By having a removable steel pins on one side of the pedals, you can depend on having your feet stay on these Eclat Contra pedals because of the grippier pins.
Eclat created a custom axle that uses a smaller caged bearing, but stays thicker closer to the crank arm where you need the strength the most.
By using removable pins on only one side of the pedal means BMX street riders can still do grinds on the all plastic side too, which is awesome!
