Crank removal tool

surball

I am in the process of building up a new frame with some old components from another bike. I am trying to figure out what tools I require to remove my crank.
I have attached a photo of the existing crank.

Is this tool compatible?

No.
You need an allen key, I can't remember what size.

Probably an 8mm or 10mm allen key.

They look like original hollowtech cranks, so yes you will need a hollowtech-compatible crank extractor too. I think the one in your link will work.

Can't quite tell from the picture, but if that rubber looking thing is in fact metal, the crank may self extract by just keeping undoing the allen bolt.

As far as I can remember, the Hollowtech cranks have a larger circumference hole for the axle than the older square-taper cranks. Some of the crank puller tools are designed for the latter, and they are too narrow for Hollowtech, that Lifeline tools looks like one of those. By comparison this crank puller by Park Tool has a wider diameter where it bears against the axle and will work for Hollowtech (but not for square-taper, in case you care about that).

The appropriate tool is available from other brands too, of course, not just Park Tool. You can also buy adaptors for the older/square-taper tools, basically a lump of metal with a wider diameter at one side where it bears against the axle and a narrower diameter at the other side which the crank puller bears against. Some bottom brackets even come with the adaptor, any FSA Hollowtech bottom bracket I've bought in the past has had one in the box. That turns your square-taper tool into one that'll also do Hollowtech.

Actually according to this review that Lifeline tool might have a removable tip so that it works for both square-taper and Hollowtech. It says it is compatible with Octalink but it has been a while since I've dealt with such cranks and I've forgotten the terminology so can't remember whether Hollowtech and Octalink refer to essentially the same design.

As Doozerie says It should come with the attachment. The ones in the Halfords basic tool-kits have a extra piece .
