They look fine to me. Properly installed and adjusted they should do exactly as they're intended to do, stop a bike.

Decent reviews on them. BTW, the brake I wound up going with was the Dia Compe 990. The freebie bike I wound up with was brakeless because it was removed, so I chose to put a rear brake system from lever to gyro to u-brake on it. Wasn't cheap, you can get close to $ 100 into that at the LBS without trying very hard. Mine works great and am pleased with it. Could've spent more, even could've gone a little cheaper, this is a happy medium though.
Pretty much what I installed:

I bought it thru the LBS and it was pretty much marked up for S&H and a few bucks more for profit. I paid about $ 40 for the Dia-Compe, $ 30 for the Odyssey Gyro and $ 20 for a single Black Ops brake lever. I could've done a little better on-line, but these were locally convenient and a few blocks from home. Prices on those on-line links don't include S&H, but I can't imagine being anything more than $ 6-8 more for each item if ordered separately. Like I said, I think they dinged me here and there for each item a little, shame on them, or really shame on me for allowing it to happen ?
