my normal response to a cryptic 10 speed ad is to ask the seller what it says on the frame--any decals or any painted words. you can usually get them to respond much quicker than asking for a photo and that will usually give you an idea of whether it is worth it to look further. if you ask for a photo, they may not have a digital camera or they may not know how to post pictures, or they just may not have the time to do it for a few days. that's critical time you can't afford to loose if it is a good bike.
