlumpf hub, 2.5 racing ralph tyre, 155 cranks
brake: shimano slx, changed know to the XT, both wor very good.
no problems with all setups (i’m riding most the downhill setup, also for uphill 
), just the pads wear down quick because the disc gets pretty hot, guess i should brake less 
i love my disc brake system!
