    What do I need for Shimano XT brakes on Karakoram 3.0

    Hey guys,

    I just bought some Shimano XT brakes for my Karakoram 3.0. I need a few things though. I'd like to run a 180mm front rotor but don't know much more ( I'm fairly new to the mtbiking thing). What adapter do I need and can I use my original tektro 160mm rotor for the year or do I need shimano rotors?

    On most forks you need an adapter to go from 160mm to 180/185mm on the front. Is your fork post mount or IS mount?

    Yes you can use the same rotor on the rear. I would get a new one (new brakes, new pads = new rotors IMHO).

    You will need a 180 adapter for the fron and a 160 for the rear. Sorry I don't know the part number, just know that it will say R-160 and F-180. R meaning rear and F meaning front and the size rotor it works with. The rotor ou have will work for the rear

    like this but for 180mm

    You should be able to reuse your rear mount.

    Deore level, SLX or XT It's your money.

    If you are using Ice tech pads then Ice tech rotors.

    Are your XT brakes 2012 or 13?
    Ice tech pads?

    The "finned" pads are designed to work best with the icetech rotors. Normal rotors will probably work. You spent money on fancy XT brakes might as well use the rotors designed for them IMHO. The 160mm Icetech brakes stop very well by all accounts.

    Other people mix and match caliper and rotor brands. I don't. YMMV

    You can use whatever rotors you want and/or reuse the front rotor n the rear, or not.

    Icetech rotors are spiffy, but über pricey. Same w/ icetech pads. Unless you have had issues with brake fade on long descents, you don't need the icetech stuff.
