    largest rotor size?

    Hey so I have an Iron Horse Quantum 2, and right now it has Hays mx4's, but i feel like i dont have enough stoping power, and yes I have adjusted the brake pull. Would a larger rotor help? I dont really want to upgrade to hydraulic breaks right now.

    Thanks

    Chris

    I have 160mm rotors and 100mm travel fork, Its a Rock Shox dart 1. would 185mm rotors fit ok? I know i would probably have to get longer bolts for the brake itself.

    I know on my Dart3 the max recommended rotor is 160mm so I'd guess it's the same for yours.

    Max rotor size for the Dart is 165mm (to include older Avid Mechanical brakes)

    Yeah 160mm is the largest size you should use on your fork. I ran a 185 on my fork for a while and didn't have any problems (that I noticed) but ended up switching it back anyway.
    If it ain't broke, fix it 'till it is.

    Sure can. Just make sure you get the right adapter.

    Go with a 185mm front rotor and leave the rear as a 160mm, you dont need a bigger rear rotor to skid up the trails.

    Assuming the frame has clearance for it...which some don't

    But its pointless to run a 160mm rotor up front and a 185mm rotor in back...70%+ of your braking power is up front.

    Maybe consider some Avid BB7's as a simple upgrade
