Hi all
I am restoring an old mountain bike and want to take off the cranks but my normal crank removal tool doesn't appear to fit these cranks. I have attached a picture.
Any ideas?
Thanks
Robin

You have to give us more info other than one cryptic close-up.
What type of crank is it?
What type of BB is on there?
Is that black ring in the hole a washer?

From the picture and looking at the 7-speed chain on there and stamped steel chainrings, I suspect it is a cheap crank and therefore square taper. But I don't have enough into to say for sure.

Looks like a square taper and you've already undone the bolt. If it is, better phoyos please, then you need a crank extractor tool

And when you use that crank extractor, make sure that the inner part is fully retracted before you screw in the outer part. If you are foolish enough not to take my advice then you might do what one pathetic idiot I know did (:whistle: :blush:) and merely extract the thread from the crank, leaving the crank where it was ... :laugh:
