Schwinn made parts for their own bikes. They were like tires seats and pegs called XS. Got here a rider sticker that rode their parts named Sandy Carson!
(Just the sticker is for sale) Look at the pics. What you see is what you get. PayPal or (MO to PM). Flat rate shipping in the lower 48 states. Shipping international is going to be extra. Ask any questions. Thanks for looking.
