chained derailed a couple of weeks ago at a race, no damage, the rear bearings where shot we figured thats why she derailed, replaced the bearing, seals, sprockets, and chain. but last week she derailed again, have checked alignment, everything looks good, may have just been bad luck, any one had any problems with derailing, what kind of slack should I be running. I usually allow about one inch of slack. having carfully check the chain slack thought the complete suspension travel it looks like I could set the slack at about one half inch. any thougths. any one else had any unusual problems? thanks Bill
