Wow this is one of the first negative posts I have heard about the IFI wheels. I just have a few comments to make about your picture and the IFI wheels all together.
1.) In the picture i can't really tell where the dent is. Do you mean on the edge of it where the picture is a little blurred? If so it looks like you hit something with it.
2.) The IFI wheels are almost indestructable. Even with dented wheels you can still drive.
3.) The IFI wheels shouldn't have taken you to long to put together. I showed a group of high school kids how to put them together and in under 10 minutes they had the IFI wheels put together and the sprockets put on them. And we have yet to have a problem, even with the original IFI wheels that we tested we didn't have a problem with them.
4.) These wheels beat just about anything you can make. They are light, and almost indestructible, what else could you ask for?
Did you try different wheels out? Such as to buy another one from IFI to see if it was the batch of wheels that made things so difficult for you?
/edit:
It took us (team 229) hitting the wheel repeatedly with a hammer to get any significant dents that would disrupt the driving of a robot. I doubt a robot is going to have its wheels hit nearly as hard in competition.
