    changing brake disc size

    I have a 2005 Hardrock Pro with mechanical disc brakes. They currently have 160mm discs on them. Looking at upgrading to a 185mm disc for some added stopping power. Do I just buy the larger disc or do I need anything else?

    Thanks,
    Matt

    You need a different adapter to move the caliper to the proper position.

    When under pressure, your level of performance will sink to your level of preparation.

    Buying a new caliper will almost never increase your rotor size unless going from a front IS to a rear IS caliper.

    So I just need to buy the different mounting brackets then. So from doing some research I've found that I have the 51mm IS mount on my fork. So the correct mounting bracket would then be the one that says "IS 185mm" for both the front and rear caliper correct?

    Thanks,
    Matt

    Front and rear adapters are different.
