I recently just sold both of my bikes on CL. My first posting resulted in zero emails until I took the time to take high res pictures of my bikes in decent lighting. I posted about 8 pics of each bike in the CL ad and was inundated with emails the day I re-listed the ad. Both of them sold within a week of the posting.
Good luck with your posting, if you don't get any hits, throw more details in the ad and include a ton of pictures.
