It's a specialized stumpjumper rockhopper, something like that. The extra chainring will be grinded down and turned into a cheap bashguard, as far as the brake, below is a more detailed pic...the rear brake basically sucks ass. I love on my front brakes. then again, it could have been how I had my weight seated since I had no saddle. Oh well...here is a better pic, I think it is a U brake...Either way the brake looks odd
