further more, if you at look both the sprockets available from ifi and am.biz, you'll notice that they both are made to accept a 3/8 in bore flanged bearing. |

Re: pic: Problem with IFI Wheels
I noticed some similar wear on one of our IFI wheels from last year (the 6"x1" version), but it wasn't worn that badly. Also, the wear seemed more like it came from the bearing turning against the wheel rather than being wollered out due to a deformed wheel plate.
...My theory is that the bearing wasn't tightened down enuogh when our wheels were put together. The supporting evidence: when I was playing with one of the wheels that was laying around the shop, I noticed that one of the bearings was actually able to turn against the wheel! The screws seemed tight enough, but it was still able to turn. It's my guess that the little white standoffs that go between the plate and the screws were too thick and didn't allow the screws to clamp down tightly on the bearing. I didn't think much of it at the time, but it's my guess that this is what happened to your wheels (though I may be wrong...). We've never had any deformation of any kind on our plates, and we were using the 6"x1" wheels last year (we were being pushed sideways for a good part of our matches, too). |

having the sprocket bolted to the wheel with both bearings in the wheel does create a high stress cantilever that i can see being enough to round out that whole, especially if there were any nonconcentric sprockets in the drive to pulse the chain from tight to really tight. putting a bearing in the sprocket should stop it because if relieves the cantilever |

Re: pic: Problem with IFI Wheels
Well, he forgot to mention that the wheels were rotating at about 1000 rpm. To do this with #25 chain means that you could play a tune with all the tension we have on the chain. We put bearings in the sprockets and haven't had any problems since.
