Frame alignment gauge

The FAG-2 has been discontinued and superseded by the FAI-2.

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