I've just upgraded my rigid steel to 1x and fitted this narrow wide. Even riding hard trying to keep up with my son on a full sus @ Cwmcarn didn't cause my chain to come off. And the orange is beautiful.
Bought the zs56 in orange, really impressed by the quality, the bearing fits nice and snug and doesn't fall out and the seal slotted into the crown race is genius. Uses 40×52×7 45°×45°bearing which feels nice n smooth, a quality bit of kit.
Great pedals for the price. Come with enough pins for both pedals in two different lengths, so you can go with what suits you best. Great grip. Large platforms. Excellent value, especially when on offer.
