explain this conversion

I don’t get it.

How do the screws actually “fix” the freehub?

The explaination in the article wasn’t very clear.

Des

The outer of the freehub used to turn relative to what’s inside it, allowing freewheeling. The screws contact something that’s rigidly attached to the hub body, so coasting is no longer possible.

Similar to brazing one fixxed I guess.

OK … I get it now.

Thanks
