Replacing Shimano Shifters
 

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: http://www.ebay.com/itm/Shimano-Dura...item27bf870fab

I am also looking at these: http://sandiego.craigslist.org/csd/bik/2664436298.html

Thanks for the help!

according to http://sheldonbrown.com/dura-ace.html you should be ok. I've never had 7700 or your 105 so I am just going by the webpage.
