I'm converting a 1989 Trek 830/Antelope MTB to a commuter and it has a freewheel. Can I convert it to a cassette with the same hub?

    I'm sorry but I don't see a question here. Stackexchange is not a forum where a generalised discussion starter like this is appropriate. Could you possibly edit this down to a specific, answerable question?

    Why? You can still get decent freewheels pretty cheaply (10-20 USD).

  • Depends what you mean by same hub. Also I agree with Batman in that 7 and even 8 speed freewheels are inexpensive. What is your goal in moving to a cassette? How many cogs does your current freewheel on your MTB have?

No, it is not possible. You need to replace the entire hub, and the easiest way to do that is to replace the entire wheel.

    Also, with a 1989 era bike that probably means spreading the frame so it can accept a modern hub.

  • Modern MTB hubs which don't use thru-axles are likely to be 135mm OLD, while "retro" MTBs may be 130mm at the rear... Such a frame is unlikely to be using disc brakes, so there's no reason not to use a 130mm "road" hub.
