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

11-23 or 12-25**********?

Have been using 11-23 for past 4 years and am thinking about going 12-25.
Anyone have any likes,dislikes, fors and againsts...... I know its a personal thing.

I realise 11-23 you gotta work a little harder when climbing but hey i hit 47yo this month and am not out to break any more records? Not that I ever did!!!!!

BTW I have used Dura ace 7800 cassettes for the past few years and had a new one priced yesterday...... $370.00AUD for a new cassette v's $180 for Ultegra.... Think I'm gonna go Ultegra
Any ideas.

No reason to use DA cassettes except for weight, I don't think anyone here really uses DA cassettes even if they're running full DA. At least that's the impression I get from posts I have read.

I'd say go with the 12-25 but I personally am enjoying having multiple cassettes. I'm using a 12-21 for crits at the moment and a 12-26 for most of my road races and climbing training. I'd like to get a 12-27 and a 11-23 too.

What crankset are you using? 53/42? 53/39? 52/39? 50/34? Triple?

For most people it's true.

Some people feel that a DA cassette is worth the money.

Perception is reality.

The answer to the question should be simple. How often do you use the big ring and 11T cog? If seldom, then skip it and get the 12-25. When I rode the moderately rolling terrain around Kansas City, I used a 12-21 (9 speed), until 10 speed came out in 2000 (for us Campy users). I tried an 11-23, but found the 53/11 seldom used and later switched to a 12-25. At that time they offered no 12-23 that would include the 18T cog. I found that I didn't miss the 18T, and haven't had one since.

.As for the cost and cassette life, Ti cogs last about half as long as steel. If your most used cog is one of the Ti cogs, you can expect about half the life, in addition to twice the price.

I really hate switching cassette, so now I use an 11-25 11 speed with a 50/34. I've got enough low gear for the Colorado mountains and a top gear that's slightly bigger than a 53/12. It covers all my needs.

with DA you can go 11-25 11-27 or 11-28
that way you still have the faster bottom end.
im running an 11-25 sram cassette on my DA setup and i have had no complaints in the last two rides on it and i like it more than my 12-25 but as it was said, perception is reality and i think i just like the behavior of the new cassette haha.

With 10 speed, a lot of folks would complain about the lack of a 16T. With a 50/34, it's mainly noticed in the big ring. With a 53/39 it may be a pain in both rings. 11 speed solves that problem.

meh...i just use my 15 or 17...I have never even thought "man I wish I had a 16" There is a compromise with every cassette and 15 and 17 are so close to 16 it shouldn't matter. I could argue the biggest problem with an 11-25 is that there isn't a 27 or 29 when I hit big climbs....but I don't...i use the 25 and HTFU!

12-23 is where it's at, if you are running a standard crankset. Having a 16T and an 18T is really nice. But, I do like a 12-25 to train on, or if there are longer climbs.

I do agree, i must say, with everything said. Though, given that i live in Illinois...the 12-25 is near useless to me.

SRAM OG-1070 has the sweet 16 in the 12-25. 16T plus the bailout gear.

My comment was regarding the 11-25, suggested by another poster. All 12-25 10 speeds have a 16T.

Obviously somebody has to have them or they wouldn't make them...

I've never understood people's obsession with the 16T.

Me neither, I run a Red 11-25 and a OG1070 11-25 but I am getting a new Red 11-23 so we'll see.

FWIW, the 15-17 jump is the largest, percentage wise, on the whole cassette, at 12%. That's 50% greater than the shifts at either end of the cassette. The 11-12 shift is only 8% and the 23-25 is also 8%. With 1 tooth jumps the percentage difference decreases with increasing cog size, so the 16-17 shift is only 6%. At some point, 1-tooth changes become so small that they can be scarcely noticeable and 2T jumps make the most sense.

I don't miss an 18T tooth at all, but a 16 I do. Despite that, I used an 11-25 (10 speed) all last season. I got used to it, but there were certainly places where dropping from 100 rpm to 88 just felt excessive.

Would this give an argument for using a compact (talking about a 34) with an 11-23 since the jumps are smaller compared to a standard with the 15-17 jump? You get the 14T with a compact, which fills the void from the 15-17 jump on a standard crank.

Also, I've always wanted to try out a compact for climbing and such but I have not found anything convincing enough to not just simply just throw on a 27 or 28 cassette.
