Should I get a new casette?

Road Cycling “It is by riding a bicycle that you learn the contours of a country best, since you have to sweat up the hills and coast down them. Thus you remember them as they actually are, while in a motor car only a high hill impresses you, and you have no such accurate remembrance of country you have driven through as you gain by riding a bicycle.” -- Ernest Hemingway

Should I get a new casette?

I currently have a shimano 105 cassette that is 11/23. What advantages/disadvantages are there between the 11/23 and the 12/25 or 12/27? I realize the gears are bigger but how usefull is it? Nothing is wrong with my current casette.

If you aren't having any problems climbing then don't worry about it. That is the benefit of the larger gears. The tighter clusters like you have are great since the gears are closer together. They just suck for weaker riders like myself that enjoy climbing a lot.

If you're climbing a steep hill you're going to notice a big difference between a 23 and a 27 . . . I even noticed a pretty big difference when I switched from a 12-25 to a 12-27.

Can you maintain a reasonable cadence in the 23 on your toughest climbs? If yes, no need for a new cassette.

If you're struggling to keep a good cadence on tougher climbs in the 23, get the 12/27.

How hard is it to swap the casette?

Is there an advantage of the 11 gear over the 12 or is that neglidgable?

To swap the cassette, you'll need a chainwhip and a freewheel/cassette removal tool, which attaches to a socket wrench.

The only advantage of the 11 over the 12 is if you're spinning out with the 12 and the big ring on a descent or a sprint. Otherwise, it doesn't matter, since I doubt you spend a lot of time that far down on the cassette.

Or a tailwind. Infrequent where I live now, but does happen on occasion. I was on a ride last summer and it happened to me. I went to upshift and there wasn't another gear! I was already spinning quite nicely in 53-12 at over 100 revs per minute when I tried to shift. The ride back was a wee bit slower.
