Look at the geo specs of your beloved bike and see what bikes have similar geo. Did you get any help from a bike shop?
http://www.specialized.com/ca/en/bik...mpact#geometry this at least gives you an idea if you are looking online to compare geo stats. I would phone around your LBS and see if any carry any WSD bikes in your size. You might even find your model somewhere. Have you searched online? I know they don't sell per se but some stores list stock. http://www.labicicletta.com/bikes/sp...lete-bike.html
