Many bicycles do not shift correctly or do not follow the right track because the wheels are not exactly in the alignment line. If this condition still persists after adjusting the wheels and gears, the seat tube, chainstays and frame dropouts may not be aligned. This can be checked quickly and easily with the frame check gauge. Only if the gauge, set on one side at the drop-out, fits exactly on the other side, the frame will align. Suitable for all common frame types and sizes.
