Who's tried one of these? http://www.lowbrowcustoms.com/drilled-sprocket-brake-kit-sprotor-black-caliper.html

I want to know if it works. I cant imagine chain oil on a disc being particularily good for pulling a bike up. Oil can be good for pulling somethings up, just dont think a bikes one?

Thoughts?

Whoop whoop thats the soud of the police! Theres plenty of ilegal shit, but doesnt really stop us now does it. And when you talking pre compliance who cares? 

So back to the question, whoes tried them, do they work?

you need to run o ring chain on sprotors
