These pedals have a 6061 T6 aluminium body, forged chromoly axle and a sealed ball-and-needle bearing combo for smooth spinning.
They come with replacement plates in different colours, in case you smash yours on a rock or you’re just vain. The stock pins are quite short, so you’ll need the additional long pins for muddy conditions.
They are pretty hefty at 589g a pair, and all the extras add to the already high price. The large surface area means they’re not great in the mud.
