Oh, thank you for the sage advice, newbie! Show me where in my posting did I ever say that those brakes weren't able to stop me. In fact, if you had read the posting at all, you would've seen that I had clearly stated that I never even took the bike out on a test ride with those brakes on. You would've also understood that my frustration with the calipers was never because of their performance (or lack thereof, because I hadn't even tested them,) but because I wasn't able to adjust them properly due to the manufacturer's design and build choices. There's a reason you didn't understand, abd that's because you didn't bother to read what I wrote.
