well, i bought the shift kit and found out that it came with an axle that i believ goes between the crank arms of the pedals 
it goes pedal > crank arm > crank ( within the bike frame ) crank arm > pedal
that middle crank axle is what i need to change, but i have no idea what to do in going about changing it.
I've looked on the net and the video help guide sites for bikes, but alas i probably cant think of the proper name for this part and that's why im not finding what i'm looking for.
any help would be greatly appreciated
