Outdoors, and closed course meaning we're not taking them on the road to race them. We did the same thing with our street bikes but made too much noise. Its not a circle track, its a small track made using cones and the islands built into the parking lot. so lots of left and right turns, straight-aways and lots of tight turns.

In Replay to the comment about road bike riders sing front brakes all the time, i know. I use mine often because the rear brake isn't enough to slow the bike down.
Andrew Stewert, i came to a forum for suggestions on parts that are made for bicycles. I never said i wouldn't take suggestions.

We're all using frames with built in gas tanks because they fit our needs a little more. I did take a look at some of the different parts that were suggested and i'm going to go with a double disc in the front, and the saint brakes look good. i think we will go with those. I don't know a whole lot of the parts that are out there because i am fairly new to building bikes( i built all 6 of them myself since my friends didn't know how to do it) and i wanted some help. I'm a computer nerd, i build high end desktops, and read every hardware article i see. but i've never treated someone who knows less than i do who might have strange ideas with disrespect or outright rude behaviors. some people just don't like things that are different. Thats fine, but you don't have to act like tools.
