OK! well I've figured out pretty much everything and I've come to the conclusion of the Shimano ES-51 BB. Now the thing here is that my old BB had the dimentions of 73x113 and I've read that the LX cranks need a bit wider room thats why they come in 73x126. The only important number when chosing a BB is if its a 73mm or 68mm so it fits in your frame, the other is just length right?

Correct. The 68 or 73 is the width of your bb shell. The second # is the width of the axel. This can range from 105 all the way up to ?? I've seen 140's.

Good luck!
