I bought this bike a little over 5 years ago for my wife who rode it probably about a dozen times in that timeframe. Ultimately she doesn't like riding it, and it's now a candidate for a new home. I replaced the front derailleur cage not long after acquisition, other than that, everything on the bike is as it was when purchased. It's an aluminum body with carbon forks. I believe it's a 3x9 for gears. It has Shimano components - mostly Sora, but the the rear derailleur says Tiagra. The Schwinn sizing guide says Medium is appropriate for riders 5'7" - 5'10". My wife is probably just under that. The bike is generally in good shape. If you're reading this, the bike is still available.
