pws, 5 months ago @moira I haven't worked on that crank before but based on a tiny amount of research I think it's an ISIS drive crank that does not have a self-extracting bolt, so you would need an 8mm allen key and a crank extractor that works with the ISIS standard. https://www.parktool.com/en-us/product/crank-puller-for-splined-cranks-ccp-44
