Wrench question
I want to remove this freehub. My 10mm hex was too small so I ordered a 12, assuming (falsely) that this would have to be it. The 12 is too large.
Does anyone know if this requires a special tool? It is off an older, mid-level, Giant Cypress. It has a Shimano Altrus RD if that matters. Thanks!

This sounds like an off brand hub, so it won't accept a Shimano freehub body. So there are very few reaosons to remove it and that might be why it takes a non-standard tool.

Ok, I just ordered the 11mm. I've read the advice to chuck the wrench in my vice and turn the wheel. I just want to verify that this is a normal (RH) thread.
Also, some people say the some hubs have to be turned out from the ND side. If this is the case, would it still be a RH thread? Thanks!

and most "non-branded" hubs are made by a company called Formula... They love to swedge freehubs in place because it's cheaper than cutting a twelve point hex into the freehub's I.D.
clean the grease out and take a good look.

Yes, it is a RH thread, but that's only half the story and can be misleading. That's because the nut acts from the back to draw the freehub against the shell. So, removintg the freehub means moving the nut deeper into the shell, or turning it to the RIGHT. That might be why some people think you have to work from the opposite side, where you'd be turning to the left as expected.
