I’d try that before whaling on it. There a silver allen bolt at the bottom with a black circlip in front of it amd two other allen shaped holes at 4 o’clock amd 8 o’clock.

Hi, Unfortunately as we have never sold your bike we have no way of knowing if this will fit it or not I’m afraid. Plenty of grease around the edges of it from when it was put together so don’t think t would be seized, any ideas for future reference?

IIRC it is usually the case that one or both wedges are held captive to the assy by the overhanging heads of the button-headed screws; it idea is that once one wedge comes loose the other can still be released OK. So I loosened the key a bit more had another go, really pushed hard.

I bracet want to hit the allen key to unbind the wedge for fear of knackering the threads but I can’t think of any other way to get it out.
