That would be stupid to use on a uni, they are designed and made to lock a wheel with the most force possible, not to brush the rim lightly like you do with a uni. Those brakes are not made for modulation, they are made for crazy lock and hold.
I’m afraid not. Brakes like that are built FOR modulation, not to lock a rim. Any old brake tuned correctly can lock a wheel, but it takes higher quality stuff to control modulation better and make it LESS of an ON/OFF brake. That is, after all, why I have hydraulic brakes on my downhill bike and motorcycle, and I can tell you from personal experience that those brakes modulate way easier and better than the other cable brakes I have.

Trials bikers need the hard “lock” when they go to rear. A strong grabby brake is what they need, and modulation is only secondary. My brother rides bike trials and is always complaining that his break isn’t locky enough (though when I try it, it feels just like my muni).
Oh, sorry sorry sorry, I wrote all that without even looking at them. I just checked the page, and they are trials bike brakes, I thought they were just mountain bike brakes like juicys. Better to look first next time:o
