Schwinn built this line of aluminum frames in conjunction with Klein. As such, they're very nice rides, except for one thing.

Instead of a traditional seatpost binder bolt, you get a quill seatpost. This design is very prone to cracking. Inspection of the entire seatpost before sale is highly recommended if the seller allows it. Replacements are not easy to find. You can fashion a stem into a seatpost (RJ the Bike Guy has a video somewhere), but it's a lot of work.

There is one workaround - the Gorilla Park double bolt adapter. Sits in the seat tube opening and holds a 27.2 post. This example is no longer available, but I could probably find another if given enough time:
