Thanks for replying, I messaged ChasnotRobert about the tool but if that can't happen for whatever reason I'll be back in touch - but really appreciated.
As for the seatpost, inline and fairly cheap and cheerful are important, say up to £15, hopefully less....
I have a Shimano Cassette removal tool you're welcome to use in E14, regarding the post, layback or inline and do you have a budget in mind?
