Stuck on the BB size all, it doesn't seem obvious at all. On the BB it says BC1.37 x 24 but I don't if it's 68mm ?! Any ideas?

1.37 x 24 is standard BSA thread pitch so it has to be 68mm by default.

I should clarify that I am talking about road frames here. MTB frames can have English threading and wider BB's like 73mm and even bigger for AM and DH bikes.
