here's the 411 on the 500... it has an aluminum steerer tube, btw... and a rather steep 72.5mm head angle... remove the fork, and CHECK that steerer tube for bending, with a GOOD straight edge... and cracks at the fork crown area....... remember those "broken spokes"? and use a magnifying glass to inspect the frame around the head tube, and top and down tubes, about 3 to 5 inches from the head tube...ok?
