    You are referencing an English threaded bottom bracket. The next question would be “what is the bottom bracket shell width?” Some BB’s can accommodate 70 mm or 68 mm. (FSA Megaexo.)

    there is no such thing as an english threaded 70mm wide bottom bracket.

    if it's a 70mm wide bottom bracket it's got italian threading.

    68 and 73 are generally english, with 68 being most popular on road bikes and 73 on mountain bikes. there's one or two that are wider yet that are used on freeride and downhill bikes.
