So after a year of contemplating (and the process was accelerated by the recent theft on my bike as well as my wife's), I pulled the trigger and got the BAB Tandem, now in the post. I have never build up a bicycle before let alone a tandem, and if anyone have any suggestions on certain things to watch out for or recommendatinos, it will be greatly welcomed. So far, I hear that I need to invest in a good large disc brake which I agree for enhanced safety. Thanks!
