I have these cyclone cranks which I may fit to a Ku. I’d planned to go RF or maybe M952 but theee have fell into my lap and are different.
They need to be black however. So one option is to have them anodised. (I’ve a guy)
But …. Are the black cutouts anything other than just paint? I assume it’s paint just to give contrast but didn’t want to send them off and realise it’s something in the core of the crank.
Also there isn’t much info around on them. Anyone know much apart from the 1 catalogue pic online.
