Does more pins equal more grip?
Pins are what give you the grip interface between a soft compound rubber mountain bike shoe and a flat pedal. The logic is that a greater number of pins gives you superior grip, and the longer they are, the more secure your shoe-to-pedal interface is.
Having more pins might be theoretically superior, but they don’t help if the distribution of pins isn't right. Pin placement is vital and this is where the pedal engineers really earn their money.
