86 RockHopper,2008 Specialized Globe. Both upgraded to 9 speeds.
Identify the bike and componants in question the best you can. There should be at least "some" names & numbers. Also number of chain rings & cogs.
How many "arms" attach the crank arm to the chain rings?
How bad is the crank. IF the pedal is a 1/2" thread, it could probably be drilled and tapped for a 9/16" thread. That would be much cheaper than replacing the whole thing.
3 Probably not
4 I think you mean shifters. Probably not
5 I certainley wouldn't attempt it as by first bike repair!
