I'm working on my first build, picked up a Genesis 29" mountain bike from Wally world on clearance, $160 after tax! pretty good deal I thought, since it's $220 normally. I'm gonna put a china girl on it. it's got disk brakes up front and the brakes levers are built into the shifters. it's super light weight due to the aluminum frame, but the frame is kinda small so some modifications will be needed. I'll upload some pics tomorrow.
