Had a set of new 2020 Tyrolia Attack13s mounted at a reputable local shop (big name in online sales too). My DIN is 8.5 and the heel pieces were set to that. However, the toe pieces were set to 5.5 and the shop tech explained that the springs in the toe pieces were just “tight” and in order for the binding to pass the release test, the toes had to be set down to 5.5. He made it seem like this was no big deal but it sounds rather fishy to me. Any thoughts?
