Hah, I find it funny that a good number of you are bashing on this and saying suck it up, while in other threads, like the skate superstitions threads that have been made, I see a lot of you write about how you can't skate a board if it's a millimeter off or if the top ply is a certain color, so you'll replace it, or how if your griptape chunks out at the edges too much or gets too dirty you'll peel it off and replace it, etc. If there are people who are bothered by things as trivial as that, then I'm guessing something like a big chunk missing from a wheel would be enough to bother a good number of people on here, despite all the "who cares just deal with it" responses that have been given. You don't think you care, until it happens to you and everytime youre looking at your board you just see that chunk staring back at you. Skateboarding breeds certain types of neuroticism, especially those pertaining to your gear, so I can understand all the other replies on here about chunks missing from wheels, and all the other replies in other threads about not being able to skate a certain griptape, a deck because of the top ply color, etc.
And a chunk like that would just get bigger and bigger over time. What happens as you keep riding on it and run over more pebbles and rough asphalt skating around? It opens it up more and makes the chunk bigger over time, which can effect the overall quality of the wheel.
But whatever, I already know this post is just gonna keep getting the same "dude, just deal with it" responses, so keep em coming!
