removing a 3 piece crank??
Was wondering if anyone can help me.. how do I remove the sprocket side of a 3 piece crank set of this nature.. see the picture, thats all I can get off, I gather the other side is threaded too, as there is a piece that looks like you're supposed to thread off right behind the sprocket I think, its all round with a small flat area, but no wrench I have could ever fit in there, I guess you need a special tool?
PS: that other piece behind the sprocket is just a chainguard holder, dont let that confuse you.
PPS: I think these stupid threaded 3 piece cranks were invented to keep bike shops in business cause they cant be maintained with normal house hold tools and people like to complicate things!
