Bracket Bottom type and how to remove it? I can't seem to find what kind of bottom bracket I have on my bike and how to remove it to put some grease on/in it. My bike is a Schwinn Cadence 2006 mountain bike.

Right side (crankset side) above

Left side above (with a bit of threading)
Any help would be very much appreciated ! Thanks.
This looks like a standard British bottom bracket with a fixed cup and adjustable cup.
This article gives a good overview of how to service. It looks like your lockring is missing. Also, it doesn't look like you'll be able to use a pin spanner on the adjustable cup. Not clear from the photo what kind of wrenching affordance the cup has, but it should have some kind of wrench flats, so possibly this kind of tool is what you need. Also note that the fixed cup can be extremely difficult to remove.
