• Why not just go for larger discs? I know it's uncouth, but 203mm rotors on downhill bikes rarely get warped.
    Still don't get the obsession on road bikes and 140mm rotors.

    Aero I can't understand, but that rather than heat dissipation I don't!

    Two thing, weight, and the flat mount designed for 140mm without adaptor.

  • The latter doesn't really hold much ground tbh. 160 all around and happier braking. How much more does a 160 rotor weigh anyway
