Years ago I had an issue with these cranks getting a hole on the chest and filling with water, making them useless. It appears the front hook punctures it. So I steered away from them. Buy six more last week, and the exact same issue again.
I can't think of anything I'm doing to make this happen, and I don't have the issue with any other crank. Not bashing the product, just curious if anyone else has run into this.
