    Ultegra, Can I change the short cage to long?

    Is it possible to change the short cage to the longer one or do I just need to just buy a new derailer?

    More details...
    I just purchased a 2016 Fuji Gran Fondo Classico One.1 with Ultegra shifters/derailers and a 105 11-28 cassette. Would like to go to the 105 11-34 cassette but this is a short cage (SS) derailer, not the medium cage (GS). Can I just change the cage and add a few links to the chain to accomodate the larger cassette? Or do I need to change the entire derailer? If I can change the cage, what would be a good source for just that piece?

    You can, but seems that would be more trouble than its worth. Just buy a used GS and sell your SS. Likely an even monetary swap.

    'brifter' is a lame word.

    You don't want to add links to a chain either. Replace the chain.
    I work for some bike racers
    I've got some bikes, some guns,
    and a bunch of skateboards

    Thanks for all the excellent info. I found a new 8000 series Ultegra rear der for $73 on sale at Competitive Cyclist. The Ultegra 11-32 cassette and chain are both on a discounted price right now too. That looks like the way to go. I'll accomplish my goal of getting lower gears for under $200 and get a nice upgrade in the process.
