this afternoon, as i pulled into the parking lot of the cafe where i work, i'm not sure what happened exactly, but somehow i got flipped off my bike - stupid user error, as they say, i'm sure - anyway, i was perfectly fine other than a knick on my shin, but my bike had thrown its chain and on further inspection, i realized the chainring was bent.

here's my questions: first, do i have any SAFE alternatives to buying a new chainring? if not, no big deal, i can pick one up tomorrow when i'm in the city - i'd just like to know if i have another choice...

second, do i have anything to worry about as far as the crank arm spider being bent? i have sugino rd's if anyone would like to weigh in on it... i sort of eyeballed it after taking off the chainring and it looks ok (i also tried to put a piece of metal flesh against the different parts where the bolts would attach, and all seemed ok) but is there any sort of test short of just putting on the new chainring that will tell me if i have a problem? how difficult would it be to bend the spider anyway?

thanks for the help!
