I was born into a camping family in Minnesota and in my late twenties I fell in love with backpacking. I have spent a thousand(s?) days nights in the backcountry of Minnesota and Montana on foot, splitboard, and bicycle.
These are average bearings and I would recommend paying a bit more money to get something of superior quality. I bought these to replace some old bearings that were in a board of mine and the old ones actually still had far better glide left in them than these new replacements.
