I didn't say throw the bike into the dump! If you give it to a needy kid it will get another riding a bike (helps environment). Buying a new one helps the economy, provides jobs etc. makes you work harder to pay for new bike. Hard work is good. New bike makes you smile and the mfg smile and in the process you made a kid smile. Smiling is good for the environment. Simply properly adjusting the FD doesn't make nearly as many smiles.
