Im looking to get a custom crank made for a bike and found a press-together with rods that don't use bolts. I guess you put the rods on & then press the crank together in sections. who has used or has experience with these? what can you tell me about them?

 

::::

so no one has used one? I know they use them in some MX bikes and in the 40K RPM nitro RC cars. from what i found today, they make them for 4 cylinders too.
