I won't t say I think you are lying, just agenda driven and misinformed. I would recommend asking the people who own such bikes and use them; not dealer's self serving recommendations. Do you also shampoo your hair, rinse and then Repeat because the directions recommend such a wasteful practice. Perhaps you wash and wipe down your bike after every ride too. I'm sure some anally retentive mechanic might recommend it.

I own three Sachs/SRAM Specro 7 equipped bikes. I commute on one as I previously posted. One daughter commutes daily in Chicago on hers, the other daughter uses hers for getting around Philadelphia where she goes to school. Our take on your "maintenance and efficiency rants?" Baloney!
