Campy 13-26 cassette vs 12-25Rob

What is the general concensus on which is the better all around cassette. I rode the 13-26 last year on the hills and flats. I was thinking of switching to the 12-25 this year.

Some would say you have to have the 12 (nearly 35 mph at 100 rpm), while others argue that if you're going that fast downhill, you could go just as fast in a good tuck. If you can sprint out a 12, then you wouldn't have this question. You're the only one who can decide what gears you need, but the fact that you're asking the question suggests you really don't need the 12. There's only a 4% difference between the 25 and the 26 (8% between the 12 and 13), but you are the one who's climbing the hill and know whether you don't need the lower gear. If you don't need the 26, then consider getting out of the box with something like a 13-23, which gives you a 13-19 straight block plus the 21 and 23. Your choice.

The BIG advantage of the 13-26 is that you get a straight block up through 19! This is a big plus in my book.

If you need a high speed gear just swap out the 13 for a 12:
12, 14, 15, 16, 17, 18, 19-21, 23-26 <=== Muy bueno!

Another alternative is a custom 12-23 but that takes special spacers.

I'm going from an 11-23 to a 12-25. The 11 is just an absolute waste unless you're used to sprinting at 40mph. The fastest I've ever gotten in the flats is 33mph and I may have maintained that speed for 150 yards.

I ride in relatively flat terrain with some hills, so I could use a 25 more than I could use an 11.

The question is what would you give up by switching to a 12-25? The difference between a 26 & 25 is so little that I don't think you'll notice the difference. If you should, ultimately it will make you a better climber, IMO.

Go for the 12-25.
