Elixir 3 w/ 165mm rotors

I'm having a little trouble with my front brake system. I'd like to replace the rotor and have just realised that they're running 165mm rotors at the moment - the brakes are Elixir 3s. 165mm don't seem to be available, so I'm guessing I need to adapt to 160mm rotors, perhaps by removing the washers between the mounts and the calipers. Is this the way to do it, or is there something I'm missing here?

    You've currently got a 165mm ???

    Yes. Visibly larger than my rear and also stamped on the rotor.

    Just get 180/5 and get the correct bracket.

    Removing washers from the conical stack is the way that I would do it.

    Just eye it and make sure that the outer circumference of the rotor is atleast level with the top edge of the brake pads as in (A). If not, then the brakes will stop functioning correctly once there is a little wear as in (B).

    Thanks for the diagram. Having looked again, I don't think I can remove any washers as there only two making up the conical stack and I presume that removing those will mean I can't make any adjustment/alignment?

    Yes as that is the way that Avids work.

    Upping the front is a good idea anyway - just buy the correct adaptor.

    What are you expecting to gain by replacing the rotor?
    Clean it with isopropyl alchohol, remove the pads, givec the calliper a quick hose-down, and fit new pads.
    There's nothing to go wrong on a rotor, apart from bending it.

    Quite agree. The reason is that I run tubeless and bought a new wheel to have some choice of tires without the nightmare of changing tubeless tires. I had hoped to put the same type of rotor on the new wheel, but 165mm are not available so I have to change the rotor either to 160mm or 180mm.

    Ah, ok. When you said you had a little trouble, I thought you were trying to correct a fault.
