I need to replace the BB on my 2005 Trek 1200, with a Bontrager Select crankset.
I have removed the bolts, but am staring at what is left and can't figure out what sort of cranks they are.
Before I start bashing away, can you tell me what I am looking at and tell me how I am supposed to remove them?

Is it ISIS?
ISIS I would guess. Top hat bung in the axle end and a traditional crank puller.
Step 1: Cut your thumbnail. I've just thrown up.
If I deploy the traditional crank puller, there is nothing for it to brace against in order to extract the crank.
Unless I using it incorrectly...
There will be a puck that rests on the BB axle.
Wedge a 5p in the hollow then use normal extractor,worked for me .

Like this, though I don't know for sure if the Octalink one is good for ISIS.

You could try bodging with an appropriate sized coin but can lead to a screwed up "mangled and unremovable coin" situation.
Two 5p's if your puller doesn't have the easily lost top hat thingy, and try to be [i]sympathetic[/i] to avoid the mangling problem said above
