What comes off first, middle or outer ring.

I assume outer ring, also what do the tools look like.
Think I have the outer ring on (round thingy with flappy hook on the end)
Not sure what the other looks like.

Although c spanners are probably the most dangerous tool known to knuckles!

 

[Tootyred]

Although that park tool looks great!

 

[Graham_hkr]

Although c spanners are probably the most dangerous too known to knuckles!

Correct...

Thanks, I think I have all those bits.
If all else fails I have a Knipex Cobra that needs to be in every mans toolbox.

Yep outer which is the 'lockring' designed to stop the BB cups from unthreading.
