    Upgrading from 160mm to 180mm

    Any feedback on upgrading larger rotor. I have been look at ebc rotor upgrade kits. I would like to run 180mm up front and the 203mm at the rear, Or is it better to just upgrade 180mm front and rear?

    Larger rear rotor is very unusual.

    Yes, why would you want to do that?

    In every form of wheeled vehicle weight transfer when braking puts weight on the front wheel. Thus you see bigger front rotors on motorcycles, cars and bikes, and smaller ones on the back.

    Most bikes have rotors of the same size although quite few people run a smaller rear one.

    Having upgraded my front on the 29er from 160 to 180 I got a nice boost in power. I left my rear at 140 and it is still plenty strong.

    I think will run that setup. My original plan for the larger rear rotor is since i use it more than the front rotor. Thanks for all of ur opinions

    This sounds like improper braking . . . not only are you not getting the most power our of your current set up, you are in less control and probably damaging trails.

    Work on using your front brake more, feathering it to avoid locking it up and going over the bars. There are a lot of great resources out there on good technique.

    What kind of bike are you running? What front suspension?
    Alcohol may lead nowhere, but it sure is the scenic route!
