• Wonder if anyone might be able to help me.

    I have a 2012 croix de fer that had a 9 speed tiagra groupset on it.

    As these never played well with my hyrd calipers I got a secondhand rival hrd 11 speed groupset. I was hoping to just change the freehub on the wheels (Shimano FH-M525A) to an 11 speed road one but can't seem to find that anywhere. Apart from getting a new rear wheel do I have any other options?
