Hello, this is a nice looking logo. We at first though that the tire and sledgehammer were the thing, but now the gymnastic rings show that other metaphors can be used as well. Also, the red lining around the logo is working great as well.
#14 is clearly a logo we now consider to be potential winner of the contest. A question: if you would reuse the idea of using a wheel in the logo, as we proposed in the beginning, what would be your take on that.
