|Did I get the wrong hub body on my new wheels?||jzinckgra|

|I ordered a pair of AC350's with the AC rear hub. I specifically asked for the shimano compatible hub body. When I got the wheels today and tried putting on my dura ace 9 speed cassette, I noticed that the ridges (i know they are called something else???) on the hub body are all of the skinny width, whereas the grooves on my casette are of the wider type, except for one. Is this a campy hub body and not shimano? I can put the cassette on, but it is not a tight fit since the cassette grooves are wider than the hub body ridges. Any advice here? Probably have to send it back.|

|Campy freehub splines are COMPLETELY different, you wouldn't be able to fit a Shimano cassette at all and vice versa. Do you have the lockring torqued to spec?
The picture is is a Campy freehub.

|I haven't even tried tightening down on it yet. The cassette fits perfectly on the hub body of my cane creek rims. On that hub body I have 8 wide ridges and one skinny....the same as the cassette. However, on the AC hub, there are 9 skinny. When I put the cassette on (without tightening) there is a fair amount of "play".|

|AC makes all the splines the same width, why I don't know. Be sure to keep the cogs lined up as you mount them, or your shifting won't be as crisp. I've been using an AC rear with Ultegra cassettes for at least 1500 miles, and haven't noticed any damage to the splines.
Once you tighten the lockring down, the play should diminish, and remember, once the cogs are tight against one side of the spline, they'll stay there, since the freehub freewheels in the other direction. Be sure to grease the body and threads, though.
