You'll need the whole derailleur I'm afraid.

You don't have to go for an ultegra derailleur a 105 one will work perfectly fine and will be a bit cheaper too.

The answers above are slightly inaccurate. You know you’ll need a whole new bike.

You can buy one of these to extend your existing derailleur’s range.

Be careful of eBay knock offs. They have a propensity to bend.

I bought a genuine ultegra long cage, a little tricky to fit - worked very well.
Not a knock-off, proper Shimano part.

Think you’ll need a longer chain as well as the cassette so include that in your budget

You might find your existing derailleur will work, give it a try. If it doesn't the Wolf tooth adapter is a good option. SJS do a cheaper version.
