White nylon plastic with a matte finish and slight grainy feel.
About this Product
These two plastic (white) pucks will repair your BikeE recumbent seat. You may need to order two pairs, one for each seat bolt. Note that they do not have the screw hole in them. They work without the screw, and are stronger for not having that hole in them. Just put them on the clamp rod and align them as you slide the seat on the bike.
