Always thinking upgrading Bottom Bracket is not a simple task especially I am not a professional mechanic. That's why this video will show you that upgrading BB for beginner is not impossible. You can do it !!!
I am not replacing my Brompton BB with expensive one because I think original Brompton BB is still durable and inexpensive.
Please see my video for more details on installation and final look. Thanks for watching and happy Bromptoning,.
