You generally don't have to ask people to be cheap, they do it on their own. That is why Shimano and SRAM put their name on garbage from wally-mart or targét or even low end bikes from the likes of Specialized, Trek, Fuji, Cannondale, Jamis, Marin...That is why new modern bikes still have freewheels instead of cassettes or are using loose ball components of no quality. Not all cyclists are cheap but it seems like there is a huge race to the bottom instead of floating at least in a nice comfortable middle or moving towards the top.

Granted though my commuter bike was made with a bunch of mostly free parts but of decent quality. I did buy a new frame and wheels (and rubber) along with chain and cassette and I did get new matching levers and a new rear caliper to replace the garbage rear one but it was more a want to use all the parts I had collected rather than just being cheap.
