A rotational velocity sensor ring comprising a circular cylindrical body with a radially interior cylindrical surface, a radially exterior cylindrical surface and first and second cylinder ends, a plurality of substantially equally spaced, substantially equal length fingers extending from the first cylinder end, and on each of the fingers, a substantially 180 DEG bend proximate to the first cylinder end, wherein each finger is radially exterior of the circular cylindrical body, wherein each finger has a finger end extending toward a second cylinder end opposite the first cylinder end, wherein each finger is proximate to the radially exterior cylindrical surface and parallel to a cylinder axis of the circular cylindrical body, wherein the fingers comprise a set of teeth of the rotational velocity sensor ring.
