It looks like it might be a self-extracting crank, with a flange on the screw that bears on the plate with the hex hole in it as you undo the screw. I'd try undoing the hex screw and see what happens. If it gets tight after a few turns, it's probably because it's starting to act as a puller.

Hello,
Were you able to take it out? Is it self extracting? As you mentioned, it's undo but then gets tight after a few turns I was not sure whether to keep turning. thanks.

Yep the crank bolts are self extracting bolts, what I did with mine was to undo them till they were as tight as I was game, then went for a short ride loaded up the cranks then they came straight of.

Thanks a lot Cookiee. Very helpful. The crank came out directly.

Have you got a Torque Wrench to get the cranks back on, they're tight to pull on all the way home, Norbar make the best Torque Wrench they go up in points of Nm.
