It's the stock brake. This was an imitation mountain bike. The reach is RIDICULOUS! It's not even a real brake no matter what I do to it. It only gives you the illusion that you're slowing down.
Since it's a single speed I'm not likely gonna be going up and down hills on it but I still would like some stopping power. I do have a spare front road wheel I could put on and I've sourced a front non-recess brake caliper for $18 shipped. So I might go that way if I feel fancy.
