I have a Viscount 2169 with Bikeway Aero stamped on it.
Viscount 2169 seats were sold as Viscount seats but major manufacturers could buy them with their company emblazoned on them.
You can see the writing on the side of the seat at the top of the seat post.
Here is a Viscount 2169 in its more common form
It would therefore make sense that Bikeway Aero is a company who paid for such a privilege.
IN NO WAY A REPOP
