But probably not in use on bicycles. As Brommers was saying, the very maximum stopping you can do occurs just before the wheels lock, hence ABS as you'll know. So if you can lock the wheels with a 140mm rotor, a 203mm aint gonna stop you any quicker
Don't ask me about forks tho
I've put a 203mm on the front of my cargo bike because there's no chance of me doing an endo on that and with a 2.1" slick tyre, losing grip either
Cargo bikes are actually one of the most interesting instances of this issue because the short fork, and large mass meaning you can put some serious stress into the whole front end. With a road bike, meh, stick whatever you can fit you’ll be grand.
