If you want chain cleanliness, use WD40
. If you want longevity, dump the 9 and 10sp and use 8 or less.
Stainless(copper core(aluminum inside is choice... stainless for heat transfer and wear life, copper for heat retention and aluminum for its non-conductivity and non-reactivity.
unfortunately that combination is very heavy and would never catch on in Pro cycling... I for one would be highly surprised to see a professional rider win a stage in The Tour while on a bicycle that had more than a fart's worth of copper. And steel has been passé for long time in major frame components, or so it seems.
