There alot of things that we though about when designing these pedals. We really wanted a ultra thin pedal for a few reasons. Having better ground clearance and lowering your body weight on the bike are huge. Being so close to the center of the spindle allows you to push over the top and around the bottom without being able to slip the pedal as easy. You feel planted, nearly imposible to roll the pedal. Being so thin makes it easy to build light too.
We wanted it strong so we used a full length chromoly spindle. You don't feel the spindle under your shoe and I ride 510! We elliminated the conventional pedal wrench flats so the pedal body could get wider without moving the pedal out more. Those two things puts the bearings far to the outside so your foot "cradles" into the pedal. The bumps from the bearings are there and you can feel them, kinda but I kinda like it. I feel like I know better where my pedal is under my foot and it's like I have something to push against on the outside edge. Feels like concave, from side to side.
The pins are 3mm, a little smaller diameter than most at 4mm. They look extra long because there so thin. There lighter and dig into your shoe better. Shorter pins or even no pins are an option with the file tread around the edges.
The Crampon has a teflon lined, steel backed DU bushing on the inside (toward the crank) and twin sealed cartridge bearings on the outside with a locknut and sealed cap. The DU provides great support for the spindle and has the longest life for bushings (same as a crank bearing in your cars motor). The sealed bearings on the outside keeps the pedal spinning with no drag. We wanted to use larger sealed bearings on the outside instead of the smaller size like the Point One pedals because we felt like the smaller bearings would blow too quickly. The locknut secures the sealed bearings and the cap seals the dirt out. This is a bearing system that the Kona Wah Wah and the Diety pedals use. Tried and true, proven solid setup.
The best thing is it's really hard to hit the pedal. You snag pedals when you hit the front edge, where it can grab the pedal. The top of the file tread across the leading edge is 6mm thick. That makes it really tough to snag the pedal on anything. The bump where the bearings sit are 17mm but you'll skim off anything you hit because it's not a square edge. They deflect well on side hits too because of the tapered shape. No matter how you look at it, if you snag a pedal it's going to hurt but if you skim off of it, it was just a close call.
That's just a bit of what we where thinking and why we built it that way.
