« on: August 28, 2015, 10:37:14 PM »
Hello everyone! I want to ask you a question! I know a little about the difference between BSA and BB30. BSA is English standard and have screw thread inside the hole ,usually use in shimano,while BB30 is Italian standard and don't have screw thread, usually use in CP. But I wonder if they have some other difference. I will be appreciate if you can tell me ~ Thank you!
