I have a Specialized Allez road bike model year 1999. The bike is a 3x9 with shimano 105 components. I need to replace the shifters, and I want them to be shimano 105, uletgra, or dura-ace. I don't know what is and isn't compatible - I've been looking on ebay but I don't know what to look for to ensure compatibility except that they must be 3x9.
For example, I'm looking at these but I don't know if they will work:
