But they only make it in english thread not italian , If I hear of a bottom bracket(isis) that is lighter and as STRONG as what I have I will buy it.

I just fitted my bike with an FRM ISIS bb. Italian thread and 175mm CU2 cranks. It weighed 134gm. Bearings are easy to replace, I checked witha local bearing distributor who told me they have them in stock. To me it all added up to be a no brainer. I think other parts of the bike are going to need looking at before the BB.
