Replacing 9 sp cassette – decisions, decisions
Due to neglecting chain wear, I now also need to replace the cassette on my 27 speed hybrid. It is a HG50 12-23 cassette, with 12-13-14-15-16-17-19-21-23 teeth sprockets.
The sprocket that is most worn is the one with 17 teeth. This made me think that it might be a good idea to get a HG70 13-23 cassette, as I notice they come in this configuration: 13-14-15-16-17-18-19-21-23. I was thinking that it will make sense to have one more sprocket in the area where I seem to do most of my biking , as the 18 bridges the gap between 17 and 19 on my old cassette.
I do not think I will be missing the 12 sprocket much. But is the practical difference between 17 and 18 really big enough to bother with?
Comments appreciated.

I think that is a good idea, either the 13-23 or 13-25 if you need a lower gear.

You have to replace the cassette anyway. I suspect that you rarely, if ever use the 12 tooth cog. By all means, try the 13-23 set. The worst that can happen is that you don't use 18 all that mutch. No loss, but it may just be the thing. Get it. bk

I recently switched from a 12-23 to a 13-23 precisely because I needed the 18 cog. On the big CR, I ride mostly in the 16 to 21 cog ranges. I felt a big jump in gearing from the 17 to the 19. Now, with an 18, the gearing is very evenly spaced in the range I usually ride in.
Don't miss the 12 a bit.
