This is not an endorsement, obviously, since I didn't buy them. But there's a pedal I found a couple years ago that I intended to buy for a build that never happened... it was very slim with grip tape and came in a variety of colors. No ball bearings, the housing basically makes a long bushing that captures the spindle with a dust seal by the screw. Don't they look cool? Like putting your foot on an Apple Watch and mashing it down over and over.
