Does anyone know if a puller is required to remove crank?
I have removed locking outer bolt and inner holding bolt but the crank failed to come off. There doesn't seem to be anything else holding it. I have tried a firm tap but holding fast

    Put it all back together... (it's self extracting you see...)

    Use a 8mm allen key on the inner holding bolt.. and the crank arm should fall off.

    I think I get it now, you leave the outer 10mm in place and pass thru that with 8mm and undo that and the outer pulls the crank with it, is that right?
