Park Tool FAI-2 Frame Alignment Indicator

After a crash or accident, a bicycle frame may become misaligned, causing handling issues, shifting problems and wheel installation difficulties. The Park Tool Frame Alignment Indicator measures three points of contact on the frame - the head tube, seat tube, and rear dropouts - to ensure that it is perfectly straight. 39" (99cm) long with an adjustable dropout indicator to fit most sizes and types of bicycles.
