Hello, I'm urgently trying to source a right crank for my bike, but I'm unsure whether it's an octolink one or what I should be looking for .The actual make is "Concept" but I have been unable to find reference to it anywhere. The nearest crank I have found is A Miranda Beta-O-Electric bike crank with octalink fitting. It is the exact same shape as the fitted one, however I'm awaiting a crank puller tool in order to see what I have .Has anyone got any ideas or advice?
