I think they put just enough to keep the parts from rusting. I don't have a problem with retail store bikes. You can always buy it and take it to a bike shop and have them tune it up. What I also see is people think I only paid so and so dollars for this bike so it can sit out side. I see it happen a lot and even my own brother and nephews. They know I'm the bicycle guy so when something needs fixing it comes here. A lot of the issues come from the setup...if you want to call it that from store.

I've got my 16lb carbon road bike with full Camp group, Schwinn Paramount, but I still have a Walmart bike in my stable too. The derailleurs may not be lightning fast when shifting but they do what their intending to do and still work. The brakes still stop me and saddle doesn't hurt my rear end too much. It's like a Geo Metro and BMW M3 are still going to get you from one location to the next...keep rain off your head and keep you warm(be it both are in good working condition). Yeah you can go buy something better used on CL but not everyone may not know what CL is or anything along those lines. I see more people in my town riding bikes from Wally world then the folks on LBS bikes. It doesn't matter where you get your bike from. Just ride. Yeah supporting your LBS is one thing but you shouldn't feel obligated to dump your hard earning just to ride.
