    Indulge me please ūüėČ

    For a project I may require a way of mounting chainrings to a BB axle without a crank.

    Does anyone know of a spider that mounts separately to the crank? Maybe something for a jackshaft / recumbent / insert other freakbike type setup?

    Pinion chainrings/spider?

    Other gearbox brands maybe?

    Or one off an ebike motor?

    Any chainset and a hacksaw?

    Profile do chainrings that spline fit to the 48 spline Profile BMX axles. Would that work, or do you need a spider?

    Edit ‚Äď they do spline drive spiders too.
