Will a 9-speed rear derailleur work with a 7-speed cassette?
I have a 7 speed road bike that I bought on ebay last year. I bought it to try road riding before I went and spent the big bucks on a new bike. Now, I want to start replacing the lower end parts with better quality parts, but I want to do it piece by piece. I'm not ready to replace the hub, cassette, chain and STI Shifter, but I can get a good price on a 9-speed Ultegra. Any thoughts? Also, can a shifter on a 7-speed bike work for a full 9-speed set-up? It seems that I have an extra index or two on the shifter.
Thanks.
