I have had a couple of pairs of posh Ritchey pedals pver the years as I am always tempted by the weight and lovely slenter designs (pretty and practical in the mud), but in both cases have been let down alarmingly quickly by the use of a bush on the innermost bearing when met with good old British winter's mud, muck and rain, so now I stick to "proper" bearings only, with decent seals, and that means mostly XTR & XT Shimano models.
