Svar fra SkatePro: Thank you for your review.
You are right, the wheels are not supposed to be in contact with each other. However, in your case the frame is a very tight fit, and the Matter wheels are a bit larger than 100mm. Normally this would give you a bit more wheel to wear down, but this keeps the wheels from fitting on your frame. For this reason, we have contacted you directly on email to help with this case.
