Yes, there are quite a few WSD mountain bikes around. I have one from REI that is a nice bike but not high-end. It's a Novara Bonita, XS size (2004 model). The 2008 model is $589. I'm looking to sell mine as I've upgraded to a Titus Racer X, which I bought used on Ebay. The Titus not WSD, but is a size XS, and Titus tends to have short top tubes. The geometry and effective TT is virtually identical to my Bonita, even though the Bonita is a 13.5", and the Titus is a 15", so they all run differently, so you do need to go and test ride some and see what length top tube you need. For me, I use a longer TT than on a road bike due to the flat handlebars making for a shorter reach. For example, on my road bikes, my TT length (c-to-c) is around 19-19.5", where on the mtb it's more like 20.5". I am 5'1.5", by the way, just like LBTC!
If you were in my area and my size, I'd certainly be happy to sell you my Bonita for a great price
. It would be great for the C&O. Though I should probably hold onto it, because Tri Girl does make a good point about a slightly heavier bike being a bit easier (at least for a beginner like me) on technical stuff. My Titus tends to slide around more than I like on roots since it's a "race" bike and quite light. That makes it great for climbs, of course!
Good luck and keep us posted -- it will be fun to find out what you choose!
