i've got a cassette tool on the way to change out my centerlock disk rotors. torque spec on the old & new parts are 40NM.
do i need to brace the rotor to loosen, tighten and torque it? or just hold the rim/tire?
any tips or tricks for this?
should i flush out the gunk from that part of the hub while it's apart? dry lube? or just wipe it with a rag?
