I rebuilt my BB, wheel bearings and the pin wheels on my derailleur with a lot of excess grease in the first two items. When it warms up, I will rebuild my headset.

My bike melts off at work everyday, and I occasionally hose it off there too, being careful of where the water goes- I froze my rear d cable once.

I lube my chain alot when it is sloppy (like yesterday and today) otherwise it starts to skip. I started using wd40 instead of the expensive lube I use on my road bike.

I plan on thoroughly cleaning or replacing my chain in the spring. I will also rebuild everything again, and wash the bike.
