hi all!
i just got from ebay a nice fixed hub with sprocket and lockring tight, i wonder if there a way to remove the sprocket without clamping the hub shell or ruining the finish of this campy hub.
thanks a lot!

This (like everything) has been covered before. Someone said that they'd done it by wedging the hub in a bench vise with some wood and torquing the cog off with a chainwhip. Someone else mentioned lacing the NDS up and seeing if that gave the wheel enough strength to pull the cog off.

Good luck.

I'd just lace in about 8 or so spokes (loosely) to a junk rim and go at it.

Its a real PITA when folks do this, its just bad form to sell a hub with a cog and lockring that haven't been broken free.

Folks have pretty much covered it, either use a bench vice (though depending on how tight things are, you may not have enough leverage or be able to prevent the hub shifting) + wood, or re-lace the hub to a junk rim and do it that way.

Either way its going to be a pain.

True, but this, (like everything) is nearly impossible to find using bikeforum's broken search function. (another kick to the dead horse)

Stick the cog side of the hub up the *** of the idiot who cut it out before removing the cog and lockring and turn.

you may be able to use an oil-filter wrench on the drive side hub flange, if it is a high-flange hub.

I'd use some sort of band-clamp pipe wrench on the hub. Might have to mount it in a frame to rotafix the cog off. I haven't done this before, just saying how I'd go about it.
