    Ah yes, ideally you need a c-spanner, either adjustable or a fixed one of the correct size. Now I shouldn't really tell you this as more lock rings have been damaged by using a hammer and punch to undo them than there are stars in the sky, but you could try a hammer and punch.....gently!

    However, slackening the lock ring is half the problem, then you have to undo the adjustable cup. I can't see from the picture which type you have, but it will need either a pin spanner for the holes, or a thin spanner across the flats if there are any.

    on the other side is a metal ring which looks like the plastic version that are on shimano BB cassettes I also have the tool for removing this as well I am hoping that this is a cassette assembly rather than ballbearing and races

    fair advice but can you tell me if this is a sealed bb or a ballbearing race and ballbearings

    Personally, I have never come across a cartridge BB with a lock ring.......but I live and learn.

    That looks like a octalink cartridge BB to me.

    You need
    the right size allen key
    crank puller
    and a spanner to undo the BB cups

    Its an easy job but if you are rarely going to change the BB, the price of the tools make it expensive.

    have just checked the crankset again and there is a number stamped into it fc 5500/5503 so looking at it it must be an octalink BB
