Im just wondering if there is such thing as a Concave bearing that would fit an E1ns. Because the concave I have gives it a really bad vibe, as apposed to the stock Metric bearing that is vibe free. Im just asking I’m not going to buy one if there is one.

Thanks.

Well, there is the option of taking a flat bearing and concaving it. There’s videos online about it.
