Hi
I have just bought a 2006 Orange 5 frame, I intend building it over the next couple of weeks, just one thing I cant find out from the orange archive site.....What type of BB was fitted to these frames ? I know its 73mm, but does it need to be internal or external, (what length shafts) ?
If I had a selection of BB's & cranks I would try some to see what works & what fouls the cranks, but I have to buy a BB, so want to make sure I buy one that fits first time, so hoping that you good folks can help :)
