Ziggyboy Bullet Z-VSC's consist of stainless steel inner-tube valve
stem covers-four O-Rings. O-Rings fit Shrader or Presta valve
stems. The first of its kind, the Ziggyboy Bullet Z-VSC is the only
valve stem cover in the world that completely covers, protects and
beautifies the entire valve stem from top to bottom. That means
that after installation, the inner-tube valve stem can no longer be
seen. They have a nice chrome appearance and soon will be made in
different colors and shapes.
