Hello. I have a question regarding this bike value. A co-worker wants to sell, and has no idea how much. I'm pretty sure it's a 92 or 93, as it has the Suntour components. Looks mostly stock, but not rear rim for sure. Hasn't had the best of care, and needs a new cassette, middle ring, chain, and rear tire, from a quick once over. Seems solid otherwise. Any ideas? Or, should i skip it?
