    What tool to remove this freehub?

    Freehub on my Diamondback Insight (City bike with 700 c wheels) bike isn't freehubbing like it should. It is an 8 speed hub and should be Shimano butI don't see any parts number.

    Googling says a 10mm hex should do it but that is too small and a 12 mm is too big....don't have access to an 11mm.

    Thanks!

    According to Park some brands use an 11mm hex wrench.

    I ended up not needing to replace it. If you are using a 24" breaker bar and it isn't striping it out I would assume you have the right tool in the hub?

    Yes, 11mm should be the right tool, but I am not entirely sure about me standing on the 24in bar and not moving the bolt at all, gonna visit performance later this week...

    Instead of standing on it, try hitting the wrench with a big hammer. The impact should help break it loose. Make sure you're holding the wrench firmly in the freehub so it doesn't start backing out and strip the head.
