Ok I have a 1991 (I think) Giant Iguana (no it doesn't bite) and I have a decent amount of wobble in my bottom bracket when I grab the pedals and shake. I need to know the pertinent info for a new bottom bracket. I have been told it is english, 68x118??? Is there any other info I need to get a new one? Do you have any recommendations on a make and model of bottom bracket? Next I would like to know what measurements and make and model crankset would fit my new bottom bracket. The crank that is on the bike now is a Sakae Enhanced Ovaltech 48x38x28. I took the chainrings off today and cleaned them and they are pretty ate up. Thanks in advance for all the info.
