I have the brakes with a 203mm front set-up but the Ice rotor is a little warped and too thick for new pads.

I would like to lose the adapter and drop a rotor size, applying the caliper post mount directly.

Is the size 183mm for the front as standard or 180mm?

Ive tried searching but cant find an answer

180 as standard, though tbh my The Ones sit marginally “tall” and so possibly a 183mm rotor would work just as well

I think I have sorted it, 160 as standard so will need adapter anyway.

So might keep the massive dish
