These are the ones you want to use in the winter mud & sand paste. They feel very smooth and the anodising holds up excellently.
Available in Red - Black - Blue - Orange - Pink - Green - Silver - Gold
(temporarily out on gold)
They weigh a little more than your average plastic/alloy jockey wheels but are more durable as a result.
Ceramic bearings of course last longer and are smoother than steel. Pick the washer/shim that best fits your cage. Our preference is for the fatter ones for more clearance than standard widths.
They do look quite nice! Pimp your bike and beat the mud.
