I just purchased a chain sprocket kit from Drive Systems (http://www.drivesystemsusa.com/ (http://www.drivesystemsusa.com/))
They use DiD chains and make their own sprockets apparently. Pretty good deals...
Anyone here have experience with them?
I've used quite a few of their sprockets.
What did you want to know?
quality vs other "name brand/popular" sprockets.
