Can I ask why you want them replacing? If they are loose in the frame it is possible in many cases to "pull" them up to retighten them.
You can get a tool for this or bodge one.
Thanks for this. I don't know much about them so assumed once it was loose it needed replacing. Also this is a pretty nice frame (very thin walled Ti) so don't want to do any bodges that might risk damage. But seems a lot more straightforward than I thought.
