What tool do I need to get the bottom bracket bearing cups off my bike? Surely there's a tool. I've taken a picture of a bearing cup from my bike viewable via the link below.

It has to be easy with the right tool. Any help would be appreciated. Thanks

Its right here .

What's the size of the Park HCW-11? Would it fit a 15mm step on the bearing cup?

Here is the complete information for the HCW-11 from that Maker. And yes it would fit 15mm. http://www.parktool.com/products/detail.asp?cat=25&item=HCW-11.

There is another such tool but costs more, I have one and it is very nice,

Ye and you can always use a one size fits many adjustable wrench if you got one on hand. And actually parkstools makes a 12" one I just got, along with a steering head wrench. Carefully.
