Hye uniQ,
Changed my front derailleur cable yesterday on my DA9000 from whatever the bike mech used (he also ditched the "special" DA cable as it seemed to be sticking for some reason) to a spare Jagwire slick stainless cable, i greased it as well with some light grease i have and it seems a lighter action than it was previously on the shifter.

). Doubt i could do those times in the heat that you're riding in though!
