Q:doo you need a certain kind of grease for bearings and all that for a bike?
The grease you use will depend on where you live and the temperatures you reach. Hot climates will be good for most any grease. Wet areas you need waterproof grease. Shops in cold weather generally use synthetic to prevent the grease from getting too stiff. For general purpose use I have always sworn by Phil Wood waterproof grease. It's durable, blue (so when it turns black it's time to change it), and cost effective. For seatposts and stems I use white lithium grease. It has anti-corrosive properties and is available at any car parts store. Plus, when it turns from white to black, it's time to change it. On these components a little goes a long way.
