I believe these alu Schwinns were made in conjuction with Klein. They're very nice rides. However....
The bugaboo of this design is a quill seatpost with an expander bolt rather than the typical seatpost binder bolt arrangement. The posts tend to crack very easily, and once they do, no easy way to ride your bike as replacements are difficult if not impossible to find. So check the post carefully before you purchase. Any sign of cracking, pass.
