There are a few different circlip pliers unfortunately. I have three sets and none fitted my rear circlip! In the end I managed with very long, thin needle nose pliers, and a small screwdriver in my mouth as you need three hands. Then you take the circlip to the bike shop or hardware store and get a replacement one because you have stressed and bent it, and get some pliers while you are at it for in twenty three years time when you next want to remove the damn thing. then you get home and putting it back in place you find that some bit of metal gets in the way of the pliers and you wasted $25 and use three screw drivers in your mouth instead, again stressing the circlip as you pound it back into the groove. Then you ride for a few hours worried it will break because of the strain you put it under. Then you forget and ride safely for weeks and it breaks and your wheel falls off which is a bugger. Apart from the last bit, thank goodness, it all happened to me.
