'88 Schwinn World Sport. 6-speed rear freewheel/sprocket assembly with QR skewer. Front skewer also.
Original wheels aren't great; rusty, noticeable lip at seam. I want to replace with similar size, but new. Tires are marked "27 x 1 1/4." Actual outside rim diameter is app. 25 1/4". Do I want a 26" or 27" rim? Can I buy a complete front and rear wheel/spoke assembly? Thanks.
