How do I remove this crankset?

[lxs602]

Hi,

How do I remove this crankset?

I searched for "Gossamer ISIS drive" and I could only find about self-extracting cranksets, which this does not look like.

I only know old bikes. When I used a crank remover, the inner part screws all the way in without moving it at all. Is there some new tool I need?

Thanks

A quick Google says that a normal extractor won't work, as you have discovered, and that some extractors have a special adaptor.

Looks to me like an obselesent BB, I'd lean towards fitting a square taper BB with suitable crankset after releasing the current one with a hammer, rotating and tapping until it comes off.

You need the widget to block the hole and give the puller something to push against.

It's an ISIS BB so uses a standard crank extractor that comes with an interchangeable head, one for standard axels one for ISIS. The ISIS head is larger. Park do one (I have one). Just Google ISIS crank extractor and you see.
