Great for a non-performance application (maybe for performance too, but I can't speak to that)!
I bought a cheap, 20" wheel BMX bike for my niece off Craigslist because she'd outgrown her 16" wheel bike. The bike needed a little bit of work including new brake pads, especially for the rear. I threw a set of these on and it made an amazing difference in the braking function. She's new to hand brakes (her previous bike had coaster brakes), so I opted to leave the existing brakes on the front wheel. They worked well enough, and wouldn't pitch her over the bars if she grabbed a handful by mistake. For the rear though, these can easily lock up the wheel if you grab hard enough, yet give decent modulation if you ease into them. These certainly won't be tested for performance in this application, but if you need brakes to simply do their job for not much money, these'll do!
