Thanks for the replies. I am trying to understand what is being said here and looking up some of the terms on google. I am trying to learn about bike maintenance one step at a time.
I found http://www.cheapbikeparts360.com/pro...ottom-bracket/ based on Jim's recommendation. I cannot tell if it is for a MTB or a RB.
I am headed out to church and look forward to reading more about this when I get home.
