unless you lot can save me. Last night, I posted pictures of my cranks and asked what I was looking at as I was unable to figure out how I was supposed to remove them.
I have since tried my traditional crank puller, to no avail, and even bashed the $hi7 out of them with a rubber mallet thinking that somehow this would help.
They haven't moved, and I even think they might be laughing at me.
So, is there something else I can do? Or is it a trip down the street to visit my friends at the LBS?
As someone else said - looks like ISIS cranks. You need to plug that hollow axle with something to be able to get a traditional extractor to shift them. 5p does seem to be traditional, but anything that will solidly span the hole in the hollow axle to give something for the extractor to push against will do.
If they've been on for 10 years then they may well be very reluctant to move and require (a) the correct tools and maybe (b) some heat applied to the crank arms before they'll shift. If you can arrange a solid plug for the extractor then try heating the cranks up (boiling water, heat gun, even a hair drier on full belt).
Oh and rubber mallets are rubbish on proper stuck stuff - need something more solid/brutal 😉
Does a standard crank remover fit those threads ? If so I've got a plug that should fit the axle. I'm not doing anything this afternoon, email me your address if you want me to have a look.

Ball-joint splitter ftw
Thanks very much for that, taxi25. My son volunteers at the LBS and has now taken the bike in. I didn't see your post until now, but really appreciate it.
To the rest of you, I did try the 5p piece trick, and even doubled up the coins, but all I did was to squash four 5p pieces.
The one benefit from all this is that we now have 4 5p pieces that are shaped like very small medieval bowls.
I've got a grinder you can borrow.

Best of luck to you.
Loosen the bolts, then ride around for a while.
Just pop on an extractor and unwind the bolts. This will push the arm off.
is there a motor in the seat tube preventing crank removal?
I had the same issue with an ISIS BB that had been in my frame for 10 years. Only the correct BB tool would get the bugger out... At the bike shop.

Not on an ISIS. That is what the extra twiddy round coin on a wee stem is that you get with most crank extractors.
Or a 5p.
Or if they are SRAM/Truvative, they have inbuilt self extracting bolts. Loosen the outer soft alloy one a turn, then.use smaller hex key to undo inner bolt - in doing so, you push the crank off using the soft outer bolt surface.
Just noticed in my original post I didn't add the key word - extractor "cap"
They work on the kcnc Isis bb and crank I have. Also the onone fatty I have with original crank set up.

+1 to this. Using a crank puller won't help much if it is a self extracting bolt. I had a Truvativ ISIS crank and it worked as matt says.
