I've thought about building a bike, for about 10 secs. I just don't need the aggrivaiton. It's alot easier to just write a check for a bike that's good enough. If I were wildly competitive, and the bike made the difference in winning and losing. I might build a better bike. Until then, mine is just fine. Even at 210 lbs, Nothings broken after 2 years. I used to go through cranks, spindles and pedels as a teen. But I guess they make them better now.
