I lube and clean it a least weekly. Lube with Tri-flow.
I do ride in the rain on occasion which with this particular chain has been once (last sunday) But I also ride fairly early and near the coast so there is quite a bit of moisture (marine layer etc)
I believe I am considered a masher (average cadence is 75-85)
This chains life has been about 50% of the mileage climbs
