Rotor Size

Hi folks,

how much of a difference do you find when moving to a larger rotor?

Currently have quad qhd-1 hydros with 160mm rotors, but have just picked up a set of deore m595's today and just bought a 2 pack of alligator rotors on fleabay. My only concern is that the only ones they had left was a 2 pack of 203's. i was thinking of getting 180's or maybe a 180 back/203 front but have ended up with 203's front and rear.

Are 203's at both ends likely to kill me?

cheers

    Depends if you slam your brakes on a lot. You also need a caliper mount thingy to fit bigger discs, I think.

    Given that the Deore is one of the most powerful brakes on the market, the 203 might make them too sharp.

    180/160 for an average weight rider on average trails.

    censored , should be interesting then. (maybe i should invest in a superman costume for when i fly over the bars :lol:

    i tend to feather the brakes as i like to carry a lot of speed, i suppose i'll be able to one finger brake quite easily though.

    I've seen many a bike with 203/203. I use 203/185 on my AM with Avid Code squeezers
    Be gentle and they will bring you to a controlled stop, be zealous and you will wash out or faceplant..
  • ive got a 203mm tektro auigura on the front, and 160mm on the rear. the front stops like hitting a wall, and i replaced the 160 (which was on the front) cause i couldnt stop it with that
    so yes, a 203mm rotor makes a huge difference over a 160mm
