 ===Überspringende Hohlradmitnehmer===
+Die Innereien von Brian Hayes 1958er Originalnabe waren verschlissen. Durchrutschendes Hohlrad- und Sperrklinkenrad-Mitnehmer ermöglichten dem Sperrklinkenrad im hohen oder niedrigen Gang aus der Verzahnung zu rutschen (gegen die Federkraft). Wenn der normale Gang eingelegt war, drückte die Bewegung die Nabe in den niedrigen Gang, so dass das Hohlrad hohen Zoll zahlen musste und dadurch die innenliegenden Verzahnungen wirklich stark verschlissen waren. Das führte wiederum zu Abspanungen an Sperrklinken im niedrigen Gang.
-My original 1958 hub's internals had worn, sloping gear-ring and pawl-ring dogs which permitted the pawl ring to slide or "cam" out of engagement (against the spring force) in normal or high gear. If normal gear was selected, this motion slammed the hub into low gear, surely taking a great toll on the gear-ring internal splines (mine were really chewed up) and may be the main cause for low gear pawl chipping. This "camming out" effect may be what Tony Hadland is identifying as the primary cause of trouble with this hub4. Camming out is more prevalent in high gear than normal because a rider typically transmits more torque in a slower/higher gear. As mentioned above in the section on pawls, the slipping of these dogs can be related to problems with incomplete pawl engagement, although even with perfect pawl operation, clumsy shifting can result in partial engagement of these dogs, again leading to slippage.
