• I have a cassette tool you could borrow, just need to find it.

    When you say "chainring bolt spanner", do you mean a torx driver? If so, I have one.

    I'm in E17. I'll have a look in the next hour or so.

  • Wonderful, cheers. Might be easier even if I cycled round with the wheel and cassette, lockring finger-tightened so could just use it there and then without taking it away - if that's ok.

    Am sorted now for the spanner (meant the notched screwdriver for holding the slotted nut in place but 2op piece seems to be working).
