Shimano wheel throughout. R560, which I think was around ultegra level a few years ago.

About 1.5 years ago, the LBS tried to tinker with it when they first noticed a little bit of wobble when inspecting the bike for me after a mild crash. The verdict from them was that the freehub didn't need replaced.

How do you tighten the freehub? (just curious...I don't have the tools, but I may be able to get them from a friend)
