I thought the old blue monogram seat might have faded so I took the cover off. It’s even lighter blue underneath (because the top of the seat is dirty). It’s even more apparent in person than in the photos. Everyone that sees it says, “Cool bike! What’s up with the seat?” None of my Schwinn seats really match the bikes they’re on, but I’ve concluded that this seat is a replacement. If anyone happens to have an opaque blue ‘73, they’re welcome to have this old blue seat.
