2012 Trek Skye SL Disc

Hello.. I have a women's medium size (16") 2012 Trek Skye SL Disc hardtail mountain bike for sale. I have NEVER used it. I literally bought it, hung it up on my wall rack and it's been there ever since :/ I just can't find the time to go ride the trails. It is completely stock with all the components listed on the Trek website. I'm also willing to trade for a a 54cm road bike. I have pictures but they're on the craigslist ad and can't figure out how to load them here for the life of me. PM me if interested and I'll email you the pictures. I'm asking $550 obo. Thanks for looking!
