I am wanting to put bull horns on my Fremont, but the stock brake levers that are on there looks like they have a different type of screw to tighten/losten them. It looks like a 3 parts instead of a standard philips or standard head on a screw. Anyone know what this could be or if im looking at the right spot?

2. I am debating whether or not to keep brakes, how many of you use brakes on your fixed gear and how many of you dont?
