Once again I find myself writing about bottom brackets. Bollocks. I really don’t want to get labelled as some kind of obsessive dude who only thinks about bottom brackets all day long, yet I don’t seem to have much choice in the matter either.
Equally, I imagine that you -the noble reader- is pretty bored reading about them, but you too have little choice but to think about it. If you are in the market for a new frame anytime soon then you will HAVE to choose a bottom bracket. Most frames still come with a USA BB if you just want something you know works (even if it is a bit of a pain to fit sometimes), but most also now come with the option of a euro, some frames only come with a euro and some of the new ones to be launched over the next 12 months will only come with a Spanish or other BB shell.
