hi all,
im just wondering whats the difference bet an "english" bottom bracket and an "italian" one? can both of them fit on identical frame or must the bracket "hole" be different?
thanks
 
They require different types of thread cut into the shell, and also a different shell width. The drive side thread of an English type is reverse (left hand), while Italian has normal threads both sides. The bottom brackets are not interchangeable; a frame is made for one or the other.
 
yep, so the long & the short of it is that you cant mix & match.... italian is italian & GB is GB

do a few searches on here & am sure you'll find the technical differences

italian has both right handed thread & british is a left & a R/H thread also the british shell width is 68mm and italian is 70mm

thats the crux of it
any particular reason?? putting a new ride together are you?
 
Hey thnx both of you for the reply :D
