I have new AC Sprint 350s that I got on ebay, two days before the recall was announced. My rear hub did slip quite a bit during a crit last Sunday (fun, fun, fun). I called AC and no problem they sent me the part no questions asked.

The part that needs to be replaced is the plate behind the pawls that coordinates all 6 pawls so that they all engage at the same time. I compared the old and the new and it looks like the new one is thinner. All the holes and the diameters look identical.

Test rode this morning, no problem. AC will pay for a shop to do this, but I found it to be a simplistic repair, assuming you have a 19mm cone wrench, which I did not, so the LBS got some cash from me ($7 for Pedro's cone wrench, very good quality).

So if you have 2005 350's or 420's do not dispair, the fix seems to work.

Did they ask for your serial number when you called. I can't really make out mine, it's a bit smeared.

I also have two hubs that are subject to the recall. When I called American Classic regarding the replacement parts, they only asked where and when I bought them, not their serial numbers.

Like 53T says, the repair is fairly easy, and does not require special tools.

I have been using the CR-350s for training and the 58mm carbons for racing and decided to get a set of CR-350s for the wife for her birthday this year and was surprised to find her wheels were also covered by the 'recall'. I called the number a day or two after the recall was first announced and American Classic promptly sent me the replacement cam plate with a voucher. Now my workshop at the house looks like the Park Tool advertisement with all the tools hanging on the pegboard so the repair was a no brainer but I still had problems. After completing the replacement of the cam, with the bike in the repair stand, I returned the wheel to the bike and gave the cranks a turn only to discover that the cranks continued turning after I released them as the freehub did not seem to want to freewheel. I turned the cranks a few more minutes figuring the action would 'loosen up' but it actually got worse to the point where the chain would start to droop if I held the cranks to prevent them from following the motion of the wheel (sort of a partial fixed gear).

I took the wheel back apart and although I did not realize it at first, the loop spring located on the back side of the freehub body - this spring is what engages the tiny serations in the cam plate which in turn causes the 6 pawls to engage the splines of the gear on the back of the freehub assembly - was bent nearly 90-degrees. Because it was bent to that extent, the spring was not able to glide over the serations in the cam palte and was instead forcing it into the hub body which abraded that inner surface (easily fixed with a dremel). Called American Classic back and described the problem wanting to purchase a new freehub assembly but the person I spoke with said he would send me a new freehub body with the understanding that I return the old one - not a problem! I should have the replacement freehub assembly in the mailbox tommorow.
